A mam brought 360 eggs at 18Rs. per dozen .40 eggs were broken and 20 eggs were rotten .What would be his profit or loss if he sells the left of the eggs at 20 Rs. per dozen ?

cost: 360 * 18/12

revenue: (360-40-20) * 20/12
subtract cost from revenue to get profit

I got hundred out of hundred in maths

Yes

To find out the profit or loss, we need to calculate the cost price and the selling price.

1. Cost price calculation:
The man bought 360 eggs at 18 Rs. per dozen. So, the cost of 360 eggs would be (360/12) * 18 = 60 * 18 = 1080 Rs.

2. Broken and rotten eggs:
Out of the 360 eggs, 40 were broken and 20 were rotten. So, the remaining eggs would be 360 - 40 - 20 = 300 eggs.

3. Selling price calculation:
The man sells the remaining eggs at 20 Rs. per dozen. Therefore, he sells 25 dozens (300/12 = 25) of eggs.

The selling price of 25 dozens of eggs would be 25 * 20 = 500 Rs.

Now, let's calculate the profit or loss:

Profit/Loss = Selling Price - Cost Price
= 500 - 1080
= -580 Rs.

Since the result is negative, it means the man has incurred a loss of 580 Rs.
