Three friends went to a restaurant. The bill was ₹25. Each put ₹10. When the waiter bought back ₹5, each took ₹1 back. The left over ₹2 was paid to the waiter.
The problem-
Each paid ₹10 but got back ₹1.
So, (₹9 ×3) =₹ 27 they paid.
They also paid ₹2 to the waiter. ₹27+₹2= ₹29.
What happened to the 30th rupee?

To Find : What happened to the 30th rupee
Solution:
Total Paid = Rs 30
Owner Returned Rs 5
Net Paid = 30 - 5 = Rs 25
Each Person get rs 1 back
Hence paid = Rs 9 each
Total Paid by 3 = 3 * 9 = 27 Rs
Actually net paid = Rs 25
27 - 25 = Rs 2 is the difference ( Tip given to waiter )
there is no meaning of adding 27 & 2 and compare with 30
its actually
27 - 2 = 30 - 5
=> 25 = 25
so nothing has gone anywhere
