# The marks obtained by 17 students in a mathematics test (out of 100) are given below:

91, 82, 100, 100, 96, 65, 82, 76, 79, 90, 46, 64, 72, 68, 66, 48, 49.

The range of the data is:

a. 46

b. 54

c. 90

d. 100

**Solution:**

Given

Marks obtained by 17 students (out of 100) is

91, 82, 100, 100, 96, 65, 82, 76, 79, 90, 46, 64, 72, 68, 66, 48, 49

We know that

Range = Maximum value - Minimum value

Here the maximum value is 100 and the minimum value is 46

Substituting the value

Range = 100 - 46

Range = 54

Therefore, the range of the data is 54.
