Explanation:
To create a histogram based on the provided information, we'll need to plot the marks ranges on the x-axis and the number of students on the y-axis. Here's how you can present the data:
```
Marks Range | No. of Students
-------------------------------|-------------------------
10 - 20 | 20
20 - 40 | 20
40 - 70 | 120
70 - 100 | 80
```
Then, you would create a bar graph where the x-axis represents the marks ranges and the y-axis represents the number of students. Each bar's height would correspond to the number of students falling within that marks range.
