When Mary is twice as old as Frank, then I shall be 17 years old.

But Mary was 23 when Frank was twice as old as me.

That’s what John said.

How old was John when Frank was ten?

Suppose that John is x years younger than Frank.

Hence after 17 – x years, Frank is 17 + x years old, Johns is 17, and Mary must be 23 + 17 – x or equivalently 40 – x.

But we have 40 – x= 2 (17 + x) which provides x equal to 2.

Therefore John is 8 years old when Frank is 10.
