Azeem bought 30 dozen eggs. Out of which 30 eggs were rotten. If he bought it for Rs 1800. What should be the selling price of each egg to get a profit of one rupe per egg.

If the selling price was p, then to make a profit of 1 rupee per egg (of the original 30 dozen), we need

(30*12-30)p = 1800 + 1(30*12)
p = 6.55

To calculate the selling price of each egg, we first need to determine the cost price of each egg. Here's how we can do that:

Azeem bought 30 dozen eggs, which means he bought a total of 30 x 12 = 360 eggs.
Out of these 360 eggs, 30 were rotten. So, the number of usable eggs is 360 - 30 = 330.

Azeem bought these 330 eggs for Rs 1800.
Therefore, the cost price of each egg is Rs 1800 / 330 = Rs 5.45 (rounded to the nearest two decimal places).

Now, we want to make a profit of one rupee per egg.
So, the selling price of each egg should be the cost price per egg plus the desired profit per egg.

Selling price of each egg = Cost price of each egg + Desired profit per egg = Rs 5.45 + Rs 1.00 = Rs 6.45.

Therefore, the selling price of each egg should be Rs 6.45 in order to make a profit of one rupee per egg.
