Hi,

It's been a while since I gave solutions since I myself have been busy with my works. Anyway I managed time once in every three/four days to compose the answers and finally it's here - the complete explanation/solutions to official UCEED 2016 previous paper.

You can download the question paper - UCEED 2016 question paper here

Section A: NAT 

1) 19

We know that a pyramid has a base and triangles connecting the base sides and a common point. Usually the base is square. In the given question, pyramid base size (7cm) is greater than the size of the cube (5cm). So, some part of the pyramid will protrude out. Picture below shows the pre step of adding the shapes.

Below image shows the 3D view of the solid formed after joining. Sorry for the poor drawing, but hope you can visualize that. Note that the top portion is also a small sized pyramid shape. As can be seen the shape is in symmetry.

No. of faces in front direction = 2 (not considering the slant portion)
No. of faces in other three directions (right, back and left) = 2*3 = 6

Surfaces from top = 9
Surfaces from bottom = 2

Total = 2+6+9+2 = 19

2) 26

In the below image, I've marked the different symbols with the letter '1' in red.

3) 8
Couldn't spend much on this coz of time and this one is really tough, have been scratching my head on how to solve. Will check this again during free time and update about the way of solving this question.

4) 11
Below figure shows one possibility. We can have similar possibilities.

5) 50

Before cloning the shapes, we will count the no. of triangles so that we can just multiply the number of triangles after cloning by the number of clones. Below image shows the same image in two separate forms. Number of triangles are 6. Now, since we are cloning to the left and then to the right, and finally the whole (3 patterns) to the bottom, we will have six such patterns.

Now, after cloning, we can count the following 4 triangles as shown below.

The following two images shows further number of triangles as 8.

Finally, the below image shows 2 triangles formed.

Total no. of triangles = 6*6+4+8+2 = 50

6) 26.17

Net profit of the company = 68799-2456-4789 = 61554
Now, operating Profit Ratio = 61554/Sales = 61554/235126 = 0.2617
So, 26.17 %

7) 12

The several possibility ways are
A-D-G-H-I
A-D-G-H-E-B-C-F-I
A-D-G-H-E-F-I
A-D-E-H-I
A-D-E-F-I
A-D-E-B-C-F-I
A-B-E-H-I
A-B-E-F-I
A-B-E-D-G-H-I
A-B-C-F-I
A-B-C-F-E-H-I
A-B-C-F-E-D-G-H-I

8) 85

The problem can be solved as follows.

Given:
8 men and four women shook hands with same gender. So, it mean there are 4 groups of 2 men each, whom shook their hands with each other, totaling to 4 hand shook consisting of 8 men. Similarly since 4 women found that they shook with same gender, it mean there are 2 groups of 2 women each which counts to two hand shakes. Got it.
So, outting it like
MM + MM + MM + MM + MM = 8 men and 4 shakes
WW + WW = 4 women and 2 shakes
counting to total 4+2 =6 hand shakes,
Given, total hand shakes is 87, so the left (87-4-2 = 81) hand shakes has to be done by a group consisting of one men and one women each that is MW.
Adding these 81W from the 81 groups to the 4 women earlier we get 85 women as total.

9) 65*(25/60) minutes

It's obvious,

For every 60 ticks of the minute hand, the hour hand would have ticked 5 times.
put it like

60 ticks of minute hand = 5 ticks of hour hand

So,
1 tick of minute hand = 5/60 ticks of hour hand

5 ticks of minute hand = 5*5/60 ticks of hour hand

Now, after the 12 o' clock, they will meet somewhere after an hour, i.e. when the hour hand is near to 1 hr and the minute hand also at the same location.

That is, the minute hand had to travel an whole round (60 ticks) when the hour hand travels to 1'o clock. But still they haven't met. The minute hand has to travel further to 5 minutes, adding to a total ticks of 60+5 = 65 minutes.

But by the time the minute hand reaches the 5 min zone (number 1 on the clock), the hour hand would have moved 5*5/60 = 25/60 past number 1 (5 min) - check above for how 5*5/60 came). So, approax, they meet at 65 + 25/60 minutes


10) 12

Similar question has been solved already in my solutions to previous papers.
If it's just circles, then around a coin/circle, we can place 6 circles, but now the situation has spheres, so apart from this 6 spheres on the same horizontal plane, 3 spheres can be placed above and 3 spheres below. So, total 12 spheres. Hope you got it. If not, I can draw and explain you!

