There are two ways to solve this problem.


    1)  You may find decomposition of the number 234 into the product of two positive integer numbers 

        with the difference 5 between them  (MENTAL solution (!) )


            234 = 117*2 = 13*9*2 = 13*(9*2) = 13*18,  which is exactly what you need,


OR


    2)  you may solve the quadratic equation


            x*(x+5) = 234.


    Surely, in this way, you will get the same answer.

ANSWER. The younger, Peter, is 13 years old.
