Question

The monthly profits (in Rs.) of 100 shops are distributed as follows:

Profits per shop: 0 - 50 50 - 100 100 - 150 150 - 200 200 - 250 250 - 300
No. of shops: 12 18 27 20 17 6

Draw the frequency polygon for it.

Solution

Firstly, we make a cumulative frequency table.

Profit per shop No. of shop More than profit Cumulative frequency Suitable points
0-50 12 0 100 (0, 100)
50-100 18 50 88 (50, 88)
100-150 27 100 70 (100, 70)
150-200 20 150 43 (150, 43)
200-250 17 200 23 (200, 23)
250-300 6 250 6 (250, 6)

Now, plot the frequency polygon (or more than ogive) using suitable points.

  Is there an error in this question or solution?
