QUESTION OF THE DAY:

          Rana Sangha was awarded for each wound inflicted upon him in a battle. For the first wound he was awarded 1 gold mohur, for the second 2, for the third 4, for the fourth 8, and so on. Its received in total 65,535 gold mohurs. Find the number of wounds he braved?
         a)      14                                                 
         b)      15                                               
         c)      18
         d)      13                                                 
         e)      16


2^(n) -1= 65535. So 2^(n)= 65536= 2^16. So n=16.
