Which of the following pairs is sitting at each of the extreme end ?

• B. QS
• C. QU
• D. PQ

Answer 1

Answer:

D. PQ

Solution:

P, Q, R, S, T, U and V are sitting on a wall in a straight row, and all of them are facing north.

1. Q is at one of the extreme end and has T as his immediate neighbour.

2. V is the immediate neighbour of T and U.

3. S is sitting third from the extreme right end.

The above condition cannot be satisfied in Case I, so it is eliminated.

4. R is on the immediate right of S.

P, the only person left will occupy the vacant position.

Clearly, PQ is sitting at each of the extreme end.

Hence, ‘PQ’ is the correct answer.
