Question

The bar chart below shows the sales (in Rs crores) of the top pain killer brands in India during 2005 and 2006.What is the approximate percentage of increase in the sales of Voveran from 2005 to 2006?

• A. 35%
• B. 40%
• C. 45%
• D. 50%

Hint:

Use the chart's approximate base and current values, then round to the nearest given option.

Answer 1

The Correct Option is B

Step 1: Read Voveran's sales from the chart.
From the chart, Voveran's sales were about Rs 16 to 17 crore in 2005 and about Rs 23 crore in 2006, since bar heights on a chart like this can only be read approximately.
Step 2: Apply the percentage-increase formula.
Percentage increase = [(2006 sales - 2005 sales) / 2005 sales] x 100.
Step 3: Substitute values.
Taking the 2005 figure as about 16.5 crore, the middle of the readable range, and the 2006 figure as 23 crore: increase = 23 - 16.5 = 6.5 crore. Percentage increase = (6.5 / 16.5) x 100 ~ 39.4%.
Step 4: Round to the nearest option.
Since the question asks only for an approximate percentage and the bar heights cannot be read to a fraction of a unit, 39.4% rounds to the nearest listed choice, which is 40%. The other options (35%, 45%, 50%) are farther from the calculated figure. So the answer is option 2, 40%.
