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

Find the difference between sum of cell phone sold by C and E together and total items sold by A.

The correct answer is 680.

From the given line graph, we can observe the values for the total number of TVs sold (represented by the blue line) and the difference between cell phones and TVs sold (represented by the orange line) for each shop:

Step 1: Formula Definition
Since total cell phones sold are greater than the total TVs sold for all shops:
$\text{Cell Phone sold}=\text{TV sold}+\text{Difference}$
$\text{Total items sold}=\text{Cell Phone sold}+\text{TV sold}$

Step 2: Calculate values for Shop A
Total TV sold by shop A = 325
Difference between cell phone and TV sold by shop A = 200
$\text{Cell Phone sold by A}=325+200=525$
$\text{Total items sold by A}=525+325=850$

Step 3: Calculate values for Shop C
Total TV sold by shop C = 680
Difference between cell phone and TV sold by shop C = 400
$\text{Cell Phone sold by C}=680+400=1080$

Step 4: Calculate values for Shop E
Total TV sold by shop E = 90
Difference between cell phone and TV sold by shop E = 360
$\text{Cell Phone sold by E}=90+360=450$

Step 5: Calculate the final required difference
Sum of cell phones sold by shop C and shop E together:
$\text{Sum}=1080+450=1530$

Difference between the sum of cell phones sold by C and E together and the total items sold by shop A:
$\text{Required Difference}=1530-850=680$

Hence, the final answer is 680.
