Dear Student,


Given that :-
 
Marks Nos of Student  
Less than 10 2  
Less than 20 12  
Less than 30 37  
Less than 40 57  
Less than 50 60  
 
Marks Frequency Nos of Student (frequency)
0-10 2 2
10-20 =12-2=10 10
20-30 =37-12=25 25
30-40 =57-37=20 20
40-50 =60-57=3 3

Formula Used:-
Nos of Student in Class 10-20 = Nos of Student Obtain marks Less than 20 - Nos of Student obtain marks Less than 10.

Similarly For all Class of Marks.
