Q.1. Read the following information carefully and answer the questions given below it.

P, Q,R,S and T are five friends.

Q is elder to T, but not as tall as R.

R is younger to P and is taller to S and T.

P is taller to S and is not the tallest, but younger than T.

S is elder to P but is shortest in the group.

Who among the following is the tallest?

In terms of age, we have T<Q, R<P, P<T, P<S, So we have: R<P<T<Q, P<S. In terms of height, Q<R, S<R, T<R, S<P. So R is the tallest.

Q.2.Read the following information carefully and answer the questions given below it.

P, Q,R,S and T are five friends.

Q is elder to T, but not as tall as R.

R is younger to P and is taller to S and T.

Who among the following is the eldest?

Which of the following pairs of students is elder to S?

QP

QR

QT

TP

Cannot be determined

In terms of age, we have T<Q, R<P, P<T, P<S, So we have: R<P<T<Q, P<S. As there is no relation between T, Q, S so it cannot be determined. So answer is option (5).

Q.3. A man is looking at a picture, in his mother's, only brother's, nephew's house. Someone walks by this man and asks, "Who are you looking at?” The man answered, "I am looking at my son's only sister's, maternal grandfather's daughter's, husband's, son's father's picture. Also, neither my wife nor I has brothers or sisters." Whose house is the man in and who is he looking at?

The man is in his own house and looking at his own picture.

Man's mother’s only brother's nephew is the man himself as man do not have any brothers or sisters. Thus, he is in his house.

Man's son's only sister = his daughter

daughter's maternal garandfather = Wife's father

maternal garandfather's daughter = His wife (as his wife do not have any brothers or sisters)

Wife's husband's son's father is himself.

Q.4. Read the following information carefully and answer the questions given below it.

A, B,C,D and E are five friends.

B is elder to E, but not as tall as C.

C is younger to A and is taller to D and E.

A is taller to D, but younger than E.

D is elder to A but is shortest in the group.

Who among the following is the eldest?

In terms of age, we have E<B, C<A, A<E, A<D,

So we have: C<A<E<B, A<D.

In terms of height, B<C, D<C, E<C, D,A. So Either B or D is the eldest.

Q.5. Ramesh decided that Poonam, her daughter, marry Rajat. Poonam refused and cried for days without eating anything. Ramesh, in order to solve this problem, decided that she should take a small marble from a bag. If Poonam takes the blue marble, she would have to marry Rajat, if she takes the red one she would not have to. Some days later, Rajat, Ramesh and Poonam were together on the lane to the castle which is paved with small blue and red marbles. Ramesh asks Rajat to take two marbles and put it in bag. Poonam saw that Rajat puts in two blue marbles. She thinks of saying this, but then most likely the procedure has to start over. Suddenly she gets a great idea. Some minutes later it is decided that Poonam does not have to marry Rajat. What did she do?

She just took out one small marble, but then immediately dropped it on the lane with all the other marbles. Then she claims that the marble she took should be the opposite of the one which is left in the bag. So since there were two blue marbles in the hat, it will be concluded in this way that she took a red marble. So Poonam fortunately does not have to marry the Rajat.

Q.6. After a long way, a truck driver ends up in front of a tunnel. He can not get through without severely damaging his truck, because the tunnel has a height of 4.00 meters, while his truck has a height of 4.01 meters.

Suddenly he gets a great idea, he immediately starts doing some thing and after 10 minutes he is back on track on the other side of the tunnel. What was the great idea of the truck driver?

The driver removed some air from the tyres.

The border of the country has a length of 1350 kilometers. If one cubic meter of stone weights about 2660 kg, how much heavier becomes the earth by building this wall?

Obviously the stones are coming from the earth; the mass of the earth of course won't change by building such a big wall.
