Question

3 friends went to a café and had chai. 1 cup cost 25 rupees. so they paid 75 rupees. The owner deduct 70 and return them 5 rupees. The friends gave 2 rupees to the waiter as a tip and divided the remaining 3 rupees between them. now if we calculate the chair cost 25-1=24 rupees to each. but when we sum up 24x3=72 and 72+2(tip)=74 now question is where is that 1 rupee?
I need a detail answer please!​

Answer 1

Step-by-step explanation:

This is just a way of putting forward the statement so as to cause confusion, whereas it is actually a very simple situation.

Total bill is Rs70. They pay 75. Rs70 goes for the bill payment. Rs 3 comes back to them. And Rs 2 goes to the waiter as the tip. 70+3+2=75

Now the confusion is being caused by mixing up things. If you say that the net payment of each person becomes Rs24 after getting 1 rupee back, then the total net payment should also be accounted as Rs72 only and not 75. Here is the catch. If each is paying Rs24, then total payment is only Rs72, out of which 70 goes towards bill payment and 2 as the tip. 70+2=72.

So the 1 rupee is lost only in the portraying of statement and no where else.

So don't get confused by questions. Keep your mind open and you'll see the simple solution always.
