Study the given bar graph and answer the question that follows.

The following bar graph shows the quarterly profit (in lakhs) of a departmental store from 1997 to 2000.

What was the percentage increase in annual profit of the departmental store from 1997 to 2000?

Correct option is C

Given:

The quarterly profits (in lakhs) for the years 1997 to 2000 are provided in the bar graph.

Annual profit in 1997: 135 + 115 + 90 + 70 = 410 lakhs

Annual profit in 2000: 150 + 180 + 210 + 230 = 770 lakhs

Concept Used:

Percentage Increase = $$\left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100$$​

Solution:

Percentage Increase = $$\left( \frac{770 - 410}{410} \right) \times 100$$​

= $$\left( \frac{360}{410} \right) \times 100$$ 

= $$\frac{3600}{41}$$%

= 87$$\frac{33}{41}$$%​
