A simple but elegant puzzle
Five friends at the gym came upon the new weighing machine recently installed there. They decided to take their weights in pairs (two at a time). The five of them can have ten pairings. They found the weights to be 259, 251, 264, 281, 268, 242, 257, 266, 253 and 275 pounds.
From this can you find out what were the individual weights of the friends?
