Q28

let the age of father be 'x'

let the age of two children be 'y'

A.T.Q

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

After 5 years

x+5=2(y+5+5)

x+5=2(y+10)

3y+5=2y+20...….....from (1)

3y-2y=20-5

y=15

put y in equation no. 1

x=3(15)

x=45

So, the age of father is 45 years

the age of the two sons is 15 years
