The present age of a mother is 3 times that of her daughter. 10 years ago, she was 5 times as old as her daughter. Find daughter’s present age.
A10 years
B15 years
C20 years
D25 years
Explanation
Let daughter’s age = x, mother’s = 3x. 10 years ago: 3x – 10 = 5(x – 10) => 3x – 10 = 5x – 50 => 2x = 40 => x = 20 years.
