Question

The ratio of a father's salary to his son's salary is 3:2 , whereas the ratio of the son's salary to his mother's is 4:5 . If the mother earns Rs . 45,000, calculate the salary of the father. ​​

Answer 1

Step-by-step explanation:

Let father age is 7x

And son age is 2x then after 15 year father age is 7x + 15

After 15 year son age is 2x + 15

7x+15 2x+15 2÷1

> 4x + 30 = 7x + 15

4x – 7x = 15 – 30

> -3x = -15 x = 5

Hence father present age=7 x 5 = 35

Son present age=2 x 5 = 10 difference of father and son age=35 -

10 = 25

So father age was 25 years when son was born
