Answer :

Alan is 14. James is twice as young, meaning two times as young as his brother.

14/2 = 7

So, 7 is two times younger than Alan, who is twice as old as James.

James is 7 years old.
If Alan is 2 times as old as James, that mean James' age is 1/2 that of Alan. Alan is 14, so James is 14 divided by 2, or 7 years old.
