A common joke from childhood, happens in real life

When I was a kid, I heard of a joke, where a neighbourhood shopkeeper announces a sale of 50% off, the next door guy to up his ante, announces 60% off, and this goes on, till the other guy announces a 100% off, well this was all a joke, if you dont' remember it, maybe one day I can tell it to you, but the picture below caught my attention



What simple magic tells me in case of 150% is, you go pay Rs. 975 for the book, and they will give you back 975 * 1.5 = 1462.5 and a copy of the book.. WOW.. now this really is a joke.. I know it is nothing to spread on SMS, but it's worth it, to know more click here
