#### The histogram showing the weekly wages (in rupees) of workers in a factory is given alongside.

Answer the following about the frequency distribution:

(i) What is the frequency of the class 400-425?

(ii) What is the class having minimum frequency?

(iii) What is the cumulative frequency of the class 425 – 450?

(iv) Construct a frequency and cumulative frequency table for the given distribution.

**Solution:**

(i) The frequency of the class 400-425 is 18.

(ii) The class having minimum frequency is 475-500.

(iii) The cumulative frequency of the class 425-450 is (6 + 18 + 10) = 34.

(iv) The frequency table for the given distribution is:

Classes | Frequency | Cumulative Frequency |

375-400 | 6 | 6 |

400-425 | 18 | 24 |

425-450 | 10 | 34 |

450-475 | 20 | 54 |

475-500 | 4 | 58 |
