Concept used:

In the tally, | → 1, || → 2, ||| →  3, |||| → 4 and |||| → 5

Calculation:

The number of students in marks interval of 0 to 5 = 0

The number of students in marks interval of 5 to 10 = 5 i.e(7, 9, 8, 9, 9)

The number of students in marks interval of 10 to 15 = 7 i.e(12, 11, 11, 13, 14, 14, 11)

The number of students in marks interval of 15 to 20 = 9 i.e(16, 17, 19, 18, 17, 16, 17, 18, 16)

The number of students in marks interval of 20 to 25 = 9 i.e(22, 24, 21, 22, 23, 23, 24, 24, 23)

From this observation, The correct tally table is

Interval of marks Tally marks of students
0-5 0
5-10 |||| 
10-15 |||| ||
15-20 |||| ||||
20-25 |||| ||||

∴ A correct answer is an option (A)
