Question

Radha's age is three time his son's age. Ten years age he was five time his son's age. find their present age ​

Answer 1

Answer:

let Radha's age be x and son's age be y

according to first condition,

x = 3y

x - 3y = 0 .........(1)

according to second condition,

x -10 = 5(y - 10)

x -10 = 5y - 50

x - 5y = -40 .........(2)

subtracting equation (2) from (1)

0 + 2y = 40

y = 20

put y = 20 in equation (1)

x - 3y = 0

x - 3 x 20 = 0

x - 60 = 0

x = 60

Radha's present age is 60 yrs and his son's present age is 20 yrs
