Some of you may have heared some "Tricky" questions that do look simple but on the paper are very controversial to answer Example: Three Boys Went To The Shop And Purchased Some Items,The overall cost became 20$/Boy.At that instance the shopkeeper was not on the shop,so the cost was decided by the helper.When the shopkeeper came back ,he said to the helper "you overpriced the rate by 5 $,go return the money back ". The Helper was a bit greedy so he kept 2$ in his pocket,and returned 1$ to each of the boys. So After This, Situation Became As Thus: Charge on Each Boy=19$ Number of Boys =3 i.e,. Total Money On Side of The Three Boys=19X3=57$ Money in Pocket Of Helper=2$ 57+2=59 ,So Where Is The One Dollar ? Please Ask Such Question In This Thread ,If You Know Some !
