Question

3. I bought some eggs at the price of £0.2 per egg. I later sold half of them at the price of £3.36 per dozen. The remaining half were sold at £1.56 per half dozen. My total profit earned is £25.20. How many eggs did I buy?

Answer 1

$\fontsize{18}{10}{\textup{\textbf{The number of eggs is 30 dozens or 360}}}$

Step-by-step explanation:

Let the total no of eggs be 'x' dozens

According to given condition

SP of all eggs-CP of all eggs=25.2

3.36*x/2+2*1.56*x/2-x*0.2*12=25.2

6.48*x/2-2.4x=25.2

3.24x-2.4x=25.2

=>0.84x=25.2

=>x=30

you bought 30 dozens of eggs
