If the total laptops sold by E is 20% more than that of by A, then find the difference between the total laptops sold by E and B.

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 9.

Step 1: Extract details from the provided pie chart.
From the given pie chart, we can observe the following data points:
• Title of the pie chart: Total laptops sold = 150
• Percentage of laptops sold by B = 30%
• Percentage of laptops sold by C = 12%
• Percentage of laptops sold by D = 38%

First, let us find the percentage share of laptops sold by A:
Percentage for A = 100% - (Percentage for B + Percentage for C + Percentage for D)
Percentage for A = 100% - (30% + 12% + 38%) = 100% - 80% = 20%

Step 2: Calculate the total laptops sold by A and B.

$\text{Laptops sold by A}=20\%\text{of}150=\frac{20}{100}\times 150=30$

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

Step 3: Calculate the total laptops sold by E.
It is given that the total laptops sold by E is 20% more than that sold by A.

$\text{Laptops sold by E}=30+(20\%\text{of}30)=30+6=36$

Step 4: Find the difference between total laptops sold by E and B.

$\text{Difference}=\text{Laptops sold by B}-\text{Laptops sold by E}$

$\text{Difference}=45-36=9$

Thus, the difference between the total laptops sold by E and B is 9.
