Me too (Question: 95334.0 )

Mera be

Question:
The ratio between the ages of a father and a son at present is 5: 2 respectively. Four years hence the ratio between the ages of the son and his mother will be 1: 2 respectively. What is the ratio between the present ages of the father and the mother respectively?
Options:
A) 3:4
B) 5:4
C) 4:3
D) Can’t be determined
Solution:

Ans:(d)

Let the present ages of father and son be ‘5x’ and ‘2x’ years respectively.

After 4 years, Son’s age = (2x + 4) years 

According to question 

After 4 years


Ratio between the present age of the father and mother = 5x: (4x + 4)

∴ We cannot find the exact value of ratio.
