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.

From the given line graph, we can observe the data for five different shops (A, B, C, D, and E):
- Blue line: Represents the total number of TVs sold.
- Orange line: Represents the difference between cell phones sold and TVs sold.
- Note: Total cell phones sold by any shop are greater than the total TVs sold, which implies:

$\text{Cell Phones Sold}=\text{TVs Sold}+\text{Difference}$

Let's analyze the visual data for shops B, C, and E:

1. For Shop B:
Total TVs sold (blue line) = 590
Difference between cell phones and TVs sold (orange line) = 290

$\text{Cell phones sold by B}=590+290=880$

2. For Shop C:
Total TVs sold (blue line) = 680
Difference between cell phones and TVs sold (orange line) = 390

$\text{Cell phones sold by C}=680+390=1070$

3. For Shop E:
Total TVs sold (blue line) = 90
Difference between cell phones and TVs sold (orange line) = 360

$\text{Cell phones sold by E}=90+360=450$

Now, calculate the total number of cell phones sold by B, C, and E combined:

$\text{Total Cell Phones}=880+1070+450=2400$

Finally, calculate the average number of cell phones sold by shops B, C, and E:

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