The ratio of the present age of father to that of his son is 7.2. After 5​

Answer 1

1. Answer:

let the age of ram be x

age of mohan = 55-x

before 10 years, age of ram= x-10

and age of mohan= (55 - x) - 10

According to question,

x-10: (55-x)-10=4:3

x-10/55-x-10 = 4(55-x-10)

3x-30=220-4x-40

3x-30=180-4x

3x+4x=180+30

7x=210

x=210/7

x=30

therefore age of ram= 30

and age of mohan=20
