The selling price of each laptop sold by B is Rs 45,000, while the selling price of each laptop sold by C is Rs 50,000. Calculate the difference in revenue earned by B and C.

Read the following pie chart carefully and answer the questions given below. The following pie chart shows the percentage distribution of laptops sold by four persons A, B, C and D.

The correct answer is Rs 11,25,000.

Step 1: Extract data from the pie chart image
From the given pie chart image, we can observe the following key data points:
- Total number of laptops sold by all four persons (A, B, C, D) = 150
- Percentage distribution of laptops sold:
• Person B = 30%
• Person C = 12%

Step 2: Calculate the number of laptops sold by B and C
Number of laptops sold by B:

$\text{Laptops sold by B}=30\%\×150=\frac{30}{100}\×150=45$

$\text{Laptops sold by C}=12\%\×150=\frac{12}{100}\×150=18$

Step 3: Calculate total revenue generated by B and C
The selling price of each laptop sold by B is Rs 45,000.

$\text{Revenue earned by B}=45\×\text{Rs 45,000}=\text{Rs 20,25,000}$

$\text{Revenue earned by C}=18\×\text{Rs 50,000}=\text{Rs 9,00,000}$

Step 4: Find the difference in revenue between B and C

$\text{Difference in Revenue}=\text{Rs 20,25,000}-\text{Rs 9,00,000}=\text{Rs 11,25,000}$
