I bought 12 dozens of eggs at Rs 7.20 per dozen .Eighteen eggs were broken .I sold the remaining eggs at the rate of Rs 7.50 per dozen .find my gain or loss.answer is Rs 7.65

Answer 1

cost = 7.2(12) = 86.4
18 eggs = 1.5 dozen
so you sold 10.5 dozen at 7.5
return = 10.5(7.5) = 78.75

loss = 86.4 - 78.75 = 7.65
