#### Question

The marks scored by 750 students in an examination are given in the form of a frequency distribution table:

Marks | No. of students |

600 - 640 | 16 |

640 - 680 | 45 |

680 - 720 | 156 |

720 - 760 | 284 |

760 - 800 | 172 |

800 - 840 | 59 |

840 - 880 | 18 |

#### Solution

Suitable Points |

600-640 | 16 | 640 | 16 | (640,16) |

640-680 | 45 | 680 | 61 | (680,61) |

680-720 | 156 | 720 | 217 | ( 720, 217) |

720-760 | 284 | 470 | 501 | (760, 501) |

760-800 | 172 | 800 | 673 | ( 800, 673) |

800-840 | 59 | 840 | 732 | ( 840,732) |
