**1)**

The situation is given in the below picture. H stands for home, M for market, s for school, PO for post office.

It's given in the question that when Alakananda travels exactly north from Market, she reaches Home, and it's also given that walking from school exactly in east 37km, will end up at Market. and from market, if she move towards east, she will reach to Post office. So, School, Market and Post office should lie on the same straight line.

According to the triangle formed by SHM, applying Pythagoras theorem

x = sqrt(37^2 - 35^2)

You don't even need calculator to solve this, just apply (a^2 - b^2) formula, which is equal to (a+b)(a-b)

so,

x = sqrt((37+35)(37-35))

= sqrt(72*2) = sqrt(144) = 12

Now, according to the triangle formed by H-M-PO, applying Pythagoras theorem

y = sqrt(13^2 - x^2)

y = sqrt(13^2 - 12^2) = 5

So, distance from school to Post office = 35+y = 40

**2)**

The below shown picture illustrates the situation for 6X6X6 cube. Cubes which are in edges (other than the corners) will have red color on their two faces.

Consider the front face, if we were to cut the cube into small cubes of 1X1X1 shapes, then we need to make cuts as indicated by the straight lines (other than the edges) shown in the above explanatory image. For the given cube of size 6*6*6, we need to make 5*5*5. If we do so, then the individual cubes that are marked with symbols (as shown in the above examples for front side and side1) will have two surfaces with red.

So, counting the total number of cubes on corners/edges (which is 8+8+6+6 = 28 for a single side - for the present case of 8*8*8 cube) and subtracting 8 (removing 8 corners which has red color on three surfaces) will give the answer

i.e

(28+28+12+12)-8 = 72 cubes

**3)**

The given solid is symmetry but it has slant shapes, so should be careful while counting.

__Try this way -__

Avoid counting the slant surfaces (rectangles in the given picture) and count the rest shapes as I have given (front-right-back-R-Top-bottom).

After this, count the slant surfaces separately.

From front (excluding slanting rectangles) -

1 small square + four triangles = 5 surfaces

The picture is symmetry, so from all sides, the same count will come, i.e

1 small square + four triangles = 5 surfaces

So, since we have to count fro six sides, so total surfaces (excluding slant rectangles) = 5*6 = 30

Now, separately count the slant rectangles - which will be 12 (be careful while counting this). So, total = 30+12 = 42

You may check the above image to get a clear understanding of the explanation.

**4)**

**Answer :**

**75**

This question is also based on observation. Since the geometry is symmetry, we can take a quarter of the symmetrical shape, and count the number of cubes, and multiply that by 4. Be careful while counting the central cubes. Better if you count them separately!

**6)**

M (all) ---> F (all) ---> D

M (all) ----------------> D

So, all Mammals are dolphins

Also, since all mammals are fish, obviously part of the fish are mammals, so Option A is also correct, B is wrong, straight forward. C is also logically correct.

This question is also based on your observation, anyway here's a simple procedure or way of observing the image.

In the given picture, assume two arrows diagonally (indicated in red). Now; note the shapes at the corners - for example one is semi rectangle. and the shape in opposite side is say triangle. Now only consider the yellow arrows, which are exactly opposite. Note the shapes - semi circle and gun shape, now observe all the options which have this pattern.

Also, don't forget the shape of the center black rectangle as per the rotated orientation of the options.

As shown in the figure, consider the first image with black face on the top and red face on the front. Now, we want the color of the surface on the opposite side of the black surface. So, tilt/turn the cube in such a way that black surface is moved to the back position as shown in the next image of the below picture. I mean turn the cube clockwise. Now, red face is on the top, while green surface is still on the right side of the cube view. Now check the options with this configuration, only last picture in the question matches. So, it's yellow color !

If you were asked to find different color - other than yellow, do the above procedure and orient the cube such that it matches color arrangements as in any one of the option given to you.

Answer :

Split the combinatorial words into two parts as shown below

wigges + slorm -----------> flat + pen

widdle+ brap -------------> round + nib

slorm + wiggel ------------> pen + ink

from this we can conclude that

wigges ---> flat

slorm -----> pen

brap ------> nib

wiggel -----> ink

now we want to find 'nibstore' = nib + store = brap + ........(something)

option a) brap+dansa

option d) brap + wiggel ( which is brap+ink ....... incorrect)

so option

As shown in the figure, consider the first image with black face on the top and red face on the front. Now, we want the color of the surface on the opposite side of the black surface. So, tilt/turn the cube in such a way that black surface is moved to the back position as shown in the next image of the below picture. I mean turn the cube clockwise. Now, red face is on the top, while green surface is still on the right side of the cube view. Now check the options with this configuration, only last picture in the question matches.

Split the combinatorial words into two parts as shown below

wigges + slorm -----------> flat + pen

widdle

so option

**a**should be the answer.

**18)**

Answer :

**c**

This problem can be solved using your imagination/observation. Anyway as usual let me give one possible method

**Method**

Figure shows one possible shape of the nib which can draw as shown in the question. Remember Indians have the habit of drawing from left to right. And the given straight line is projected towards left. So, the nib should also project towards left as I showed in the picture.

