Dear Student,
Please find below the solution to the asked query:
Difference between class marks = 5
And
5/2 = 2 .5
Respectively, the classes for these class marks are as follows:
2.5 - 7.5
7.5 - 12.5
12.5 - 17.5
17.5 - 22.5
22.5 - 27.5
Hence, the class corresponding to class mark 20 = 17.5 - 22.5 ( Ans )
Hope this information will clear your doubts about Statistics.
