Solution
Let the number of bottles filled by the machine in five hours be x.
The given information, in the form of a table, is as follows:
| Number of bottles | 840 | x |
| Time taken (in hours) | 6 | 5 |
The number of bottles and the time taken to fill these bottles are in direct proportion. Therefore, we obtain
= `840/6 = x/5`
x = `(840 xx 5)/6`
= 700
Thus, 700 bottles will be filled in 5 hours.
