detailed solution

Correct option is A

Converting the given distribution to a more than type distribution, we get

Production Yield (kg/ha)Number of farms
More than or equal to 50100
More than or equal to 55100-2 = 98
More than or equal to 6098-8= 90
More than or equal to 6590-12=78
More than or equal to 7078-24=54
More than or equal to 7554-38 =16

From the table obtained draw the ogive by plotting the corresponding points where the upper limits in x-axis and the frequencies obtained in the y-axis are (50, 100), (55, 98), (60, 90), (65, 78), (70, 54) and (75, 16) on

this graph paper. The graph obtained is known as more than type ogive curve.
