Question

350 boxes can be placed in 25 cartons. How many boxes can be placed in 16 cartons?

Answer 1

Let x be the required number of boxes.

No. of boxes	350	$x$
No. of cartons	25	16

Less number of boxes will require less number of cartons.
So, it is a case of direct proportion.
$$\begin{gathered} \mathrm{Now},\frac{350}{25}=\frac{x}{16} \\ \Rightarrow x=\frac{350\times 16}{25} \\ \Rightarrow x=224 \end{gathered}$$

∴ 224 boxes can be placed in 16 cartoons.
