dude..72 itself includes rs. 2 why are u adding it back again..

72+3 = 75.. lol

They paid Rs. 25 for the first time the bill was of Rs. 75. When the manager gave them the discount. They paid only Rs. 24 and bill amount is Rs. 72. From that the waiter had got the Rs. 2 and the answer is if they are calculating a wrong amount. If they calculate the amount what they paid than they will get the answer. And 72 itself includes Rs.2

72+3=75
