A problem by Roshan Ali
The egg vendor calls on his first customer and sells half an egg . To the second customer he sells half of what he had left and half of an egg, and to the third costumer he sells half of what he had then left and half an egg. But he did not break any egg. In the end three eggs were remaining HOW MANY DID HE START OUT WITH ?
The answer is 31.

The answet is 31 eggs. Well you can start out by trying the options if you have them and 31 fits the best :- (i) 1st customer, half eggs sold 31/2 = 15.5 + half an egg = 16 eggs total, leaving 15 (31 - 16) (ii) 2nd customer, half eggs sold 15/2 = 7.5 + half an egg = 8 eggs total, leaving 7 (15 - 8) (iii) 3rd customer, half eggs sold 7/2 = 3.5 + half an egg = 4 eggs total, leaving 3 (7 - 4) But I don't know how did he sell half eggs without breaking them ?