11) 99

Given Tank dimensions = 20X5X10

Volume of water that can fill the tank = 20*5*10 = 1000 cc

Given volume of water already in it = 307 cc

So, balance volume to be filled with bricks = 1000-307 = 693
Volume of brick = 5*2*1 = 10 cc

but, given that the brick absorbs 30% of its own volume, which will be = 10*30/100 = 3 cc

so, it mean if we place one brick in the water, it will consume 3 cc of water apart from displacing the water.

So, it's better t oassume that the volume of water displaced by each brick will be = it's own volume - volume consumed by it
= 10 - 3 = 7 cc

So, the required no. of bricks = 693/7 = 99 no's

12) 12

check the below image

13) 1068

Given dimension is 48m X 1.2m,
converting to centimeters, we observe dimension as 4800 X 120 cm

Now, the below picture shows one best possible arrangement. As can be seen, arrange two sheets in a row, such that 25 side is vertical and 21cm side is horizontal (shown as two sheets) in the left bottom. And also arrange three other sheets such that 25cm side is horizontal and 21cm side is vertical. Three of such sheets can be placed.

Now consider the bottom left most sheet, similar sheets when placed vertical will occupy 4800/25 = 192 sheets.
Since there are two such sheets, we have 192*2 = 384

Now, consider the sheet placed such that 21cm side is vertical, placing such sheets one above other, we can get 4800/21 =  228
Three such columns are there, so, 228*3 = 684

So, total no. = 684+384 = 1068

14) 22

Most of you might get 21 as answer, but let me show the hidden tree branch which you might count as 2 instead of 3. This is the right most part of the given image.

15) 33

Instead of drawing the whole image, let me show the part given by them with illustration of what happens when we join sides. As can be seen, the semi circle at 1 will form a circle, similarly the triangle at 2 forms a rhombus. Similarly the cut at 3 forma a square. Neglecting the shapes at 1,2,3, let us count the number of shapes as 6. Since there are four such patterns. So, total number neglecting 1,2,3 is 6*4 = 24.
Now, total no. of 1's = 2*2
total no. of 2's = 2*2
total no. of 3's = 1

SO, total no. of holes = 24+4+4+1 = 33

16) 26

Below I've identified the faces with glasses for your benefit. But, remember, during exam, you have the face questions on the computer and not on paper, so, you need to do this mentally. So, use your concentration for figuring out the required.

17) 810000

The best possible combination is in order below
 1) press 9
 2) press 00
 3) press X
 4) press 9
 5) press 00
 6) Press =
So, the largest number = 900*900 = 810000

18) 10

I'm not pretty confident about this. But I tried my best to figure out. Below image shows my findings. Correct me if i'm wrong.

19) 451

20) 0.82

Probability that only one of them finds a parking space = prob. that either one of them finds a park
= (prob that car finds a space AND prob. that bike doesn't finds a space) OR (prob that car doesn't finds a space AND prob. that bike finds a space)

In probability, AND is denoted by '*' and OR is denoted by '+'

So, probability = 0.1*0.1 + (1-0.1)*(1-0.1) = 0.01 + 0.81 = 0.82

Scetion B: MSQ

23) A,D

24) B,D

32) B,C

Check the below images for explanation. I followed the following numbering for explanation

33) A,D

34) D

Unless there are sliding joint in the first three mechanisms, it cannot be folded. Mechanism in figure 4 is the standard four bar mechanism, and it can easily be folded.

35) A,C,D
By observation

36) A,B,C,D

In figure one, curve is bulging at the top, it means more aged people are there compared to infants and teens. Second graph has steady rate for all age groups. In graph 3, infants are more in no. than aged people. Remember that in developed nations, population of infants has been controlled, compared to adult and age groups or at least equal.

So, all four options apply.

37)  C

The answer is simple. Find the number of alphabets and repetitions in it. There are total 7 alphabets with two repeated (A is appearing twice).  In the options check the pattern that has this feature - that is two repetitions and total 7 items. Option C has that feature by using colors.

38) D
The questions seems to be tricky with no clue. But, the first and best check that one can do is check the number boxes in the five segments in each option, since they have mentioned that they should be continuous and have equal no. of families. Fortunately, only option D satisfies!

Update:
Checking that with the above simple way, we get two options that satisfy it. I therefore discuss with you the actual procedure for solving this problem. Considering the five patterns in option D, we try to arrange it such that the whole combination forms the rectangular grid shape as given in the actual picture, which when joined will be as shown below.

