Question

A bottle filling machine can fill 238 bottles in 2hrs. In 7hrs, it can fill

___ bottles.

Answer 1

$$\begin{array}{ccc}Numberofbottles& 238& y\\ Time\left(Inhours\right)& 2& 7\end{array}$$

The time taken and the number of bottles filled are directly proportional.

$\frac{A}{B}$= Constant

$\frac{A_1}{B_1}$ = $\frac{A_2}{B_2}$

$\frac{2}{238}=\frac{7}{y}$

$\Rightarrow y=\frac{7\times 238}{2}$

$\Rightarrow y=833$ bottles
