Four people P, Q, R, and S, of different ages, make the following observations.
P — I am younger than S.
Q — I am neither the youngest nor the oldest.
R — P is older than me.
Based on these observations, the youngest person is ______.
Options:
(A) P
(B) Q
(C) R
(D) S
Official Answer Key:
C
Step-by-Step Solution & Explanation
From P: P < S (in age).
From R: R < P.
Combining: S > P > R.
From Q: Q is neither youngest nor oldest, so Q must sit at an intermediate rank and cannot be at the bottom.
The bottom of the established chain is R, and Q cannot displace it. Hence the youngest is R.
