A shopkeeper buys 8 articles for Rs. 115 and sells all these articles at Rs. 17.5 each. Find his profit or loss.

Answer

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

### Step 1: Identify the Cost Price (CP)
The cost price for 8 articles is given as Rs. 115.

### Step 2: Calculate the Selling Price (SP) of one article
The selling price of one article is given as Rs. 17.5.

### Step 3: Calculate the Selling Price (SP) of 8 articles
To find the total selling price for all 8 articles, multiply the selling price of one article by the number of articles:
\[ \text{Selling Price of 8 articles} = 8 \times 17.5 \]
Calculating this gives:
\[ 8 \times 17.5 = 140 \]
So, the selling price of 8 articles is Rs. 140.

### Step 4: Determine Profit or Loss
Now, we compare the selling price with the cost price:
- Cost Price (CP) = Rs. 115
- Selling Price (SP) = Rs. 140

Since the selling price is greater than the cost price, there is a profit.

### Step 5: Calculate the Profit
Profit can be calculated using the formula:
\[ \text{Profit} = \text{Selling Price} - \text{Cost Price} \]
Substituting the values we have:
\[ \text{Profit} = 140 - 115 = 25 \]
Thus, the profit is Rs. 25.

### Final Answer
The shopkeeper makes a profit of Rs. 25.
