Question

Homi · Accepted Answer

We need to find the class where no students were absent.

Step 1 — Understanding the graph

Look at the bar graph. The bottom line shows the Class numbers from 1 to 8. The side line shows the Number of students. The height of each bar tells us how many students were absent. The scale says 1 unit length means 1 student.

Step 2 — Finding absent students for each class

Let us read the number of absent students for each class.

Number of absent students in Class 1: $= 3$

Number of absent students in Class 2: $= 5$

Number of absent students in Class 3: $= 4$

Number of absent students in Class 4: $= 2$

Number of absent students in Class 5: $= 0$

Number of absent students in Class 6: $= 1$

Number of absent students in Class 7: $= 5$

Number of absent students in Class 8: $= 7$

Step 3 — Identifying full attendance

Full attendance means that zero students were absent. We look for the class that has 0 absent students. From our list, Class 5 has 0 absent students. So, Class 5 had full attendance that day. The class with full attendance is:

$\boxed{\text{Class 5}}$
