Q.1
Using the same expense distribution (Rent 30%, Food 25%, Transport 15%, Savings 20%, Other 10%, total ₹40,000), find the amount spent on Rent and Transport combined.
Show answer
Answer: ₹18,000
Solution:
- Combine the percentages first: Rent + Transport = 30% + 15% = 45%.
- 45% of ₹40,000 = (45/100) × 40,000 = ₹18,000.

Q.2
Using the same family expense chart (Rent 30%, Food 25%, Transport 15%, Savings 20%, Other 10%), find the ratio of the amount spent on Rent to the amount spent on Food.
Show answer
Answer: 6 : 5
Solution:
- Since both are percentages of the SAME total, their ratio is just the ratio of the percentages: 30 : 25.
- Simplify: 30 : 25 = 6 : 5.

Q.3
In a pie chart, four categories take up 80°, 100°, 70° and 60°. Find the degree and the percentage of the fifth (unstated) category.
Show answer
Answer: 50°, ≈ 13.9%
Solution:
- Sum of the known degrees = 80 + 100 + 70 + 60 = 310°.
- Remaining degree = 360° − 310° = 50°.
- Percentage = (50/360) × 100 ≈ 13.9%.

Q.4
In Year 1 (total budget ₹10,00,000), Marketing was 20% of the budget. In Year 2 (total budget ₹15,00,000), Marketing was 15% of the budget. Did the actual amount spent on Marketing increase or decrease?
Show answer
Answer: Increased (₹2,00,000 to ₹2,25,000), despite the percentage falling
Solution:
- Year 1 amount = 20% of 10,00,000 = ₹2,00,000.
- Year 2 amount = 15% of 15,00,000 = ₹2,25,000.
- Even though the percentage fell from 20% to 15%, the actual amount spent increased (₹2,00,000 → ₹2,25,000), because the total budget grew by more than the percentage shrank.

In a pie chart, the angle representing a company’s Marketing budget is 72°. If the total budget is ₹15,00,000, find the amount allocated to Marketing.

Solution:
- Convert the angle to a percentage: (72/360) × 100 = 20%.
