I have just had a very pleasant barbecue today. Its summer over here and perfect weather for it. There was a massive texan steak cooked to perfection, much drink and fruit salad to finish. All in all a very satisfying afternoon.
However one of the people invited gave us a sort of math problem to work out. Like the chicken & fox question out of the office... I have spent a good 20 minutes on it and am bored of looking at it but want to know the answer. Who better to ask than the clever people of TMO? So here goes (no doubt I will kick myself):
3 flatmates buy a TV for $300, at $100 a piece. The guy in the store says there is a special on the TV, $50 off. However he says because he told them about the special he will keep $20 for himself and give each of the flatmates $10 back. Right, so thats $250 for the TV, $20 for the sales guy and $10 for each of the flatmates. That means each flatmate has payed $90 for the TV, which comes to $270. Plus the $20 that the sales guy took. So what happened to the extra $10?

The $90 each flatmate has paid for the TV includes the $20 kickback to the guy at the store.
Your sums don't add up because you're trying to add the $20 kickback twice.
The total paid for the tv is $270 (3 x $90). This is $30 less than the marked price after the salesman has had his $20 cut from the $50 off.
