Three friends went to buy 3 toys of 20 rupees each. Since they bought 3 pieces, the shopkeeper decided to give a discount of 5 rupees. He sent back 5/- through his servant to be given to the 3 friends. For easy division among the frends, the servant secretely put 2 rupees in his pocket and gave 1 rupee each to 3 of them as the discount. Thus, a toy for each of them cost 20-1 = 19. Total cost for 3 toys comes: 19 x 3 = 57. The servant has 2 rupees in his pocket. 57 + 2 = 59. But they had spent 60/- (20 x 3) for the 3 toys in the beginning, but here the calculation comes only to 59/- (i.e. 19x3= 57 + 2(servant's pocket). Where is the 1 rupee gone ???
