The Shopkeeper and the lady who made a purchase of Rs 200 with fake note | Puzzles for Interview - Interview Preparation PDF Download

Introduction

A lady came to a store and made a purchase of Rs. 200/-. The shopkeeper didn't take any profit from the sale. When the lady gave him a Rs. 1000/- note, the shopkeeper gave her Rs. 800/- back and kept Rs. 200/- for himself.

The Duplicate Note

Later, the shopkeeper at the next shop came with the same Rs. 1000/- note and said that it was a duplicate. 
The shopkeeper had to give him Rs. 1000/- in exchange for the fake note.

The Loss Calculation

To calculate the loss, we need to subtract what the shopkeeper gave to others from what he took. 
The shopkeeper took nothing from the lady as the Rs. 1000/- note was fake. 
He took Rs. 1000/- from the other shopkeeper. 
He gave the lady Rs. 200/- worth of goods and Rs. 800/- in change. 
He gave the other shopkeeper Rs. 1000/-.

The Total Loss


The total loss for the shopkeeper was (200 + 800 + 1000) - 1000 = Rs. 1000/-. 
This means that the shopkeeper lost Rs. 1000/- because of the lady's fake note.

Conclusion


The shopkeeper faced a loss of Rs. 1000/- because he gave the lady goods and change for a fake note. It's important to always check the currency being used to avoid such losses.