Now, if you are to draw a circle, you will obviously start from the top and move in anti clockwise direction as shown in the image (b). Now, if you use the given nib, ans start drawing a circle, then you have to expect a sharp line (instead of broad width line) at the place where the nib moves parallely in the direction of the nib angle. To make it simple, if you assume tangent lines, drawn over the circle (b) as shown in (c)then the location on the circle at which the tangent angle is same as the nib angle is where the line will not be thick, got it ?

So, using this logic, option C is the answer.

**Answer :**

**a**

The below picture helps in better understanding, although I used lines (with diff. colors) to extend and show where they meet. Clearly, red extended lines are out of perspective while others are able to meet at a vanishing point. Although I used coloured lines for your explanation, but you need to imagine and visualize this while in exam.

**31)**

Answer:

**a**

I initially got confused a bit with this question. They mentioned that the arm has to be turned toward us. If we assume that that arm is of some one else in the screen and has to be turned toward us (which means outside of the screen and towards us), then option A is not the answer. But according to the answer key and Option A being the answer, we can say that the image shown has to be assumed as our own arm, and moving toward us means moving away from the screen. In this case option A is the answer.

The reason is when the arm moves away from us, then hands with fingers will look smaller in size compared to the arm/upper limb since they are near to the scene of capture. Things that are near to the camera should appear bigger in size compared to farther objects. Also notice the fold shown near elbow.

**32)**

**Answer:**

**d**

**No matter what distance the person moves, his height will be same, to find the mid point, use the concept of maths! That is the point of diagonal is always at the mid, like for the example of a diagonal shown below**

So, if you draw two diagonal lines, then the contact point is obviously the mid path! as shown in the figure

**33)**

If you observe the middle shape (stick human figure), then he is not at the maximum height nor is falling down (In terms of physics - he is in the travel of ascent). In other words, he is moving away from earth (against the gravity) ans so the air will try to push hum down. It also tries to push his cape to the down. So, it's almost vertically downward - Option A matches.

If he were to jump from top, or he is falling down, then the air will again try to oppose him in opposite direction to his travel, In other words towards up. So, the direction of the cape should also be vertical (In actual, the direction would most probably be in the curve (parabola) of the travel/path.

Figure clearly explains the situation. Like in the above questions, use the principle of numbering system. Now, identify the projections and mark them as I did in the picture - Porjecion 1, proj 2, proj 3

Now, check the options that have depressions at the same location as projections are in the given question. Option C matches as shown in the picture.

Answer:

In thermal engineering terms, that's a combination of conduction and convection heat transfer process. Heat from outside as well as from inside will be taken by the wet sand (between the two pots) and since sand has greater pores and is not compact, there will be minute spaces through which air can easily flow. This air will come in contact with the wet sand and will take away the heat by evaporating. Thus the water inside will not be affected by heat outside, which is one best way of natural cooling that is practiced in India too !

Answer:

**35)**

**36)**

Answer :

The below picture helps you with explanation.

As can be seen, if the top portion is circular (just like a pipe), then the front view will be as shown in the left most image above. Both the cone circular section and the pipe circular section matches horizontally and so appears like a line in front view. But if instead the pipe is rectangular in shape, then as shown in the third (right most) image above, the extra projections (denoted by A,B,C,D) are over-fit at the intersection ad their radius is greater compared to the radius of a circle inscribed inside the square/rectangle. So, it projects and hence extends downwards in the top view with sharp edges as shown in option A. Hope you got it!

(By observation)

**38)**

It can be solved by visual observation without any hand work. If you are not able to do so, then follow the following method

**Method :**

Give numbering to the three rectangular projections of the given image. Three projections are there, so three numbers, follow either clockwise or anticlockwise numbering system.

Start from a reference side, say right side of the given question. Remember this reference. Now, take all the options (one by one) and try to follow the same numbering system in the same direction as done to the question. Identify where the reference side is and start from there. Visually check the distance between the number sequence in the assumed direction. If it's in correct order, then list those options.

Now check the size of the projections at each numbered mark. If it matches at all numbers, then that would be the answer. Only last option is matching

ReplyDeleteHi, this is really very helpful.

ReplyDeleteBut can you please explain me the 36th question?

I think B option should be the answer of question 37 as in the image, first block corners are touching the sides of the block beneath it and option B shows the same figure if someone watches it from top which clearly signifies that that the B option is correct not the C option.

ReplyDeleteThey are following a particular sequence that is the extruded part of 3rd block is little less than that of 2nd, extruded part of 4th is less than that of 3rd and 5th block is exactly touching the edges of 4th block hence the 6th box has to be inside 5th block. They are asking about 6th block read the question properly

Good day sir.

ReplyDeleteCouldn't really get the question 2.

Since the cube was 8x8x8, I eliminated the corners and arrived at a cube that is 6x6x6 which clearly lies within the 8x8x8 cube framework. hence I just solved for one face ie 6x6 =36 cubes on one face that have exactly one face colored and later for 6 sides getting 216. where am I going wrong. please explain. sincerely asking. I might be trying to do it quick and making a blunder but I really need an explanation.
