*Directions to Solve*

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

Production of Fertilizers by a Company (in 1000 tonnes) Over the Years

Required percentage = | (45 - 60) | % = -25%. | ||

60 |

There is a decline of 25% in production from 1997 to 1998.

Average production (in 10000 tonnes) of 1996 and 1997 | 40 + 60 | = 50. |

2 |

We shall find the average production (in 10000 tonnes) for each of the given alternative pairs:

2000 and 2001 = | 50 + 75 | = 62.5. |

2 |

1999 and 2000 = | 65 + 50 | = 57.5. |

2 |

1998 and 2000 = | 45 + 50 | = 47.5. |

2 |

1995 and 1999 = | 25 + 65 | = 45. |

2 |

1995 and 2001 = | 25 + 75 | = 50. |

2 |

The average production of 1996 and 1997 is equal to the average production of 1995 and 2001.

Required percentage = | (80 - 25) | x 100 | % = 220%. | ||

25 |

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

In 1996 = | (40 - 25) | x 100 | % = 60%. | ||

25 |

In 1997 = | (60 - 40) | x 100 | % = 50%. | ||

40 |

In 1998 there is a decrease in production.

In 1999 = | (65 - 45) | x 100 | % = 44.44%. | ||

45 |

In 2000 there is a decrease in production.

In 2001 = | (75 - 50) | x 100 | % = 50%. | ||

50 |

In 2002 = | (80 - 75) | x 100 | % = 6.67%. | ||

75 |

Clearlyl, there is maximum percentage increase in production in 1996.

Average production (in 10000 tonnes) over the given years

= | 1 | (25 + 40 + 60 + 45 + 65 + 50 + 75 + 80) = 55. |

8 |

The productions during the years 1997, 1999, 2001 and 2002 are more than the average production.
