## Task 1 - 070521

The students of a class collected a total of $336 \mathrm{~kg}$ of waste paper. From $1 \mathrm{~kg}$ of waste paper, a paper mill produces exactly $700 \mathrm{~g}$ of pure white paper, and from every $30 \mathrm{~g}$ of this, a writing pad is made. (In production, white paper is not made directly from waste paper. However, by adding waste paper, a corresponding amount of raw material is saved.)

Give the maximum number of pads that can be made from the collected waste paper!
Calculation of the amount of pure white paper: Since

$$
336 \cdot 700=235200 \quad \text { and } \quad 235200 \text{ g}=235.2 \text{ kg}
$$

from $336 \text{ kg}$ of waste paper, at most $235.2 \text{ kg}$ of white paper can be produced.

Calculation of the number of exercise books:

Since $235200: 30=7840$, from $336 \text{ kg}$ of waste paper, at most 7840 exercise books can be produced.
