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​

Answer 1

RANGE:--)

the range of a set of data is the difference between the largest and smallest values.

FORMULA TO FINDE RANGE:--)

$Range (x)= Max(x) \: - Min(x)$

So, here

The maximum marks is

$100$

And the minimum marks is

$46$

So, According to the formula we will do :-

$100 - 46$

Which is

$54$

ANS IS (B)
