2000 | 193 | 96 | 288 | 112 | 248 | 144 | 260 | 92 | 200 | 104 |

Required difference

= (272 + 240 + 236 + 256 + 288) - (200 + 224 + 248 + 272 + 260)

= 88.

Total number of Peons working in the Company in 1999

= (820 + 184 + 152 + 196 + 224) - (96 + 88 + 80 + 120)

= 1192.

**Number of Managers working in the Company:**

In 1995 | = 760. |

= 1252. |

Percentage increase in the number of Managers

= | (1252 - 760) | x 100 | % = 64.74%. | ||

760 |

**Number of Technicians working in the Company:**

In 1995 | = 1200. |

In 2000 | = (1200 + 272 + 240 + 236 + 256 + 288) - (120 + 128 + 96 + 100 + 112) |

= 1936. |

Percentage increase in the number of Technicians

= | (1936 - 1200) | x 100 | % = 61.33%. | ||

1200 |

**Number of Operators working in the Company:**

= 1444. |

Percentage increase in the number of Operators

= | (1444 - 880) | x 100 | % = 64.09%. | ||

880 |

**Number of Accountants working in the Company:**

In 1995 | = 1160. |

In 2000 | = (1160 + 200 + 224 + 248 + 272 + 260) - (100 + 104 + 96 + 88 + 92) |

= 1884. |

Managers | = (760 + 280 + 179) - (120 + 92) = 1007. |

Technicians | = (1200 + 272 + 240) - (120 + 128) = 1464. |

Operators | = (880 + 256 + 240) - (104 + 120) = 1152. |

Accountants | = (1160 + 200 + 224) - (100 + 104) = 1380. |

Peons | = (820 + 184 + 152) - (96 + 88) = 972. |

Pooled average of all the five categories of employees working in the Company in 1997

= | 1 | x (1007 + 1464 + 1152 + 1380 + 972) |

5 |

= | 1 | x (5975) |

5 |

= 1195.
