Difficulty: Easy
Correct Answer: 24 years
Explanation:
Introduction / Context:The statement “Jayesh is as much younger than Anil as he is older than Prasant” means Jayesh’s age lies exactly midway between Anil’s and Prasant’s ages. We use the midpoint idea with the given sum to compute Jayesh’s age.
Given Data / Assumptions:
Concept / Approach:From A − J = J − P we get J = (A + P)/2. With A + P known, compute J directly.
Step-by-Step Solution:
Given A − J = J − P ⇒ 2J = A + P.A + P = 48 ⇒ 2J = 48 ⇒ J = 24.Verification / Alternative check:
Pick A = 30, P = 18 (sum 48). Then J = 24 satisfies A − J = 6 and J − P = 6.Why Other Options Are Wrong:
20 or 30 contradict the midpoint requirement for sum 48.“Cannot be determined” is incorrect since data suffice.Common Pitfalls:
Treating J as the difference or another ratio rather than the average.Ignoring that the sum directly pins J.Final Answer:24 years
