• (10x + y)(10a + b) = 1148 = (10y+x)(10b+a)
  => 99(ax -- by) = 0
  => ax = by where a, b, x, y all are < 10.
  from given answers we get ax = by in the pair 14, 82 we have
  14x82 = 1148 = 41x28 so
  price is 14, number sold is 82
  when reversed digits
  price is 41 and number sold is 28 which is
  82 -- 28 = 54 less.
