There are 1000 soliders with a number on their T Shirts (1,2,3…..999,1000) standing on a circular track. Man with No.1 is carrying a sword in his hand. He kills man at No. 2 and pass on sword to No. 3. Man with No.3 kills man at No.4 and pass on to No.5. This goes on until we have only one solider on the track.
What will be the No. on his T-Shirt?
