Question

$20\%$ apples in a basket go bad. If there are $40$ good apples in the basket. Find the total number of apples in the basket.

Answer 1

Here it is given that $20\%$apples go bad,

So, the remaining good apples =$100\%-20\%=80\%$

So, $80\%$ apples are good so, it must be equal to $40$.

Now let the total number of apples is $x$

So, $80\%$ of $x$ is equal to $40$ i.e.,

$\begin{array}{rcl}\frac{80}{100}\times x& =& 40\\ & \Rightarrow & x=\frac{40\times 100}{80}\\ & \Rightarrow & x=50\end{array}$

Hence, the total number of apples are $50$.
