Given Data:
The number of teachers is, 3.
Two teachers had 21 students each.
The last teacher had 22.
Since, two teachers had 21 students each, the number of textbooks handed out by these two teachers can be calculated as,
[tex]21\times2=42[/tex]Therefore the total number of text books handed out is,
[tex]42+22=64[/tex]Thus, 64 textbooks were handed out altogether.
