Challanges
The shopkeeper's challenge is to make profit by asking for a higher price, or lowering the price to get the customer to buy more - for eg if you buy 2 I'll give you a 5 npr discount, while the customer's challenge is to avoid getting cheated!
Questions to be asked
Did you receive the exact number of items you asked for?
Is the calculation correct for the items you bought and sold?
How much will it be if I buy 2 or 3 or 5 (ie practice multiplication) - will you give me a discount?
If a set of 3 costs 6 rupees, how much will 1 cost (practice division) ?
What will you do if the shopkeeper is charging more than the marked price?
