Method of solving this Question on Data Interpretation for CAT

Note that we have done a very detailed analysis of how to go about solving stacked bar charts (similar to pie charts in many ways) in the solution to question 1 in this set. So, kindly go through that to get more insights. Let 2002 revenues be Z, and let 2001 revenues be Y. We know \\frac{Z}{Y}\\)=1.39.

Growth rate of SCT is \\frac{22.8}{21.1}\\)% * \\frac{Z}{Y}\\)-1 expressed as a percentage.

Or, \\frac{22.8}{21.1}\\) x 1.39 - 1 = 1.5 - 1 = 0.5.

There was a 50% growth rate.

The question is "what was the growth rate seen by SCT?"

Hence, the answer is "50%".

Choice A is the correct answer.
