Question

raja mother is four times old as raja. After 5 years his mother will be three times as old as he will be then. find their present age.​

Answer 1

Step-by-step explanation:

let raja's age be y,

and her mother's age be x

x=4y

After 5 years,

x+5=(y+5)3

x+5=3y+15

x-3y=10

substitute value of x (x=4y)

4y - 3y = 10

y = 10

x = 40

Raja's age is 10 years and

her mother's age is 40 years
