Five years ago the average age of A and B was 23 years. If today the average age of A, B and C is 27 years, what will be the age of C after 5 years?

A30 ✓ Correct

B28

C29

D32

Correct answer: (A) 30

Explanation

C will be 30 years old after 5 years.

Five years ago A + B = 2 x 23 = 46, so now A + B = 56.

Now A + B + C = 3 x 27 = 81.

C now = 81 - 56 = 25.

After 5 years C = 25 + 5 = 30.
