Question

The Mid value of class range is 142. The Upper limit of the class is 164 , What will be the lower limit ?

• A. 140
• B. 130
• C. 125
• D. 120

Answer 1

The correct option is D

120

Let the lower limit of the class be x

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

$\Rightarrow$ 142 = $\frac{x+164}{2}$

$\Rightarrow$ 164 + x = 284

$\Rightarrow$ x = 284 - 164 = 120
