Solution

We take OX and OY as x-axis and y-axis respectively on the graph paper and O as the origin. We represent class interval on the x-axis by choosing the scale as 1cm=5 units. We represent the frequency on y-axis by taking the scale as 1cm=4.
We now draw graph for the given frequency table, so rectangles A,B,C,D and E are constructed.
