The price list of vegetables in a super market is given as follows :
| Item | Quantity | Price (₹) |
|---|---|---|
| Tomato | 1 kg | 40 |
| Potato | 2 kg | 25 |
| Carrot | 250 g | 20 |
| Bottlegourd | 1 kg | 10 |
| Chillies | 100 g | 10 |
| Lemon | 4 pieces | 10 |
Sanjay buys \(\frac{1}{2}\) kg tomatoes, 1 kg potatoes, \(\frac{1}{2}\) kg carrot, 250 g chillies and 6 lemons. He gives a note of ₹ 200 to the bill clerk at the counter. How much money will he get back ?
Answer: B
He gets back ₹ 87.50.
Work out each item from the unit prices:
- \(\frac{1}{2}\) kg tomatoes: 40 ÷ 2 = 20
- 1 kg potatoes (2 kg cost 25): 12.50
- \(\frac{1}{2}\) kg carrot (250 g cost 20): 40
- 250 g chillies (100 g cost 10): 25
- 6 lemons (4 cost 10): 15
\[ \begin{aligned} \text{Bill} &= 20 + 12.50 + 40 + 25 + 15 = 112.50 \\ \text{Change} &= 200 - 112.50 = 87.50 \end{aligned} \]
The option ₹ 112.50 is the bill itself, not the change; the others come from slips in one item.
