Question Details

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

Total item sold by E is what percentage more/less than total TV sold by D.

Correct Answer :

Option A

31.57%

31.57%

Solution :

Correct Answer: 31.57%

Let us first extract the relevant data points from the line graph for shops D and E:
1. For Shop D:
Total TV sold (indicated by the blue line) = 760
2. For Shop E:
Total TV sold (indicated by the blue line) = 80
Difference between the number of Cellphones and TVs sold (indicated by the orange line) = 360

According to the given note:
Total cell phones sold by all the shops are more than the total TV sold. Thus, for Shop E, the number of cell phones sold is greater than the number of TVs sold:
Cellphone sold by E - TV sold by E = 360

Substitute the value of TV sold by E (80) into the equation:

\text{Cellphone sold by E} - 80 = 360

\text{Cellphone sold by E} = 360 + 80 = 440

Now, find the total items (Cellphone + TV) sold by Shop E:

\text{Total items sold by E} = 440 + 80 = 520

We need to calculate what percentage more/less the total items sold by E (520) is compared to the total TV sold by D (760).
Since 520 is less than 760, the percentage less is given by:

\text{Required Percentage} = \frac{760 - 520}{760} \times 100

\text{Required Percentage} = \frac{240}{760} \times 100 = \frac{6}{19} \times 100 \approx 31.57\%

Therefore, the total items sold by E is approximately 31.57% less than the total TV sold by D.
