Construct a histogram to represent the above frequency distribution.

The given frequency distribution is in exclusive form, we will represent the class intervals along the X-axis and the corresponding frequency on the Y axis.


Now take the scale of,


1 big division = 40 rupees on X-axis,


1 big division = 2 workers on Y axis


We will draw the rectangles with the class intervals as basis and the corresponding frequency as the height.


Thus, we get the following histogram.
