Answer»

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
