Question

Three teachers handed out mathand science textbooks for theirclasses. Two teachers had21 students each, and the lastteacher had 22. How manytextbooks were handed outaltogether?

Answer 1

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,

`21*2=42`

Therefore the total number of text books handed out is,

`42+22=64`

Thus, 64 textbooks were handed out altogether.