As you can see, I've marked the separate parts with numbers from 1 to 5. I've also marked the parts which according to the ques are blue (to the left of section line) and red (to the right of the section line).

Now the next image shows my explanation, showing the parts sepearately and the count of Blue and red parties according to the above image division.

As you can see, for the first part (of 10 families/boxes) 6 families/boxes are blue while the rest 4 are red, so blue won, likewise

II pattern - red won
III - Blue won
IV - Red won
V - Blue won

So, overall, blue won the election in three divisions while red only in two, so that will be the answer, Now, I hope you can check for others too.


39) A,B,C

Option A is the top view of the given image in the box. You don't have to check the whole lines initially, start with the bottom two squares formed by four different colors, observe the order in which they are arranged. Like in the below image (left pattern in the box), one of the square base has been numbered as 1,2,3,4 for red, yellow, blue and green colors respectively. Observe similar arrangement for the other base square. Now, in the options, observe these 1,2,3,4 sequence for coincidence (for both the base squares). Once you screened the appropriate options, you can now check the triangles joining the base to the top vertex for the pattern.

Note that option C is the bottom view of the given pattern n the box. So, all the color order are just reversed.

40) Water flows out through A,B,D holes

It's bit difficult to explain this in paper. But the only clue I can give is, cheek for the tunnels which are either in the same row from top or a row adjacent to the water flowing row. Because, water will find way to flow in both cases. Other than the tunnel numbered 8 in front face (tunnel numbered 8 in the front face middle, 4th row from top), water will flow in all other holes.

Section C: Multiple Choice Questions

41)  B

The answer is simple. Consider the donut shaped circle with plus/cross (+) sign as highlihted in the beliw first picture. Now, the circle has moved to the top of the center circle as shown in the second image. Let's consider it is turning clockwise and the rotation is thus 180 degrees. Now i nthe third image, the same circle is rotate di nthe same direction (clockwise) but with angle 180+90 = 270. In the fourth image, rotate the ciecle in the same direction (clockwise) but with angle 180+90+90 = 360 degree. So, obviously in the firth sequence, the ciecle has to be rotated clockwise in 180+90+90+90 = 450 degree. Got it ? all the four circled symbols inside the pattern follow the same proceedure. Now, check the option that represnets 450 degree rotated view (of inner 4 circles) rotated from the fourth sequences. Option B and D matches. Now, observe the center circle. In the first image it's a circle with dot inside, in the second image it's a donut (empty shape inside a black circle). follow the pattern
first - circle with inner dot
second - donut
third - circle with inner dot
fourth - donut

So, obviously, the next pattern should have 'circle with inner dot'. Thus option B suits

For more on how to solve this question, check the mental ability part of the resource page.

42) D

All the options have same color, so let's forget about the color criteria given in the conditions.

As given in the grid form with numbers, and following the arrow-ed directions, we get

(Grid No.) - (no. of sides of polygon)
start - 5 sides (since it's pentagon shown in red color)
4 -> 5 + 1(rule i) +1 (rule iii) = 7
9 -> 7 - 2(rule ii) - 1 (rule iv) = 4
8 -> 4 + 1(rule i) +1 (rule iii) = 6
5 -> 6 - 2(rule ii) = 4
2 -> 4 + 1(rule i) +1 (rule iii) = 6
7 -> 6 - 2(rule ii) = 4
6 -> 4 + 1(rule i) +1 (rule iii) - 1 (rule iv) = 5
1 -> 5 - 2(rule ii)  = 3
2 -> 3 + 1(rule i) +1 (rule iii) = 5

So, the final shape is again five sided, i.e. pentagon

43) C

By careful observation, this can be solved. If you're not confident, then better draw the pattern by linking similar sides.

44) C

It's obvious that the other shoe sole should be the mirror image of the given shoe. All the options might look similar but there's difference in the wave like lines at the c=middle of all the soles. Only option C is proper.

45) D

The colors are analysed as follows

For the top part of the circles
Yellow + Blue (yields) -> Dark Green
Dark green (yields) -> light green

For the left part of the circles
Blue + Red -> bright violet
bright violet + yellow -> dark brown

For the right part of the circles

Red + yellow -> dark orange
orange + yellow -> light orange

46) A
Obviously it should rotate in the opposite direction as the rotation when the water is sprinkled through the nozzles, which will be in clockwise direction for the given shape of the sprinkler.

