Question

Jack bought $4$ $dozen$ eggs at $₹60$ per dozen out of which $6$ eggs were broken. What percent of his money goes waste ?

Answer 1

Step 1: Cost of $4$$dozen$eggs

Cost of $1$$dozen$eggs $=₹60$

Cost of $4$$dozen$eggs $=₹60\times 4=₹240$

Step 2: Cost of $6$ eggs

Cost of $12$ eggs $=₹60$

Cost of $1$ egg $=₹\frac{60}{12}$

Cost of $6$ eggs $=₹\frac{60}{12}\times 6=₹30$

Step 3: Percentage of money which was waste

Percentage $=\frac{moneywaste}{originalprice}\times 100\%$

$$\begin{gathered} =\frac{30}{240}\times 100\% \\ =\frac{25}{2}\% \\ =12.5\% \end{gathered}$$

Therefore, $12.5\%$money wasted due to $6$ broken eggs.
