Question

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

Answer 1

Number of bottles filled in $6$ hours $=840$

Therefore, number of bottles filled in $1$ hour $=\frac{840}{6}$

$=140$

So, the number of bottles filled in $5$ hours $=140\times 5$

$=700$

Hence, $\mathbf{700}$bottles will be filled in five hours.
