Data regarding the sales of the number of shoes of sizes 7,1 and 9 in five showrooms, A to E, is given in the following stacked bar chart. Study the chart and answer the question.

By approximately what percentage is the sales of shoes of size 1 more than the sales of shoes of size 9 in showroom c?

Correct option is B

Given:

Sales of shoes of size 9 in showroom C = 740.

Sales of shoes of size 1 in showroom C = 2480.

Concept Used:

Percentage Increase = $$\left( \frac{\text{Difference}}{\text{Original Value}} \right) \times 100$$​​

Solution:

Percentage Increase = $$\left( \frac{\text{Sales of size 1} - \text{Sales of size 9}}{\text{Sales of size 9}} \right) \times 100$$​​

Difference = 2480 – 740 = 1740

Percentage Increase = $$\left( \frac{1740}{740} \right) \times 100$$​ = 235.14 %
