1)

How many triangles are there in the given picture

2)

Eight Brothers lives in an old house where there is no electricity and no computers or any any other gadget.

Brother-2: Playing Chess
Brother-3: Writing
Brother-4: making food for the family
Brother-5: sleeping and snoring
Brother-6: cleaning house
Brother-7: watering the plants

What is brother 8 doing ?

Playing chess - Game needs two players so brother-8 is playing chess with brother-2

3)

In a particular family, each boy has as many brothers as the sisters, but each girl has twice as many brothers as that of sisters.

How many numbers of siblings are there in the family?

There are 4 boys and 3 girls in the family.

Let the number of boys be 'x' and the number of girls be 'y'.
The first statement says that each boy has equal numbers of

brothers and sisters
(x - 1) = y

The second statement says that every girl has twice as many brothers as that of sisters
2 (y - 1) = x

solving above two equations will result in
p = 4.
q = 3

4)

12)

In a race of 600m X can beat Y by 60m and in a race of 500m Y can beat Z by 50m. By how many metres will X beat Z in a race of 400m?

a) 76 m
b) 74 m
c) 72 m
d) 78 m

Answer : 76 m

When X runs 600m, Y would run (600-60) = 540m
and When X runs 400 m, Y runs (540/600)×400 = 360m

When Y runs 500 m, Z runs (500-50)= 450m
and When Y runs 360 m, Z runs (450/500)×360 = 324m

i.e., When X runs 400 metre, Y runs 360 metre and Z runs 324 metre.
Hence, X beats Z by (400-324)=76 metre in a race of 400 m

13)

One of our friend from G+ wanted explanation for this ques. I have made the below picture for convenience,

18)

A boat is crossing a wide river flowing at 8 km/hr from east to west. The landing port is exactly opposite the starting point in the north bank of the river. If the boat moves at 10 km/hr towards other bank and crosses the river, what is the width of the river? (appeard in CEED 2013 paper)

a) 6 km
b) 8 km
c) 10 km
d) 1.8 km

To reach exactly opposite point of the bank from where the boat has started; the boat should move slant towards north east at 10kmph, and water is flowing at 8 kmph from east to west, now apply Pythagoras theorem to find the relative velocity which turns to be 6 kmph.

33-34)
(optional question)
In biology, the term mutualism refers to a mutually beneficial relationship between two species. The later economic theory of mutualism is based on the labour theory of value, which states that the true cost of an item is the amount of labour that was required to produce it. Hence, goods should not be sold for more than the cost of acquiring them. Mutualism is closely associated with anarchism, because its principles were set forth in the mid- nineteenth century by the French politician and philosopher Pierre-Joseph Proudhon – the first person to define himself as an “anarchist”.
The main tenets of mutualism are free association  and free credit. In a mutualist workplace, workers with different skills form an association to create a product or service. Though dependent on each other, the workers are not subordinated as in a capitalist enterprise. Mutual banks, also called credit unions, operate on the belief that free credit enables profit to be generated for the benefit of the union’s members rather than bankers.
Modern-day mutualism is sometimes described as free-market socialism. Proponents of mutualism support a free market economy, but object to capitalism because of the inequalities created by government intervention. Many mutual businesses and banking establishments exist today, espousing Proudhon’s Co-operative model.
[Use Ture, False, Cannot say for the below questions]

a) Proudhon’s economic theory of mutualism was influenced by biological mutualism.
b) Mutual banking establishments do not operate on a for-profit basis.
c) The labour theory of value is defined as: only the person who made an item should profit from its sale.

35)

Mechanization is defined as the process of using machines to perform work that had previously been performed by people. Automation, which is an extension of mechanization, is defined as the process of performing mechanical operations with minimal or no human involvement. Automation is commonly used whenever an organization faces difficulties producing a product of a consistent quality, as well as when work is monotonous or unsafe for employees.

Automation systems can be either hard or soft. Soft automation systems are adaptable, thus allowing them to perform several different functions. Hard automation systems have each machine perform one specific function. As a result, these systems are less adaptable than soft automation systems. From the information given above, it can be validly concluded that:

a) There are at least some automated systems that require considerable human involvement to perform mechanical operations
b) If an organization can consistently produce a high quality product, it is unlikely that it will use an automated system.
c) No hard automation system is more adaptable than a soft automation system.
d) Any organization that uses an automated system has found its work to be monotonous or unsafe for employees.

1. Hi Sir,
Thank you for all the resources.
Just a small doubt..I think answer of Q10 should be c and Q49 should be d.

1. Ya, Q10 is c, it was rectified earlier, Q49 should be c not d

2. Q49 answer is c

3. option d can also satisfy the shape, right?

