**Solution:**

Given, the data represents the cumulative frequency distribution of the marks secured by 50 students of a class.

We have to form the frequency distribution table for the data.

Marks |
Number of students (cf) |
Class interval |
Frequency |

Below 20 |
17 |
0 - 20 |
17 |

Below 40 |
22 |
20 - 40 |
22 - 17 = 5 |

Below 60 |
29 |
40 - 60 |
29 - 22 = 7 |

Below 80 |
37 |
60 - 80 |
37 - 29 = 8 |

Below 100 |
50 |
80 - 100 |
50 - 37 = 13 |
