Question

The mid value of class range is 47.5 and the lower limit of the class range is 30. What will be the upper limit of this class range ?

• A. 60
• B. 62.5
• C. 65
• D. 67.5

Answer 1

The correct option is C

65

Let the upper limit be x

The mid value is given by : $\frac{UpperLimit+LowerLimit}{2}$

47.5 = $\frac{x+30}{2}$

$\Rightarrow$ x + 30 = 47.5 $\times$ 2 = 95

$\Rightarrow$ x = 95 - 30 = 65
