Instructions

Study the following information carefully and answer the questions given below :
Ten people are sitting in two parallel rows containing five people each, in such a way that there is an equal distance between adjacent people. In Row- 1, Q, R, S, T and U are seated and all of them are facing north. In Row - 2, L, M, N, O and P are seated and all of them are facing south. Therefore in the given sitting arrangement each member seated in a row faces another member of the other row. S is sitting second to the left of R. R is not sitting at any of the ends of the line. There are two persons between P and L. The person who faces T is to the immediate left of M. M is sitting at the extreme right end. R is an immediate neighbour of U. The person who faces U is an immediate neighbour of both P and N.

Question 145

# Who among the following is not seated at any extreme end of Row - 1 and Row 2 ?

Solution

S is sitting second to the left of R and R is not sitting at any of the ends. From these two sentences, there are two possibilities as shown.

_ _ _ _ _                     _ _ _ _ _

_ S _ R _                     S _ R _ _

Case - 1                      Case - 2

The person who faces T is to the immediate left of M. M is sitting at the extreme right end. This implies that M should sit at the extreme right and T should be sitting beside S. Hence, Case 1 is ruled out. Now the arrangement looks like this,

M _ _ _ _

S T _ R _

R is an immediate neighbour of U. The person who faces U is an immediate neighbour of both P and N. There are two persons between P and L. The remaining position will be occupied by Q. Final arrangement will be as shown below,

M L N O P

S T R U Q

M, P, S, Q are sitting at extreme ends. Hence option e is the correct answer.
