Question

If 2017 were to show the same growth as 2016 over 2015, the revenue in 2017 must be

• A. 194 lakh
• B. 187 lakh
• C. 172 lakh
• D. 177 lakh

Hint:

Add the three category bars to get the annual total. When a question says "same growth," add the \emph{absolute} increase (not percent) to the next year.

Answer 1

The Correct Option is D

Let the total revenue in 2015 be \(T_{2015}\) and in 2016 be \(T_{2016}\). The growth is \[ \Delta = T_{2016}-T_{2015}. \] If 2017 repeats the same growth, then \[ T_{2017}=T_{2016}+\Delta. \] Reading the totals from the chart and applying the same increment gives \[ T_{2017}=\boxed{177\ \text{lakh}}. \]
