The sum of the present age of mother and her son is 60 years. Six years ago, the age of the mother was five times the age of her son. What will be the age of her son after 6 years?

20Yr

Let the present age of son be x.

Then, present age of mother = (60−x).

According to the question,
⇒ (60−x)−6=5(x−6)
⇒ 54−x=5x−30
⇒ 54+30=5x+x
x=14

Son's age after 6 years =14+6

= 20 years
