A shopkeeper buys 100 eggs at Rs. 1.20 per piece. Unfortunately 4 eggs got spoiled during transportation. The shopkeeper sells the remaining eggs at Rs. 15 a dozen. Find his profit.

Answer

To solve the problem step by step, let's break it down clearly:

### Step 1: Calculate the Cost Price (CP) of 100 Eggs
The shopkeeper buys 100 eggs at Rs. 1.20 per egg.

\[ \text{Cost Price (CP)} = \text{Number of Eggs} \times \text{Cost per Egg} = 100 \times 1.20 = 120 \text{ Rs.} \]

**Hint:** To find the total cost, multiply the number of items by the cost per item.

### Step 2: Determine the Number of Spoiled Eggs
During transportation, 4 eggs got spoiled.

\[ \text{Remaining Eggs} = \text{Total Eggs} - \text{Spoiled Eggs} = 100 - 4 = 96 \text{ eggs} \]

**Hint:** To find the remaining items, subtract the spoiled or lost items from the total.

### Step 3: Calculate the Selling Price (SP) of the Remaining Eggs
The shopkeeper sells the remaining eggs at Rs. 15 per dozen. First, we need to find the selling price per egg.

\[ \text{Selling Price per Dozen} = 15 \text{ Rs.} \]
\[ \text{Selling Price per Egg} = \frac{\text{Selling Price per Dozen}}{12} = \frac{15}{12} = 1.25 \text{ Rs.} \]

Now, calculate the total selling price for 96 eggs.

\[ \text{Total Selling Price (SP)} = \text{Selling Price per Egg} \times \text{Remaining Eggs} = 1.25 \times 96 = 120 \text{ Rs.} \]

**Hint:** To find the total selling price, multiply the selling price per item by the number of items sold.

### Step 4: Calculate Profit or Loss
Now, we can find the profit or loss by subtracting the cost price from the selling price.

\[ \text{Profit or Loss} = \text{Selling Price} - \text{Cost Price} = 120 - 120 = 0 \text{ Rs.} \]

**Hint:** Profit or loss is determined by subtracting the cost from the selling price. If the result is positive, it's profit; if negative, it's a loss.

### Conclusion
The shopkeeper neither made a profit nor incurred a loss.

**Final Answer:** The profit is Rs. 0.
