Check what result would have been if Sundaram had chosen the numbers shown. 1.17 2.21 3.96 4.37.

Solution

1.                           Chosen number = 17
             Number with reversed digits = 71
                                    Difference = 71 - 17 = 54
                                                   = 9 x [6]

2.                              Chosen number = 21
                       Number with reversed digits = 12
                                             Difference = 21 - 12 = 9
                                                            = 9 x [1]
           = 9 x [Difference between the digits of the chosen number (2 - 1 = 1)]

3.                      Chosen number = 96
         Number with reversed digits = 69
                               Difference = 96 - 69 = 27
                                              = 9 x [3]
= 9 x [Difference between the digits of the chosen number (9 - 6)]

4.                                  Chosen number = 37
                    Number with reversed digits = 73
                                            Difference = 73 - 37 = 36
                                                          = 9 x [4]
      = 9 x [Difference between the digits of the chosen number (7 - 3 = 4)]
