Explanation:
- The marked price of the article is Rs 740.
- There are two successive discounts:
- The first discount is 15%.
- The second discount is x%.
- After both discounts, the selling price is Rs 566.10.
- To find the value of x:
1. Calculate the price after the first discount of 15%:
- \(740 \times (1 - 0.15) = 740 \times 0.85 = 629\).
2. Determine the effect of the second discount:
- Price after second discount is Rs 566.10.
- \(629 \times (1 - \frac{x}{100}) = 566.10\).
- Solve for x:
- \((1 - \frac{x}{100}) = \frac{566.10}{629}\).
- \((1 - \frac{x}{100}) = 0.9\).
- \(\frac{x}{100} = 0.1\).
- \(x = 10\).
- Options:
- Option 1: 12
- Option 2: 5
- Option 3: 10
- Option 4: 20
- The correct answer is Option 3: 10.
