Answer 1

Answer:

son= 8yrs 10 months (approx.)

father=47 yrs 2 months(approx.)

Step-by-step explanation:

lets person's present age be x and son's present age be y

Given in question:

(y-4)=9(x-4)

(y+4)=4(x+4)

To calculate x and y:

y=9x-32

y=4x+12

So,

9x-32=4x+12

x=44/5= 8yrs 10 months (approx.)

y= 236/5=47 yrs 2 months(approx.)
