23.   Rich and poor

      A newspaper printed this information about the world’s population.

                            If the world was a village of 100 people,

                            6 people would have 59% of the total wealth.

                            The other 94 people would have the rest.

      On average, how many times as wealthy as one of the other 94 people would one
      of these 6 people be?

      The pupil said:


                          So, to the nearest per cent, 2 must be 34%
