Harish's present age is 8 times the sum of his two sons' present ages. After 8 years, his age will be 2 times the sum of their ages. What is Harish's present age?
Correct answer
B. 32
Why
Let the present sum of sons' ages be x. Harish is 8x. After 8 years: 8x + 8 = 2(x + 16), so x = 4 and Harish is 32.
