MarksNo. of StudentsCumulative FrequencyPoints to be plotted01033(10,3)1020710(20,10)20301222(30,22)30401537(40,37)40502057(50,57)5060966(60,66)6070874(70,74)70801690(80,90)809014104(90,104)901006110(100,110)

To find the number of students scoring above 74% , we need to identify the number of students who have scored 74% and below

Joining the Point 74 on the X - axis with the ogive by drawing a perpendicular from it gives the Y- coordinate as 80.

80 students scored 74% and below.

The number of students who scored above 74% = Total number of students - Students scoring 74% and below.

= 110 - 80 = 30 Students
