**Common Information**

A soft drink company prepares drinks of three different flavours - $X$, $Y$ and $Z$. The production (in lakhs) of three flavours over a period of six years has been expressed in the bar graph provided below.

Q. |
For which of the following years the percentage of rise/fall in production from the previous year is the maximum for the flavour $Y$? |

✖ A. |
1996 |

✔ B. |
1997 |

✖ C. |
1998 |

✖ D. |
1998 |

**Solution:**

Option(**B**) is correct

The percentage rise/fall in production from the previous year for flavour $Y$ during various years are:

In 1996 $=\left[\dfrac{60 - 55}{55} × 100\right]\% = 9.09\%$ (increase)

In 1997 $=\left[\dfrac{60 - 50}{60} × 100\right]\% = 16.67\%$ (decrease)

In 1998 $=\left[\dfrac{55 - 50}{55} × 100\right]\% = 10\%$ (increase)

In 1999 $=\left[\dfrac{55 - 50}{55} × 100\right]\% = 9.09\%$ (decrease)

In 2000 $=\left[\dfrac{55 - 50}{50} × 100\right]\% = 10\%$ (increase)

Maximum change is decrease of 16.67% during **1997**
