#### Question

The following table shows the number of Buses and Trucks in nearest lakh units. Draw percentage bar-diagram. (Approximate the percentages to the nearest integer)

Year | No. of Trucks | No. of Buses |

2005-2006 | 47 | 9 |

2007-2008 | 56 | 13 |

2008-2009 | 60 | 16 |

2009-2010 | 63 | 18 |

#### Solution

The following table shows the number of Buses and Trucks in nearest lakh units.

Year | No of trucks | Percentage of trucks | No of buses | Percentage of buses |

2005-2006 | 47 | = `47/ ( 47 + 9 )` x 100 = `4700 / 56` = 83. 92 ≈ 84 | 9 | = `9 / ( 47 + 9 )` x 100 = ` 900 / 56 ` = 16.07 ≈ 16 |

2007-2008 | 56 | = ` 56/ ( 56 + 13)` x 100 = ` 5600 / 69` = 81.15 ≈ 81 | 13 | = `13 / ( 56 + 13)` x 100 = `1300/69` = 18.84 ≈ 19 |

2008-2009 | 60 | = ` 60 / ( 60 + 16 )` x100 = `6000 / 76` = 78.94 ≈ 79 | 16 | = ` 16 / ( 60+ 16 )` x 100 = `1600 / 76` = 21.05 ≈ 21 |

2009-2010 | 63 | = `63 / ( 63 + 18 )` x 100 = `6300/ 81`= 77.77 ≈ 78 | 18 | = ` 18 / ( 63 + 18 )` x 100 = `1800 / 81 ` = 22.22 ≈ 22 |

The percentage bar-diagram of the above table is as follows:
