Question

a father is 30 years old than his son .in 12 years , the man and will be three times as old as his son. find their percentagr

Answer 1

First,
$30 + 12 = 42 \\ 42 \div 3 = 14$
Hence, after 12 years, Father = 42 years
Son = 14 years
Now,
Before 12 years (present), Father = 42-12 = 30 years old
Son = 14-12 = 2 years old.
