Difficulty: Easy
Correct Answer: 41 years
Explanation:
Introduction / Context:A direct “years ago” ratio with one current age given. We work backward to the past and then forward for the other person's present age.
Given Data / Assumptions:
Concept / Approach:Compute past ages first, use the ratio to get Vikas's past age, then add the elapsed time to get his present age.
Step-by-Step Solution:
Vinay 5 years ago = 17 − 5 = 1212 = (1/3) × (Vikas 5 years ago) ⇒ Vikas 5 years ago = 36Therefore Vikas now = 36 + 5 = 41Verification / Alternative check:
Check: 5 years ago 41 − 5 = 36; Vinay 12 ⇒ 12 is one-third of 36 ✓Why Other Options Are Wrong:
Common Pitfalls:Forgetting to add the elapsed 5 years back after using the past ratio; confusing one-third with one-fourth or other fractions.
Final Answer:41 years
