age. Find present age.​

Answer 1

Answer:

let, age if ashwini be x,

and age of his son be y

given, x=3y

x-3y=0 ----1

x-10=5(y-10)

x-10=5y-50

x-5y=-40 -----2

subtract 1 from 2

(x-5y) -(x-3y) =-40-0

x-5y-x+3y=-40

-2y=-40

-2y=-40

y=20

from 1

x-3(20)=0

x= 60

therefore age of ashwini is 60

age of his son is 20
