Shopping questions are about two steps: add up what you buy, then take that away from the note you pay with. The trap options are the total itself, or the change for just one thing.
✓ You passed this topic’s test.
How to solve it
Total, then take away — “change = money given − total cost”
Add up the cost of everything you buy (or multiply for many of the same thing).
Change = the note you pay with − the total cost.
Check: change + total cost should give back the note.
Use it for: Money questions in Class 2–4 papers, and real shopping.
Worked example: A pencil box costs ₹38 and a pen costs ₹25. You pay for both with a ₹100 note. How much change do you get? ₹37
Total cost: ₹38 + ₹25 = ₹63.
Change: ₹100 − ₹63 = ₹37.
Check: ₹37 + ₹63 = ₹100 ✓
