Options

A. Profit of Rs 75
B. Loss of Rs 75
C. Profit of Rs 30
D. Loss of Rs 30

Answer

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

### Step 1: Calculate the Selling Price of the First Electric Iron
- **Cost Price (CP)** of the first electric iron = Rs. 900
- **Gain** = 10%

To find the Selling Price (SP), we use the formula:
\[ \text{SP} = \text{CP} + \text{Profit} \]
Where Profit is calculated as:
\[ \text{Profit} = \frac{\text{Gain} \times \text{CP}}{100} \]

Calculating the Profit:
\[ \text{Profit} = \frac{10 \times 900}{100} = 90 \]

Now, substituting back to find SP:
\[ \text{SP} = 900 + 90 = 990 \]

### Step 2: Calculate the Selling Price of the Second Electric Iron
- **Cost Price (CP)** of the second electric iron = Rs. 1200
- **Loss** = 5%

To find the Selling Price (SP), we use the formula:
\[ \text{SP} = \text{CP} - \text{Loss} \]
Where Loss is calculated as:
\[ \text{Loss} = \frac{\text{Loss Percentage} \times \text{CP}}{100} \]

Calculating the Loss:
\[ \text{Loss} = \frac{5 \times 1200}{100} = 60 \]

Now, substituting back to find SP:
\[ \text{SP} = 1200 - 60 = 1140 \]

### Step 3: Calculate Total Cost Price and Total Selling Price
- **Total CP** = CP of first iron + CP of second iron
\[ \text{Total CP} = 900 + 1200 = 2100 \]

- **Total SP** = SP of first iron + SP of second iron
\[ \text{Total SP} = 990 + 1140 = 2130 \]

### Step 4: Calculate the Overall Profit or Loss
To find the overall profit or loss, we use the formula:
\[ \text{Profit} = \text{Total SP} - \text{Total CP} \]

Calculating the Profit:
\[ \text{Profit} = 2130 - 2100 = 30 \]

### Conclusion
Avinash made a total profit of Rs. 30 on the transaction involving both electric irons.
