Question

The bar chart below shows the sales (in Rs crores) of the top pain killer brands in India during 2005 and 2006.

Percentage of increase in sales from 2005 to 2006 is the highest for which brand of a pain killer?

Answer 1

Method: bracket the answer using the two extreme readable values instead of picking one midpoint value.

Reading the 2005 bar for Voveran conservatively as low as 16 crore gives: $(23-16)/16 \times 100 = 43.75\%$.
Reading the 2005 bar generously as high as 17 crore gives: $(23-17)/17 \times 100 \approx 35.3\%$.
The true percentage increase therefore lies somewhere between about 35% and 44%, depending on exactly how the bar height is read.
The midpoint of this range sits close to 39-40%, which lines up with the 40% option, the value nearest the center of the plausible range rather than an extreme edge case.

Using this bracketing approach, 40% remains the best-supported approximate answer, confirming option 2.

\[\boxed{40\%}\]
