Among five persons A, B, P, Q and S, B is taller than only one person, and Q is taller than B and P. S is taller than Q but shorter than A. Who is the shortest of all?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → P
Join the comparisons into one chain from the tallest to the shortest. ‘Taller than only one person’ means second shortest.
S is taller than Q but shorter than A: A > S > Q
Q is taller than B and P, so B and P come after Q
B is taller than only one person, so B is fourth and that one person, P, is fifth
Order: A > S > Q > B > P, so P is the shortest
