Explanation:
Here's a breakdown of this problem:
- Cost Price (CP): Let's assume the cost price is $100.
- Marked Price (MP): The shopkeeper marks it 40% above the CP. This means MP = $100 + 40% of $100 = $140.
- Discount: A 25% discount is given on the MP. This makes the Selling Price (SP) = $140 - 25% of $140 = $140 - $35 = $105.
- Gain/Loss Calculation: The gain is calculated as SP - CP = $105 - $100 = $5.
- Gain Percent: This is calculated as ($5 / $100) * 100 = 5%.
Correct Answer: 3. 5% Gain
