There are 40 seats in a bus. People agree to share the money for the number of seats. The total money comes to 70.37. How many seats were free?

• 9 seats are free
  as 70.37 = 31*2.27

• It is based on divisibility of a number.
  Here 70.37 is the total fare of occupied seats.
  So we have 2 find out the occupied seats.
  Divide 70.37 by 31 as it is not divisible by other numbers like 39,38,37..... and other possible numbers within 40 with less decimal points.
  So 70.37/31 will be 2.27 which is the rate per seat.
  So no: of free seats come to 40-31=9
