Harry is one-third as old as Ron and 8 years younger than hermione.
If the sum of their ages is 43.How old is Hermione?
~~~~~~~~~~~~~~~~ 

x = Harry's age;

3x is the Ron's age, and Hermion's age  is x+8 years.


Total age equation

    x + 3x + (x+8) = 43

        5x         = 43 - 8

        5x         =   35

         x         =   35/5 = 7.


ANSWER.  Harry is 7 years old;  Ron is 3*7 = 21 years old;  Hermoin is  7+8 = 15 years old.

Solved.
