The boxes are to be filled with apples in a heap. If 24 apples are put in a box then 27 boxes are needed. If 36 apples are filled in a box how many boxes will be needed?

Given:

If 24 apples are put in a box then 27 boxes are needed.
 To do:

We have to find the number of boxes needed when 36 apples are filled in a box.

Solution:

The boxes are to be filled with apples in a heap.

The total number of apples $=$ Total number of boxes $\times$ Number of apples in a single box

Therefore,

In the first instance when 24 apples are put in a box,

The total number of apples $=27 \times 24=648$

The total number of boxes required when 36 apples are filled in a box$=$Total number of apples $\div$ Number of apples in a single box

$= \frac{648}{36}$

$= 18$

Therefore, 18 boxes will be needed when 36 apples are filled in a box.
