Question

the ratio of the present ages of mother and son is 12:5 the mothers age at the time of the birth of the sun was 21 years find their present ages

Answer 1

"Let us take the age of mother to be 12x

Age of son will be 5x

Already mother age at the time of son birth is 21 years

Therefore, the age of Son 5x = 21

x=21/5

Mother age = 12x = (12 * 21)/5 = 50.4

So the age of the mother is 50.4 years.

Let's find the age of the Son:

Mothers age 12X = 20 => X = 20/12

We already know, son = 5X = (5*20)/12

son age = 8.33 years"
