Question
A batch of bottles was 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?
Solution
Let the number of boxes filled, by using 20 bottles in each box, be x.
The following table is obtained:
| Number of bottles | 12 | 20 |
| Number of boxes | 25 | x |
The more the number of bottles, the less will be the number of boxes.
Therefore,
12 × 25 = 20 × x
`x = (12 xx 25)/20`
x = 15
Hence, the number of boxes required to pack these bottles is 15.