47) C
It will not be sphere, since the question needs the portion that is common to all the four spheres. So, the sphere part is cut a bit to a shape something similar to C.

48) A

The first impression that I got after reading the question gave me a shock! was wondering whether something like hammer is used for any instrument that too musical ? then later realized that it's the kind of mechanism that they wanted. Hammering here they mean the technique of hitting the string rather than sliding (as in violin) or picking (like in guitar).

49)

I'm not sure about this question

50) A

I don't know whether there is any such mathematics existing to use parameters to construct a shape or not (I think there isn't any standard in math literature), but I do see some pattern from the given images. The values of R and r will give us an idea of how many sides the shape is having. Like R/r is the no. of sides of the shape.
For the first image, R/r = 5, so, it has five sides, (all formed by 5 circles intersecting one another)
For the second image, R/r = 5, so therea re 5 sides
For the third image, R/r = 16/4 = 4, so there are 4 sides
For the second image, R/r = 108/4 = 27, so there are 27 sides, all formed with circles.
 Now, 'c' might represent the amount of bulge of the circle used to construct the shape, in other words the curvature or radius of the circle used for constructing.
As can be observed, when c i more, the intersection is more, as compared to when c is less.

So, in the required shape, which ahd three sides, the best combination is R/r = 3 (24/8 in option) and since the shapes are bulges out, the value of c might be the least. So, option A fits.

51) C
I don't think explanation is required for this

52)  D

Obtained by following the procedure that they gave.
Below image shows the step by step change made for the given sequence. Green symbols (and arrows) indicate the change that has been made for the given pair of symbol.

53) D

Solution is simple, but bit of observation is needed.
As can be seen in the below picture, it's obvious that we don;t have to bother about circles as all the squares have two circles each. Now, observe the first and third numbered square in the below image. As can be seen. Shape A of 4 sides/peaks has been transformed to A' of three sides/peaks (with difference 1). Similarly shape B of 9 sides/peaks has been transformed to shape B' of 10 sides (with difference 1). And note that A+B = 13, as well as A'+B' = 13.

Keeping this pattern in mind, shapes in square numbered 2, viz. C and D (C+D = 13 sides) should be transformed to shapes C' and D', such that C'+D' = 13, and difference should only be 1 between them, the possible combinations as are as shown in image, i.e C' can be either 6 or 5, and D' can be either 7 or 8. Now, check the options which best matches this pattern. Option D suits I guess.

54) B

It's really tough (at least for me) to exactly figure out the pattern. However, as always, we can derive some pattern out of given sequence. So, here is what I observed. As can be seen in the below image, wherever circles are appearing in the main image (highlighted in red color), then we can see a dark water drop symbol accompanying it (highlighted in blue color).

Similarly when there is unbound lines (lines that are not closed to form a shape) as highlighted in the below image, we see the shape of two zigzag short lines accompanying that as highlighted in blue color.

Now, in Fig.1. since we can see both circles as well as lines (not rectangles), we can assume that the two symbols (water drop and zigzag) must also exist. So, option B seems to be correct. Although this might not be a correct interpretation, but this is how I solve.

55) C

Below image shows the construction. I've numbered the parts for your convenience. Note that the parts numbered 3 and 4 has to be rotated 90 degree clockwise for the final assembly and the final assembly is a flipped E. We can just flip it to get the actual shape as in Fig.1.

56) D

57) C

Dip your toe in the water -> tentative step
Come hell or high water -> Persistent in the face of difficulty
Mout hwatering -> tasty
head above water -> survive

58) B

In downward to-and-fro position, we tend to bend bit and try to push and pull the hack saw. So, keeping the handle either horizontally or vertically will only cause strain to hands and will not function well as there will be bending possibly between every to-and-fro motion . Posture in option D will separate the blade frame from the material in downward f=direction (because of handle direction being 45 degree outer), which is one inefficient way. Keeping handle as in option B works fine, and will always ensure that the tool (hack saw blade) is in contact with the material all the time.

Okay, here goes the convention :

1. Whenever tail is included with the bubble, then it means converssation is happening either directly or through whisphering
2. When the bubble is dashed with a tail, then it indocates whispering
3. When the bubble is made of continuous line with a tail, then it is a direct conversation (speech)
4. When the bubble is made of zigzag lines, it mean shouting/screeming etc
5. When the bubble is followed by a circled dots at bottom as shown in the below picture, it indicates thinking process.
6. When instead you see box, then it is just explanation of the situation (past or present or future) which is neither been spoken by anyone nor indicates thinking process but is just a narration of the situation.
7. Below image should give you an idea.

