**Common Information**

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

Q. |
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**
