# 4.A machine in a soft drink factory fills 840 bottles in six hours. How many bottles will it fill in five hours?

We have 840 bottles filled in six hours. So, let x bottles be filled in five hours.

Since, the two quantities are directly proportional.So we have,

$$\frac{840}x=\frac{6}5$$

$$\Rightarrow 6 \times x=5\times 840$$

Therefore, we have $$x=\frac{5\times 840}{6}$$

$$x=5\times 140=700$$

Hence the required number of bottles filled in five hours=700
