Answer 2

Answer:

Step-by-step explanation:

let father's age be x and son's age be y presently

∴ 4 years ago

father= x-4    ;     son= y-4

⇒ATQ,  (x-4)=4(y-4)

          ⇒ x-4=4y-16

           ⇒ x-4y+12=0     .........(i)

Also, presently

            ⇒ x + y = 53    

            ⇒x + y - 53 = 0       ..........(ii)        

(i)-(ii)   ,             -5y + 65 = 0

                          y=13

                        ⇒x= 40

therefore father is 40 and son is 13
