Question

If a box of sweets is divided among $24$ children, they will get $5$ sweets each. How many would each get, if the number of the children is reduced by $4$?
Fill up the blank with the right answer ___ .

Answer 1

As the number of children increases, the number of sweets to each decreases.

So, $xy=$constant

$x_1=24$ and $y_1=5$

$x_2=20$ and $y_2=?$

$x_1{y}_1=x_2{y}_2$
$y_2=\frac{24\times 5}{20}=6$

So, each child gets $6$ sweets.
