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 ratio of TV sold by D to cell phones sold by B.

The correct option is 19:22.

From the given line graph, we can observe the following data points for the respective shops:

• Total TV sold by shop D (represented by the blue line) = 760
• Total TV sold by shop B (represented by the blue line) = 600
• Difference between cell phone and TV sold by shop B (represented by the orange line) = 280

It is given that the total number of cell phones sold by all shops is greater than the total number of TVs sold. Therefore, for any shop:

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

Using this relation for shop B:

$\text{Cell phones sold by shop B}=600+280=880$

Now, we calculate the required ratio of TV sold by shop D to cell phones sold by shop B:

$\text{Required Ratio}=\frac{\text{TV sold by D}}{\text{Cell phones sold by B}}=\frac{760}{880}$

Simplifying the ratio by dividing both numbers by 40:

$\text{Required Ratio}=\frac{19}{22}=19:22$

Hence, the required ratio is 19:22.
