A father is twice as old as his son 20 years ago the age of the father was 12 times the age of the son. The present age of the father is:

  • (A) 44 years
  • (B) 32 years
  • (C) 22 years
  • (D) 50 years
  • Solution: Let son’s present age = x
  • Then father’s present age = 2x
  • 20 years ago:
  • Father = 2x - 20, Son = x - 20
  • Given:
  • 2x - 20 = 12(x - 20)
  • 2x - 20 = 12x - 240
  • 220 = 10x ⇒ x = 22
  • Father’s present age = 2x = 44
