Question

The age of a son is one third the age of his father. If the present age of father is x years, then what is the age of the son after 10 years?

Answer 1

Father's age = x years ( given )

Son's age = 1/3 of Father's age = x / 3 years

Now

$<u>After 10 years :</u>$

Son's age = ( x / 3 ) + 10

= $<b>( x + 30 ) / 10 years</b>$
