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
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
To find the gain or loss, we need to calculate the cost price (CP) and the selling price (SP).
1. Cost price (CP) of 12 dozens of eggs:
CP = Number of dozens * Cost per dozen
= 12 * Rs 7.20
= Rs 86.40
2. Number of eggs remaining after 18 were broken:
Since one dozen contains 12 eggs, we initially had:
Number of eggs = Number of dozens * 12
= 12 * 12
= 144 eggs
After deducting 18 broken eggs, we have:
Number of remaining eggs = 144 - 18
= 126 eggs
3. Selling price (SP) of the remaining eggs:
SP = Number of dozens * Selling price per dozen
= (126 / 12) * Rs 7.50
= 10.50 * Rs 7.50
= Rs 78.75
Now, to find the gain or loss:
Gain or Loss = Selling Price (SP) - Cost Price (CP)
= Rs 78.75 - Rs 86.40
= -Rs 7.65
Since the result is negative, it represents a loss of Rs 7.65.
