RRB Group D Mock Test - 18 - Question 1

The ratio of the present ages of a son and his father is 1:5 and that of his mother and father is 4:5. After 2 yrs the ratio of the age of the son to that of his mother becomes 3:10. What is the present age of the father?

Detailed Solution for RRB Group D Mock Test - 18 - Question 1

Let the present age of Father, Mother and son be x years, y years and z years
Now z/x = 1/5
⇒ x = 5z
⇒ z = 1/5 x
y/x = 4/5
⇒ 4x = 5y
y = 4/5 x
After 2 years
z + 2/y + 2 = 3/10
∴ 10z + 20 = 3y + 6
10 x 1/5 x + 14 = 3 x 4/5 x
2x - 12/5 x = - 14
10x - 12x/5 = - 14
- 2x/5 = -14
x = 70/2 = 35
∴ Father present age is 35 years
