Ten years ago, the father was three times the age of his kid. In ten years, the father will be double the age of his kid. Their current ages are distributed as follows:
A. 5 : 2 B. 7 : 3 C. 9 : 2 D. 13 : 4
Explanation: Let's say the father and kid were 3x and x years old 10 years ago.As a result, (3x + 10) + 10 = 2[(x + 10) + 10 .2x+40 = 3x + 20.x equals 20.The required ratio is (3x + 10):(x + 10) = 70:30 = 7:3.
