Bah! Am I Santa Claus?
:P
This is a basic maths riddle that baffled me for years when I was young (my mum would never tell me the answer):
A woman selling eggs stops at a house, where the occupant says "I'll have half your eggs, plus half an egg, and I don't want any broken ones". She stops at another 4 houses where the request is the same: "I'll have half your eggs plus half an egg, and I don't want any broken ones". After the fifth house, she has sold all her eggs and not sold any broken ones. How many eggs did she start with?
