Check what the result would have been if Minakshi had chosen the numbers shown below. In each case keep a record of the quotient obtained at the end.
1. 132Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Chosen number = 132
                           Reversed number = 231
                                    Difference = 231 - 132
                                                   = 99
We have                         99 + 99 = 1, remainder = 0
2. 469                      Chosen number = 469
                             Reversed number = 964
                                      Difference = 964 - 469 = 495
We have                          495 + 99 = 5, remainder = 0
3.                            Chosen number = 737
                            Reversed number = 737
                         We have dirrerence = 737 - 737 = 0
                                             0 + 99 = 0, remainder = 0
4.                             Chosen number  = 901
                              Reversed number = 109
                                       Differende = 901 - 109
                                                      = 792
        We have              792 + 99 = 8, remainder = 0

Check what the result would have been if sundaram had chosen the numbers shown below. 1. 27Â 2. 39Â 3. 64Â 4. 17
1.                     Chosen number = 27
        Number with reversed digits = 72
           Sum of the two numbers = 27 + 72 = 99
Now,                                  99 = 11[9]
                                             = 11[2 + 7]
                                             = 11(Sum of the digits of the chosen number)
2.                        Chosen number = 39
           Number with reversed digits = 93
               Sum of the two numbers = 39 + 93 = 132
Now,                            132 + 11 = 12
i,e,                   132 = 11[12]
