Answer:

  • 8 years old

--------------

Let the age of the mother be x and twins be y.

Set up two equations as per information given:

  • 1) x - y = 33, (age relation now)
  • 2) x + 3 = 2(y + 3 + y + 3)   (relation in 3 years time)

Simplify the second equation and substitute x = y + 33:

  • x + 3 = 2(2y + 6)
  • x + 3 = 4y + 12
  • y + 33 + 3 = 4y + 12
  • y + 36 = 4y + 12
  • 4y - y = 36 - 12
  • 3y = 24
  • y = 8

The twins are 8 now.
