B Correct answer
Explanation

Sum of ages (H+W+C) 3 years ago = 27 * 3 = 81. Present sum = 81 + 9 = 90. Sum of ages (W+C) 5 years ago = 20 * 2 = 40. Present sum (W+C) = 40 + 10 = 50. Husband's age = 90 - 50 = 40.

AI explanation

The average age of the husband, wife, and child 3 years ago was 27 years, so their combined age 3 years ago was 81 years. Their total present age is 81 + 9 = 90 years. The average age of the wife and child 5 years ago was 20 years, making their combined age 5 years ago 40 years and their combined present age 40 + 10 = 50 years. The husband's present age is therefore 90 - 50 = 40 years.
