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 option is Rs 11,25,000.

From the pie chart titled "Total laptops sold = 150", we extract the following data:
• Total number of laptops sold = 150
• Percentage distribution of laptops sold by B = 30%
• Percentage distribution of laptops sold by C = 12%

Step 1: Calculate the revenue earned by B
First, find the number of laptops sold by B:

$\text{Number of laptops sold by B}=30\%\text{of}150$

$\text{Number of laptops sold by B}=\frac{30}{100}\times 150=45$

Since the selling price of each laptop sold by B is Rs 45,000, the total revenue of B is:

$\text{Revenue of B}=45\times 45000=\text{Rs 20,25,000}$

Step 2: Calculate the revenue earned by C
Next, find the number of laptops sold by C:

$\text{Number of laptops sold by C}=12\%\text{of}150$

$\text{Number of laptops sold by C}=\frac{12}{100}\times 150=18$

Since the selling price of each laptop sold by C is Rs 50,000, the total revenue of C is:

$\text{Revenue of C}=18\times 50000=\text{Rs 9,00,000}$

Step 3: Calculate the difference in revenue earned by B and C

$\text{Difference in revenue}=\text{Revenue of B}-\text{Revenue of C}$

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

Thus, the difference in revenue earned by B and C is Rs 11,25,000.
