Each of the questions below consists of a question and two statements numbered I and H are given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and –
Seven people- P, Q, R, S, T, W and X- are sitting in a straight line facing north but not necessarily in the same order. How many people sit to the right of P?
I. R sits at one of the extreme ends of the line. T has as many people sitting on his right, as to his left.
II. S sits third to the left of X. Q sits to the immediate left of W. Q does not sit at any of the extreme ends of the line.
Clearly, I alone and II alone are insufficient as there is no data about P.
I & II : R sits at one of the extreme ends while Q does not.
T sits in the middle while QW are adjacent in that order.
S sits third to the left of X, => S __ __ X
The only possible pattern is : R S P T X Q W
=> There are 4 people to the right of P.
Thus, I & II together are sufficient.
