1. **Problem Statement:** A seller buys an electric appliance for 5000 and wants to earn a profit of 20%. He marks the selling price accordingly. If the customer pays outright, a discount of 5% is given. We need to find:
- The marked price of the article.
- The discount given in rupees.
- The profit earned by selling the article.
2. **Formulas and Rules:**
- Cost Price (CP) = 5000
- Profit % = 20%, so Profit = $\frac{20}{100} \times CP$
- Marked Price (MP) is the price before discount.
- Discount % = 5%, so Discount = $\frac{5}{100} \times MP$
- Selling Price (SP) = MP - Discount
- Profit = SP - CP
3. **Calculate Profit Amount:**
$$\text{Profit} = \frac{20}{100} \times 5000 = 1000$$
4. **Calculate Selling Price (SP):**
Since profit is 1000,
$$SP = CP + \text{Profit} = 5000 + 1000 = 6000$$
5. **Calculate Marked Price (MP):**
Given a 5% discount on MP results in SP,
$$SP = MP - \frac{5}{100} \times MP = MP \times (1 - 0.05) = 0.95 \times MP$$
So,
$$MP = \frac{SP}{0.95} = \frac{6000}{0.95} = 6315.79$$
6. **Calculate Discount in Rupees:**
$$\text{Discount} = MP - SP = 6315.79 - 6000 = 315.79$$
7. **Calculate Profit Earned:**
Profit is already calculated as 1000.
**Final answers:**
- Marked Price = 6315.79
- Discount = 315.79
- Profit Earned = 1000
Marked Price Profit
