The line graph given below shows the total number of TV sold and difference between cell phone and TV sold by five different shops (A, B, C, D and E).

Note – Total cell phones sold by all the shops are more than the total TV sold.
Items = cell phone + TV

Average number of cell phone sold by B, C and E.

The correct answer is 800.

Step-by-Step Explanation:

First, let's analyze the line graph to extract the total number of TVs sold (blue line) and the difference between cell phones and TVs sold (orange line) for the shops B, C, and E:

For Shop B:
- Total TV sold (blue line) = 590
- Difference between Cell phone and TV sold (orange line) = 280

For Shop C:
- Total TV sold (blue line) = 680
- Difference between Cell phone and TV sold (orange line) = 390

For Shop E:
- Total TV sold (blue line) = 90
- Difference between Cell phone and TV sold (orange line) = 370

Since the total number of cell phones sold by all the shops is greater than the total number of TVs sold, we can determine the number of cell phones sold by each shop using the formula:

$\text{Cell phones sold}=\text{TV sold}+\text{Difference}$

Now, let's calculate the number of cell phones sold by shops B, C, and E:

- Cell phones sold by B:
$590+280=870$

- Cell phones sold by C:
$680+390=1070$

- Cell phones sold by E:
$90+370=460$

To find the average number of cell phones sold by B, C, and E:

$\text{Average}=\frac{870+1070+460}{3}$

$\text{Average}=\frac{2400}{3}=800$
