Common Information

Study the bar chart and answer the question based on it.

 Q. Common Information Question: 4/5 In which year was the percentage increase in production as compared to the previous year the maximum?
 ✖ A. 2002 ✖ B. 2001 ✖ C. 1997 ✔ D. 1996

Solution:
Option(D) is correct

The percentage increase in production compared to previous year for different years are:

\begin{align*} \text{In 1996,}\\ &=\left[\dfrac{40 - 25}{25} × 100\right]\%\\ &= 60\%.\\ \text{In 1997,}\\ &=\left[\dfrac{60 - 40}{40} × 100\right]\%\\ &= 50\%. \end{align*}

In 1998 there is a decrease in production.

\begin{align*} \text{In 1999,}\\ & =\left[\dfrac{65 - 45}{ 45} × 100\right]\%\\ & = 44.44\% \end{align*}

In 2000 there is a decrease in production.

\begin{align*} \text{In 2001,}\\ & =\left[\dfrac{75 - 50}{ 50} × 100\right]\%\\ & = 50\%.\\ \text{In 2002,}\\ & =\left[\dfrac{80 - 75}{ 75} × 100\right]\%\\ & = 6.67\%. \end{align*}

Clearly, there is maximum percentage increase in production in 1996
