Use a graph sheet to draw an ogive for the distribution.
Estimate the number of shooters who obtained a score of more than 85%.
For finding the number of shooters who obtained a score more than 85%, take a point U at 85 on the x - axis.
From it, draw a vertical line, which touches the ogive at point V and from it, draw a horizontal line which touches the y - axis at point W. At that point W, we are getting those shooters who obtained a score till 85.
No. of shooters at point W = 118
number of shooters who obtained a score of more than 85% = Total number - No. of shooters who scored till 85
= 155 - 118
= 37
∴ number of shooters who obtained a score of more than 85% is 37.
