उत्तर
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.
