Detailed Solution

Given table is,

Marks Obtained	10-20	20-30	30-40	40-50	50-60	60-70	70-80
No. of Students	2	5	4	2	5	6	9

Consider the table,

Marks Obtained	No. of Students	Cumulative Frequency
10-20	2	Less than 20	2
20-30	5	Less than 30	7
30-40	4	Less than 40	11
40-50	2	Less than 50	13
50-60	5	Less than 60	18
60-70	6	Less than 70	24
70-80	9	Less than 80	33

To represent less than type ogive, we have to plot the points

20, 2, 30, 7, 40, 11, 50, 13, 60, 18, 70, 24, 80, 33

on the graph paper and join them by free hand to get a smooth curve, which is the required less than type ogive.
