      A batch of bottles were packed in 25 boxes with 12 bottles in each box. If the same batch is packed using 20 bottles in each box, how many boxes would be filled?

Answer:

Let the boxes be x, when the same batch is packed using 20 bottles. We have the following tables

No. of boxes	x	25
No. of bottles	20	12

This is a case of inverse proportion.

\[x\times 20=25\times 12\]

\[\Rightarrow \]   \[x=\frac{25\times 12}{20}\]

= 15

Thus, 15 boxes would be filled, when the same batch is packed using 20 bottles.
