Answer :

Let the age of son be x and age of father be y.

Since father is 30 years older than his son


Therefore, father’s age = y = x + 30 ……(1)


After 12 years


Son’s age = x + 12


Father’s age = x + 30 + 12


= x + 42


After 12 years the man will be 3 times as old as his son


Therefore, father’s age = x + 42 = 3(x + 12)


x + 42 = 3x + 36


42 – 36 = 3x – x


6 = 2x


x = 3


Put in (1)


y = 3 + 30


y = 33


Therefore, son’s age is 3 years and father’s age is 33 years.