4. Yeah,option d, too seems the correct one

5. Sir can you show us how option C is correct for Q 49 because even am getting option D as correct

2. Thank you very much

3. Can you upload information on famous books and writers ,some important math formulas and font information . Do uceed people ask about film there directors etc . Thank you very much for all this . Please reply as soon as possible as exam date is very very near

1. UCEED sample mock test paper had one question on film directors, so there are chances! but I still doubt it's importance, I guess film directors of animated movies are more important. I will upload info on books and writers at the end of UCEED Resource collection post. Some basic math formulae are already included in that post at the beginning of the post under "Math Geometry". U may chk this link

Study materials and downloadable books for UCCED preparation

2. Authors info has been updated in the above link. Scroll to the bottom of the post to find the link under 'Additional Resources'!

4. Please explain Q 48

1. I have included a picture that explains the problem (above in the question). I think it's clear now

5. sir i think answer of q 21 part b is 15

6. sir i think answer of ques 37 is a

1. A is not correct answer brother,
If it's like - six dots on the front face, and star on the right side face (unlike in the given option where star is in front face and six dots are in side face), then it would have been another option.

2. It can D as well

7. Sir could you pleas explain how cornstarch is used as a packing material ?

1. Even, I'm not sure, but I came to know about that. I also confirmed that in web. It is used as packaging material. Have to consider some unseen facts ........

2. They are not used much in india but in foreign countries they make little balls that look like thermocol and fill the box with it. The balls are even edible!

8. Shouldn't 20th question include option e also?

1. No, it is not compulsory, without any turns also we can make clips. You may check that in google images.

9. Sir the 37th one can't be B. I think it's A. Please check. Also it's option E in the 20th question also an answer?

1. It is B bro, and not A. I've already discussed that (with Ashutosh) in the above comments. Pl check that and clarify yourself.

10. Sir no offence buts think you're foldng it the wrong way. If you fold it inwards as in towards yourself then what you're saying would be true. But you're supposed to fold it away from yourself so the the patterns paper in the outside of the cube. Please check again. And really thank you for making this blog. It's so helpful :)

1. Hello Anavi,

I shldn't have included the term 'folded' - I guess. I think that is confusing. Observing the options, the question is like we need to identify the correct cube that can be oriented in any direction - not like exact folding!

In option A, if you check the position of the 6 dots, then it's shown as 3 rows and 2 columns form, right ? But if you observe the question and fold it, the dots should be like 2 rows and 3 columns, that is the biggest difference. Other than that, it should be okay to take it as answer.

Thank you anyway. I suggest you not to struggle for a single questions as it would waste your time and time is really short, better to practice more. All the best :)

11. sir in Q36 "c" is also correct

1. I think C is not correct, please check

2. sir i think c and d both will be correct

3. assuming that bottom black portion is stick to the ground, if option C is correct, then it is not possible to upright the solid, option C suits when the image is allowed to fold bottom words too!

4. If only option C is correct then why did you mention none in the answer?

12. Thank you sir.. This is really helpful, Please can you share more practice questions for uceed.

1. You can check mock tests for CEED too, they are well applicable to UCEED, Also, today I released one more mock test, please check - CEED and UCEED 2016 Mock test - 2

13. sir in q.no 1 i can see on 23 triangles plz cud u upload a solution..

14. sir shouldn't 14th be C??

15. and the last doubt of this paper sir in q.no 37 can D also be correct ...

16. Q3 cant the answer be 5 it makes sense
suppose there are three brothers(b) so if one of those boys(b1) has two brothers he must have two sisters(s) and each girl has twice as many (b) to that of (s)
so 3 boys and two girls kind of seems right to me

17. Very good blog!! Really appreciate your efforts...keep up the good work!!

What is the answer to Q 35 ?
From the information given above, it can be validly concluded that:

a) There are at least some automated systems that require considerable human involvement to perform mechanical operations
b) If an organization can consistently produce a high quality product, it is unlikely that it will use an automated system.
c) No hard automation system is more adaptable than a soft automation system.
d) Any organization that uses an automated system has found its work to be monotonous or unsafe for employees.

P.S. Thanks a lot for this blog it is helping me a lot.

1. Q1, I'm getting only 24, pl. chk,
Q37, A is not correct, if the given pattern is folded to cube and if the side with star pttern is to appear in front with side with 'X' on top, then the side with 'six dots' SHOULD be on the left side of the cube, but in option A it's shown in right side! Pl. chk

2. sir in q.no 1 i can see on 23 triangles plz cud u upload a solution..

3. q.no 37 can D also be correct??I had asked earlier also...

4. q37, yes D us also possible, thank u man, and q1 I will try in free regarding upload of sol.

7. Sir! finally, I got 24 triangles! thanx for not saying the answer right away. if you've done as such. i couldn't have solved by my own. thanx anyways :)

8. even i got 24 triangles

21. is telanagana state is considered in 29 states?????

22. Question 18, its nowhere specified time taken to cross the river, the relative speed may be 6 km/hr .the ans would be right only if it were giventhat it took 1 hr to reach other side? Isn't it

1. Ya, assuming for 1hr case, the width is the horizontal component of speed which is 6kmph

2. So since 1.8km is a multiple of six couldnt d also be an andwer??

23. Hi the answer of Q11 should be black

1. Hi, the answer is white, u can check in any color picker online.
