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 ?

TopNewestyou are supposed to add $3 to $47 because the worker's $2 is counted in the $47 – Tan Li Xuan · 4 years, 2 months ago

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 – Superman Son · 4 years, 2 months ago

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 - $2Log in to reply
