The present age of a mother is 2 years more than three times the age of her son. Three years hence, mother's age will be 8 years more than twice the age of the son. Find the present age of the mother.
Solution: Let the son's present age be x years. Then, mother's present age = (3x + 2) years.
.'. (3x + 2 + 3) = (2(x + 3) + 8)
3x+5=2x+14 => x =9.
hence, mother's present age=3x+2 = 3*9+2 = 29 years.
