Answer 1

To find the number of eggs, calculate the cost price of each egg and the selling price of each egg. Then divide the total cost price by the cost price of each egg.

Step-by-step explanation:

To find the number of eggs, we need to first determine the cost price of each egg. The woman spent Rs. 115.20 to buy some eggs, and 4 of them were broken. Therefore, the cost price of each egg is (115.20 / (total number of eggs - 4)).

Next, we need to find the selling price of each egg. The woman sold the remaining eggs at a profit of Rs. 0.40 and gained Rs. 16.80 after selling all the eggs. Hence, the selling price of each egg is (cost price + profit = cost price + 0.40).

Finally, we can calculate the number of eggs by dividing the total cost price (115.20) by the cost price of each egg.
