The ratio of the age of a father and his sonis 3 : 1. If the product of their ages is 432, then whatis the sum oftheir ages?
Let  Age of the son = s
$$=$$> Â Age of the father = 3s
GIven Product of their ages = 432
$$=$$>     3s $$\times\ $$ s = 432
           3$$s^2$$ = 432
           $$s^2$$ = 144  Â
             s = 12
Sum of their Ages = s+3s
                 = 4s
                = 4$$\times\ $$12
                 = 48 years
