Answer
Correct Answer: ₹ 250
Explanation
### Concept & Formula
To find the original Marked Price (MP) given the final Selling Price (SP) and multiple successive discounts, reverse the percentage reductions using multipliers.
$$ \text{MP} = \frac{\text{SP}}{\left(1 - \frac{d_1}{100}\right) \times \left(1 - \frac{d_2}{100}\right)} $$
### Step-by-Step Solution
* **Given:**
* Selling Price = ₹ $209$
* First discount = $12\%$
* Second discount = $5\%$
* **Calculation:**
* Let the original price be $x$.
* $x \times (1 - 0.12) \times (1 - 0.05) = 209$
* $x \times 0.88 \times 0.95 = 209$
* $0.88 \times 0.95 = 0.836$. So, $x \times 0.836 = 209$.
* $x = \frac{209}{0.836} = \frac{209000}{836} = 250$.
### Exam Strategy & Shortcut
Calculate the single equivalent discount: $12 + 5 - (12 \times 5)/100 = 17 - 0.6 = 16.4\%$.
This means the selling price is $(100 - 16.4)\% = 83.6\%$ of the original price.
$83.6\% = 209 \Rightarrow 1\% = \frac{209}{83.6} = 2.5$. Thus $100\% = 250$.
### Common Pitfall
Attempting to add the discounts ($12 + 5 = 17\%$) and saying the price is $83\%$ of the original, which gives an incorrect original price of roughly $251.8$.
### Final Answer
Therefore, the correct answer is **₹ 250**.
