Given that a machine is capable of filling 840 bottles in 6 hours. So, we can say that it is directly proportional to the time.

we can assume that bottles it will fill in five hours would be 'x'

So we got the relation; \frac{840}{6}=\frac{x}{5} , 

solving for x we will get  840\times 5 = 6\times x      or   x= \frac{840\times 5}{6}= 700.

Machine will fill 700 bottles in 5 hours.
