Check what the result would have been if sundaram had chosen the numbers shown below. 1. 27 2. 39 3. 64 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]
                                           = 11 [ 3 + 9]
                                           = 11 [ Sum of the digits of the chosen number]            

3.                                     Chosen number = 64
                       Number with reversed digits  = 46
                                                    Sum   = 64 + 46 = 110
Now,                                                110 = 11[10]
                                                            = 11[6 + 4]
                                                 = 11[ Sum of the digits of the chosen number  
4.                                      Chosen number    =  17
                        Number with reversed digits     = 71
                                                        Sum   =  17 + 71 = 88
Now,                                                    88    = 11[8]
                                                                 = 11[1+7]
                                                   = 11[Sum of the digits of the chosen number]
