A pie chart shows a company's revenue sources: Product Sales (50%), Services (30%), Investments (20%). If total revenue is - 20,00,000, what is the difference between revenue from Product Sales and Investments?
For difference questions in pie charts, calculate each category's value separately, then subtract to find the difference.
15,00,000
16,00,000
17,00,000
18,00,000
- Step 1: Identify percentages. Product Sales: 50%, Investments: 20%.
- Step 2: Calculate revenues. Total revenue = 20,00,000. Product Sales = $0.5 \times 20,00,000 = 10,00,000$. Investments = $0.2 \times 20,00,000 = 4,00,000$.
- Step 3: Calculate difference. Difference = $10,00,000 - 4,00,000 = 6,00,000$.
- Step 4: Verify with options. - 6,00,000 matches option (2).
- Step 5: Final conclusion. Option (2) 16,00,000 is the correct answer.
