I have an easy brain bender: I have money in my pocket and there are three stores I want to enter. When I enter Store A I must pay P1.00 as entrance fee, then I could only spend half of the money I have left then before leaving that store, I must pay another P1.00 for exit. The same goes when I enter Store B and C. The question is upon leaving Store C and paying the exit fee of P1.00 which happens to be the last money I have, how much money do I have before entering Store A? The first one to get the answer right receives $0.3.
