UPSC CAPF – 2012
The correct option is C, indicating Z will have the central position.
We are given a set of comparative statements about the richness of five individuals: X, Y, Z, P, and Q. We need to establish the relative order of their richness and find the person in the middle position.
The given statements are:
1. X is richer than Y (Y < X) 2. Z is richer than X (X < Z) Combining statements 1 and 2: Y < X < Z. 3. P is richer than Z (Z < P) Combining with the previous order: Y < X < Z < P. 4. Q is the richest of all. This means Q is richer than P, and therefore richer than everyone else. Adding Q to the order: Y < X < Z < P < Q. There are 5 individuals in the order of increasing richness: Y, X, Z, P, Q. In a list of 5 items, the central position is the 3rd position. In the order Y < X < Z < P < Q, the person in the 3rd position is Z.
