Answer:

  • Mother is 29 and son is 5

==========================

Let the mother's present age is m and son's present age is s.

Set equations as per given conditions

3 years later

  • m + 3 = 4(s + 3) ⇒ m + 3 = 4s + 12 ⇒ m = 4s + 9

3 years ago

  • m - 3 = 2(s + 8) ⇒ m - 3 = 2s + 16 ⇒ m = 2s + 19

Compare the equations and solve for s

  • 4s + 9 = 2s + 19
  • 4s - 2s = 19 - 9
  • 2s = 10
  • s = 5

Find m

  • m = 4*5 + 9 = 29
