Question

Problem: One-half of Alvin's age two years from now plus one-third of his age three years ago

is twenty years. How old is he now?

Answer 1

24.

Explanation:

Let's make the answer a variable, alright?

20 = (x - 3)/3 + 3(x + 2)

Get rid of the fractions.

120 = 2(x-3) + 3(x + 2)

120 = 2x - 6 + 3x + 6

120 = 5x

x = 24.

24 is your answer.
