Question

Read the following bar graph and fill in the blanks:

The total strength of class ______and class_____ is equal to the strength of class $\mathrm{IX}$.

• A. $\mathrm{VI}$
• B. $\mathrm{VII}$

Answer 1

From the graph,

Strength of class $\mathrm{VI}$ students $+$ Strength of class $\mathrm{VII}$ students $=$Strength of class $\mathrm{IX}$ students

$$\begin{gathered} 45+60=105 \\ 105=105 \end{gathered}$$

Therefore, the sum of the strength of class $\mathrm{VI}$ students and the strength of class $\mathrm{VII}$ students is equal to the strength of class $\mathrm{IX}$ students.
