Difficulty: Easy
Correct Answer: 22 years
Explanation:
Problem restatement
Express the age difference and the “twice in two years” condition as equations and solve for the son's current age.
Given data
Concept/Approach
Substitute Father = Son + 24 into the future condition to solve for Son.
Step-by-Step calculation
(S + 24) + 2 = 2(S + 2)S + 26 = 2S + 4 ⇒ S = 22
Verification/Alternative
Present ages: Son 22, Father 46. In 2 years: 24 and 48 → father is twice the son (48 = 2×24).
Common pitfalls
Forgetting to add 2 years to both ages in the “in two years” statement.
Final Answer
22 years
