Question

Class mark of of $90-120$ is $100$.

• A. True
• B. False

Answer 1

The correct option is B False

Find the class mark of the class $90-120$.

Class-Mark $=\frac{Lowerlimit+Upperlimit}{2}$

The given class is $90-120$. So, the lower limit of this class is $90$ and the upper limit is $120$.

Class mark of class $90-120$ $=\frac{90+120}{2}$

$$\begin{gathered} =\frac{210}{2} \\ =105 \end{gathered}$$

Hence, the class mark of the class $90-120$ is $105$.

Therefore, the given statement is false.
