4.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?

Given that 24 children are given 5 sweets each and also the number of the children were reduced by 4 so, their number becomes 24 – 4 = 20.
Let each child get x sweets when their number is 20.

As per given we see that less children will get more sweets. So, it is a case of inverse proportion.

∴\( 24 \times 5 = 20 \times x\)

\(\Rightarrow x= \frac { 24\times 5 }{ 20 } = 6\)

Hence, each child will get 6 sweets.
