• When u reverse the digits of age of father u will get the age of son.
  10x + y = father's age
  10y + x = son's age

  one year ago the age of father was twice that of son's age.
  10x + y - 1 = 2(10y + x - 1)
  10x + y - 1 = 20y + 2x - 2
  10x - 2x = 20y - y - 2 + 1
  
  8x = 19y - 1
  x = 19%2F8y - 1%2F8
  Only one set of single digit integers will satisfy this equation
  y = 3; x = 7
