Question 1097474

Tom is twice as old as Andy. In 4 years time the sum of the ages will be 32 years. Find Andy’s present age.
<pre>In 4 years, their ages sum to 32, so now, their ages sum to 32 - 2(4), or 32 - 8 = 24
Let Andy's be A
Then Tom's is 2A
We then get: A + 2A = 24
3A = 24
Andy, or {{{highlight_green(matrix(1,6, A, "=", 24/3, "=", 8, years-old))}}}
