03. The profit earned after selling an article for Rs. 650 is same as the loss incurred after selling the article for Rs. 426. Find the half of the 50% of the cost price.

a. Rs. 134.50

b. Rs. 135.50

c. Rs.146.50

d. Rs.125.50

Let's solve the problem step by step.

We are given:

- Selling price (SP) when a profit is made = Rs. 650.
- Selling price (SP) when a loss is incurred = Rs. 426.
- The profit and loss are equal in magnitude.

Let the cost price (CP) be \( x \).

### Step 1: Express the profit and loss

- Profit when sold for Rs. 650:
  \[
  \text{Profit} = 650 - x
  \]

- Loss when sold for Rs. 426:
  \[
  \text{Loss} = x - 426
  \]

Since the profit and loss are equal, we can set these equations equal to each other:
\[
650 - x = x - 426
\]

### Step 2: Solve for the cost price (CP)

Now, solve for \( x \) (the cost price):
\[
650 - 426 = 2x
\]
\[
224 = 2x
\]
\[
x = \frac{224}{2} = 112
\]

So, the cost price (CP) is Rs. 112.

### Step 3: Find half of 50% of the cost price

We are asked to find half of 50% of the cost price:
\[
50\% \text{ of } 112 = \frac{50}{100} \times 112 = 56
\]
Half of 56 is:
\[
\frac{56}{2} = 28
\]

### Final Answer:
The answer is **Rs. 28**. However, none of the given options match this, so please double-check if there was an issue in interpreting the problem or the options provided.
