3.5 – Application of Subtraction (Profit & Loss)
Do these (Page 96) – Write the Cost Price and Selling Price from the following contexts.
a) Seetha bought lemons for ₹600 and sold them for ₹850. → CP = ₹600, SP = ₹850
b) Lakshmi bought flowers for ₹1500 and sold them for ₹1350. → CP = ₹1500, SP = ₹1350
c) Veerayya sold bananas for ₹2450, previously bought for ₹1940. → CP = ₹1940, SP = ₹2450
d) Adilakshmi bought leafy vegetables for ₹150 and sold them for ₹120. → CP = ₹150, SP = ₹120
Complete the table:
| Context | CP | SP | More | Less |

Do these (Page 98)
1. Say whether profit or loss made in each of the following cases.
a) CP = ₹3100, SP = ₹2950 → Since SP < CP, it is a Loss of ₹150
b) CP = ₹2505, SP = ₹3160 → Since SP > CP, it is a Profit of ₹655
2. Padmaja bought a saree for ₹7500 and sold it to Rupa for ₹5850. Say whether Padmaja made profit or loss.
Given: CP = ₹7500; SP = ₹5850.
Task: Compare CP and SP to determine profit/loss.
Answer: Since SP < CP, Padmaja made a Loss of ₹1650 (7500 − 5850 = 1650).
1. Write 'P' for Profit and 'L' for Loss in the given brackets.
| CP | SP | P/L |
|---|---|---|
| ₹420 | ₹390 | L |
| ₹920 | ₹990 | P |
| ₹4860 | ₹5002 | P |
| ₹3140 | ₹2849 | L |
| ₹2195 | ₹3000 | P |
2. A shopkeeper bought a bag of sugar for ₹1650 and sold it for ₹90 more. Find whether he made profit or loss.
SP = 1650 + 90 = 1740. Since SP > CP, he made a Profit of ₹90.
3. Kumar bought oranges for ₹1520 and sold them for ₹150 less. Find whether he made profit or loss.
SP = 1520 − 150 = 1370. Since SP < CP, he made a Loss of ₹150.
4. Rahim bought umbrellas for ₹2100 and sold them for ₹1950. Find whether he made profit or loss.
Since SP (1950) < CP (2100), he made a Loss of ₹150 (2100 − 1950 = 150).
5. Salman bought a goat for ₹7850 and sold it for ₹8325. Find whether he made profit or loss.
Since SP (8325) > CP (7850), he made a Profit of ₹475 (8325 − 7850 = 475).

1. There were some books in a school. After distributing 297 books, 1,390 books remained. Ravi says that the library originally had 1,687 books. Do you agree with Ravi? Explain your answer using the relationship between addition and subtraction.
Given: Books distributed = 297; Books remaining = 1390.
Task: Check original total using Original = Distributed + Remaining.
Answer: 1390 + 297 = 1687. Yes, we agree with Ravi – the library originally had 1687 books, which also matches the subtraction fact 1687 − 297 = 1390.
2. A vendor purchased 4260 mangoes from a garden. While transporting them from the garden to the shop, 52 mangoes were damaged. Afterwards, the vendor sold 2548 mangoes. Determine the number of mangoes that the vendor still has.
Given: Mangoes purchased = 4260; Damaged = 52; Sold = 2548.
Task: Subtract damaged mangoes first, then subtract sold mangoes.
Answer: 4260 − 52 = 4208 (after damage); 4208 − 2548 = 1660 mangoes are still with the vendor.
3. A customer's electricity bill shows the following meter readings. How many units of electricity were used between the previous and present readings?
| Reading | Units (kW/h) |
|---|---|
| Previous Reading | 29381 |
| Present Reading | 30122 |
Answer: 30122 − 29381 = 741 units of electricity were used.
4. Meena had 40 more stickers than Sreeja. Later, Sreeja gave 15 stickers to Meena. Now, by how many stickers did Meena's collection exceed Sreeja's?
Given: Meena originally had 40 more stickers than Sreeja; Sreeja then gave Meena 15 more stickers.
Task: Find the new difference – when Sreeja gives 15 stickers to Meena, Meena's total goes up by 15 AND Sreeja's total goes down by 15, so the gap increases by 15+15=30.
Answer: New difference = 40 + 30 = 70 stickers. Meena's collection now exceeds Sreeja's by 70 stickers.
5. Identify the correct mathematical statement:
a) 4000−1500 > 6000−3000 → 2500 > 3000 → False
b) 8500−2000 = 9500−3000 → 6500 = 6500 → True ✓
c) 7200−1200 < 5000−500 → 6000 < 4500 → False
d) 3000−500 = 2000+500 → 2500 = 2500 → True ✓
Answer: b) 8500−2000 = 9500−3000 is the correct statement (note: option d is also mathematically true – 2500=2500 – so both b and d hold true).
6. Eswar bought watermelons for ₹2550. He sold them for ₹3100.
a) What is the cost price of watermelons? → ₹2550
b) What is the selling price of watermelons? → ₹3100
c) Has Eswar made a profit or loss? Find the answer.
Answer: Since SP (₹3100) > CP (₹2550), Eswar made a Profit of ₹550 (3100 − 2550 = 550).
