Two boys went to a book shop and purchased a book which costs $50. They paid $25 each for the book and left the store. When the store manager went to the cashier, he found that they have taken $5 extra from them. So, the actual cost of the book was $45. The manager gave $5 to a worker out there to return it to those boys. Let's make it more interesting, the worker was a bit greedy, he took $2 from it and returned $3 to the boys. They distributed $1.5 and $1.5 each and thought that they have paid $25 - $1.5 = $23.5 each for the book. Here comes the problem, Now, we all (I mean those who are reading this thread) know that the boys paid $23.5 + $23.5 = $47 and the worker have only $2 which adds up to $49. Where do you think $1 lost in the process ?

you are supposed to add $3 to $47 because the worker's $2 is counted in the $47

u r talking about cost price in the first half and then reverse calculating it by sell price in the second half.so its obvious why they are not adding up

do like this they each have paid $23.5 so in total $47.now waht u r duin rong is that they actually bought the book for $45(after gettin money back) but they paid $47 because the cashier cheated $2 on them i.e $47 - $2
