Save

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 - 13 - 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

The average age of a class is 15.8 yrs.The average age of the boys in the class is 16.4 yrs while that of the girls is 15.4 yrs. What is the ratio of the girls in the class?
Detailed Solution for RRB Group D Mock Test - 13 - Question 4

Let the ratio be a : b
Total no. of boys = 16.4a
Total no. of girls = 15.4b
Total no. of students
= 16.4a + 15.4b
Average age of boys = 15.8a
Average age of girls = 15.8b
16.4a + 15.4b = 15.8a + 15.8b
0.6a = 0.4b
⇒ a/b = 0.4/0.6 = 2/3
