As Q, S, T, U and V don’t work with

NASA, R has to work with NASA and he

doesn’t belong to France. And as WHO-

UK, UN-China, these two combinations

are fixed, these two combinations have

to go with either T or V. But as V doesn’t

belong to UK, V works with UN and

belongs to China. And thus T works with

WHO and belongs to UK. Thus S belongs

to France, R belongs to Russia and P

belongs to Canada. And Q works with

OPEC and U works with WB. Thus the

final arrangement is as below:

8. Ans. A.

So we have given this-

Three boys are sitting between two girls.

The only boy who is not among those

boys is sitting at one of the extreme

ends. Not more than two girls are sitting

together. So we have these possibilities.

Case 1:

Case 2:

Take Case 1:

H is sitting fourth to the left of L. L can

be sits at 6th or 7th.

If L sits at 6th then H sits at 2nd but H is

a boy and at 2nd position a girl is sitting

so this cannot be possible.

So L sits at 7th and H sits at 4th. G is

sitting between H and F. So G must be

sits at 4th and F at 5th. E is the only boy

left so he must be sit at 8th. J is not the

immediate neighbor of L. J doesn't sit at

any of the extreme ends. So J must sit

at 2nd. Both J and K are sitting beside a

boy. So K must sits at 6th. At 1st position

I sit. So this is a valid case we do not

need to check another.

Final arrangement is like this-

9. Ans. B.

the one who is shortest. D must live on

6th floor.

● One person lives between D and the

one whose height is 180cm. So the one

whose height is 180cm lives on 4th floor.

● G’s height is 178cm and lives just

above E. One person lives between E

and A and E lives above A. So G must

live on 5th floor, E lives on 4th floor and A

● Not more than two persons are shorter

than E So E’s height cannot be more

than 170cm so this case gets rejected.
