Answer:
javed age is 45 years and son age is 15 years
Step-by-step explanation:
let father age is x
and son age is y
so according to question
x =3y or x-3y =0 (i)
after 5 years x+5 = (y+5)*5/2
x + 5 = ( x /3 + 5 ) *5/2 (as y = x/3)
x + 5 = ( x + 15 ) * 5/6
6 x + 30 = 5 x + 75
6x -5x = 45
x =45 years
y = 15 years
