Question 70

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?

Solution

Let Age of the son = s

$$=$$> Age of the father = 3s

GIven Product of their ages = 432

$$=$$> 3s $$\times\ $$ s = 432

3$$s^2$$ = 432

$$s^2$$ = 144

s = 12

Sum of their Ages = s+3s

= 4s

= 4$$\times\ $$12

= 48 years
