Question

The distribution of students into 7 different classes is shown in the below bar graph.Which classes have the most and least number of students respectively?

• A. $7^{\text{th}}$ and $8^{\text{th}}$
• B. ${12}^{\text{th}}$ and ${11}^{\text{th}}$
• C. ${11}^{\text{th}}$ and $7^{\text{th}}$
• D. $7^{\text{th}}$ and ${11}^{\text{th}}$

Answer 1

The correct option is C ${11}^{\text{th}}$ and $7^{\text{th}}$

As we can see from the graph, the bar corresponding to class ${11}^{th}$ is the longest, and hence it has the maximum number of students.

The bar corresponding to class $7^{th}$ is the shortest, and so it has the minimum number of students.