COG lies at the mid way of the mass and not at the mid if the object. So, the top surface of the T shape contributes more weight and hence the COG should be somewhere around the border of the two surface intersections, but placed little distance away from the horizontal top T surface as shown in option D.

Answer key with solutions to UCEED 2015 paper

you are here ....... UCEED  >> Answer Key to 2015  UCEED official paper

-------------------------------------------------------------------------------------------

Hi again,

This post covers solutions for official UCEED 2015 previous paper. Although I can give answers for all of them, I'm just skipping those questions that you can dealt by yourself especially passage and comprehension type. I just want to save my time for other works :P

Hope that's ok and you can manage those by yourselves. I especially want to give some short techniques or tricks on how to solve questions.

UCEED 2015 official Question paper here

Q1) 22

My way of solving:

1. Start with smallest circle size count those sized circles, 

2. Next move to next higher size and cont again the circles ..... 

continue repeating the steps until all the sizes are counted

size 1 - 1
size 2 - 7
size 3 - 1
size 4 - 3
size 5 - 3
size 6 - 7

Below images show how I selected the circles

Q2) 8

I will again apply the procedure that I used in Q1. i.e start with smallest size leaf and then proceed. In this case, you can use additional factors like zig zag leaf Vs plain leaf too! for easy and fast counting

Zig-zaged leaves types - size 1 (thin), size 2 (fat)

plain leaves - 4 sizes

Three cut leaves - size 1

snake type leaf with two cuts - size 1

Below image demonstrates the different leaves denoted by alphabets (a to h)

Q3) 37

Check the below images for better understanding, note the blue shapes fitted to indicate the square counted. 

Handle these type of questions as follows: 

1. First count the big squares (or small squares), write it down for sure, 
2. then count next lesser sized squares, write it down, and so on. 
3. Don't stick to principles like 'Symmetry', even in symmetry images, there might be squares (or any required shape) derived from the two symmetry.

Squares -> 1 (in the center) + 1x(2 - for both sides) = 3

Squares -> 9 x (2 - for both sides) = 18

Squares -> 8 x (2 - for both sides) = 16

Total squares -> 3+18+16 = 37

Q4) 13

Below image shows the alphabets considered by me

There's some mistake in this image (My mistake!), The following numbered alphabets cannot be read as capital letters -> 9,10. Alphabet numbered 9 when flipped cannot form N again. Also 10, representing S cannot assume any capital letter after flipping. But alphabet numbered 13 can be assumed to form 'S'. So, I still consider that. Thanks to Adamya Kaushik for informing this to me.

Q5) 9

Frankly speaking, I'm not that good at fonts, but tried figuring these font categories, correct me if i'm wrong

Trick is identify font alphabets with tails and without tails, then take any alphabet (say a,t,i ...) and compare with other word alphabets of the same category.

• Font 1 = spectrum, operators, farmers 
• Font 2 = auctions, performance, mango,
• Font 3 = display, total, sugar,
• Font 4 = holdings, 
• Font 5 = maximum, allegations
• Font 6 = industry, programme, benchmark, natural, utilized, contributed, cartelisation, compensation
• Font 7 = reduction, withdrawn, 
• Font 8 = emerged
• Font 9 = fiscal

Q6) Team-2, 286

My Explanation to this question is given below. However idea given by Vaishnav Hari through his comment below is very simple that I'm sharing here.

we can simply subtract max and min scores.....
(mean - min) + (max - mean) = max - min

My actual explanation

This is a statistical question, wonder how these questions are asked in UCEED exams. Anyway my explanations goes like this with the help of the below image.

The actual procedure is to find the standard deviations/variance of the given data set which requires calculator. But considering the fact that you are not given any calculator in exam, here is one more simple way.

Find the average of all the data for all teams, like for say team one, the average of given 5 data will be

mean 1 = (255+278+291+268+308)/5 = 280

Here denominator 5 represents the total no. of data considered. Likewise do that for rest teams too.

Now, find the difference between the identified mean and the maximum and minimum values of the given data for all teams. For ex, for team1,

(Mean - min value) = 280-255 = 25
(Max value - Mean) = 308-280 = 28
Sum them up which is 53.

Do this for the rest teams too, now choose the team which has the minimum sum, that is team 2

The idea is, spread or variance represents how far the data are spreaded from the mean value irrespective of the mean value. So, if the difference between the ends are less, it mean the data are less spreaded and hence less standard deviation or variance.

Hope you understood this.

How to solve this kind of broken puzzles ?

Well, it's some what tough, took some time for me to figure out the pattern. I have marked alphabets for the individual broken peices as shown in the below image

The below image shows the arranged form of the pieces with the alphabets mentioned for your better understanding. Hope this is clear.

How to solve such puzzles ?

Simple thing is identify the four pieces of the puzzles, which represent the corners. Like for example, the top right corner of the piece should have two perpendicular edges at 90 degree each to the top, right ?, similary, the bottom right corner should have a piece which has two corners 90 degree to each other. Similar logic applies to the other right extreme corners. Once you keep these four pieces in their place, it's easy to identify the pattern. You can cross check what I explained in the above image, n understand how extreme corners are alligned. I always start with the corners, It works for me! give it a try.

Q19)

Given cube is 6x6x6 sized. So, each row will have 6x6 = 36 cubes.

We will count the missing cubes from bottom to top.

Bottom (1st)  row - nill
2nd row = 1
3rd row = 7
4th row = 9
5th row = 16
6th (top) row = (36-11) = 25

So, number of cubes = 6*6*6 - (1+7+9+16+25) = 158

Explanation:
The Lion Capital of Ashoka is a sculpture of four Indian lions standing back to back ... The capital is carved out of a single block of polished sandstone,
Ellora caves are carved in living rock

Q30) D

Just note the four corner patterns of the given image as shown in the given image

Now in the rotated images of the options shown, check if the four corner squares (if rotated) are matching or not.

Option C - anticlockwise rotation of image
Option D - anticlockwise rotation (twice) of the image

Now to check if the two options are correct or not, extend the four corners to four edges, I mean now check the rest small suare pattern on the edges.
Option B has a slight mismatch and D doesn't have any mismatch.

New update

Q51) Not sure (Answer D taken from key)

Q52) D
Based on the darkness/intensity change

Q53) D
By observing the transition of colors on both sides

Q54) C

If you closely observe the given pattern of hexagonal colors, we can infere the following points

1. Color Magenta is surrounded by two dark green and one purple for sure, rest hexagonal shapes are red
2. Green colors are mostly appearing in pairs (two dark green side by side)
3. Purple is never paired wit purple.
4. Combination of two dark hexagon colors (pairs) has either two purples as their neighbors or one purple + one magenta as their neighbours and not otherwise

With the above inferences, we can deduce that the middle two hexagons are dark green and their ends are one red and one magenta.

Q55) B
Note the given circles in column format (three columns and three rows)
The color of the smaller dots in the second column are same as that of the color of the smaller dots in the third column circles and are either towards or away from each other in each row.
Also, the color of the bigger dot in the second column of a row is opposite of the color of the bigger dot in third column of the same row.

With the above inference, we can surely say that option B is the correct missing circle.

Q56) D

This question is prey simple and straight. The third image in any row is just the difference of the first and second images in the same row.

For example, first row, first column has blue diagonal line, first row second column also has diagonal column, now their difference is nil and hence third column of the same row is not having the blue diagonal line.

With this kind of understanding, we can say that for the third row also, there will not be any blue diagonal line. So, option D is correct. Got it?

Q57) D

Option A - Red, Green and brown colors are not matching with respective colors in the painting
Option B - Blue and brown colors are not matching with respective colors in the painting
Option C - Green and purple colors are not matching with respective colors in the painting


Q58) A

Observing the script given. the font 'dha' cannot have bent semi circle, taking this into account, option A or B is correct, now again in B, the bottom little extension is bent not in straight but made with spline line.
Observing 'jha' in the given script, it cannot be curved, so option A must be correct.

Q59) A

Just a quick observation will give you a clue that the letters 'Kha' and 'ta' are adjacent and mostly appear in pairs that too in the same row.
In the given space, two 'kha' are dajacent to the empty space as hown in the below picture, so in space A and B, we should expect 'ta'. Option A suits this condition.

Q60) C

The leg part at the bottom for option C is bit bulger, I mean thicker compared to other options.

Q61) C

I'm not very sure whether what i'm going to say is correct or not, but just a try.

Observe the black dots circled in red for all the three patterns. As you can see they appear in 4's. Also,  three and two dots appear together as indicated by blue lines.

Now, in the given options, C matches this kind of pattern.

Q62) B

Transaction from first pattern to second pattern happened like this.

1. First row rotated clockwise 90 degree
2. Second row rotated clockwise 90 degree
3. Third row remain as it is

Transaction from second pattern to third pattern happened like this.
1. First row rotated clockwise 90 degree
2. Second row remain as it is
3. Third row rotated clockwise 90 degree

Now, following the pattern, we can deduce the following
1. First row remain as it is
2. Second row rotates clockwise 90 degree
3. Third row rotates clockwise 90 degree

Q63) B

It's just the mirror image of the given pattern

Q64) B

The question is straight forward, all the symbols are flipped vertically, I mean they are mirrored with vertical axis.

Q65) C

Q66) A

I went in reverse direction. from the folded view to unfolded view. The first image shows the first three unfolded views.

Below image shows the next two unfolding view. Hope you understood.


Q67) B

A simple trial and error will give the following

3 X 4 = 1 2
12 X 3 = 34 + ?

Now, the question mark should be 2, which according the the comparison in the above with question, we can say option B can fit.

Q68) D
Below, I have taken first two patterns from the given 5 consequent patterns, second pattern is obtained by rotating clockwise the first pattern in two steps as shown in the picture (indicated by numbers).

The below image shows the second and third pattern, third pattern is obtained by rotating the second pattern clockwise - 3 steps as indicated by numbers

Following the same counting, we get the number of turns as

2,3,5,7,?

Now we need to fill the question mark, since all the numbers appears prime numbers, so the required number is obviously a orime number next to 7, which is 11. So, rotate the last pattern (5th pattern) 11 times clockwise. You will get D as option

Q69) D

Workplace safety signage

Q70) D
The easiest way on how we can find is based on the first two given images
First image is clearly symmetry radially. Second image is obviously the pattern of tessellation. With these two options, we can say D is the right choice. Another thing is Fibonacci series assumes spiral form as in the given picture.

Term 'Fractal' is closely related to term 'iteration' or 'factorial' as used in mathematics. It means moving/growing, or so called evolving or expanding symmetry.
For example
4! (4 factorial) = 1*2*3*4
6! (6 factorial) = 1*2*3*4*5*6

So, images that are in growing or decreasing pattern can be a form of 'Fractal image'. Below picture shows the naturally occurring fractals.

Q77) B

This is pretty simple, the cube is turnd in fixed direction
1. from 1 to 2 (as numbered in the question), rotated to right
2. from 2 to 3, rotated to top
3. from 3 to 4, rotated to bottom (same position as in step1, so next two steps should follow steps 2 and three!)
4. from 4 to 5, rotated to right (same as step1)
5. from 5 to 6, should be rotated to top (same as step2)

Be careful with the two lines alignment, in every step, the smaller and larger lines are swapping their positions, so in the last step also (which is rotated image of step5 - to top), the lines should be swaped, so option B is correct
Below image illustrates this.

Q78) B,C

Will give detailed solution to this kind of problems in a separate post.

Q79) A

Option A shows the upright position of the given object. All other options are not matching to the actual 3D object.

Q80) Option not given (i,ii,iii conclusions holds good)

statement 2 implies "Dalis  = some melted clocks + some other things 1"
statement 3 implies "Macacre works = Dalis + some other things 2"
so "Macacre works = some melted clocks +some other things 1 + some other things 2"

So, conclusion i and ii holds good. Since all surrealists are melted clocks (some Dalis are melted clocks). So, option iii also is correct.

Q81) D
straight forward question right ?

Q83) A

The shapes given in the three views are listed below. In all the three views, all sides were shown with some shape on it except right side (right to views 2). So, obviously that side should have triangle shape in it. So, options B and C are out since triangles are shown in the front/back of hut! According to the given three views, the front and back portion of the hut has either square or star on them right?. Also, option D shows square on the side rather than on the front or back, and so it is out. Now, the only remaining option is A.

The slant portion of the hut (hut roof) on the side with triangle has pentagon shape as can be seen in view 2. If you observe option A, in which the side is rotated to left, this pattern matches, also like I mentioned had we rotated the view to the left, then the backside of the hut will now be front, which has star on it. So, option A is correct.
