Verified Answer
The difference between the selling price at a discount of 40% and that...
Let the Marked Price be x
In the first case, Selling Price at 40% discount = 60x/100
Single discount equivalent to 20% and 10% successive discounts = [20 + 10 – {(20 × 10)/100}] = 28%
Selling Price in the second case = 72x/100
Now, 72x/100 - 60x/100 = 132
12x/100 = 132
x = 100 × 132/12 = Rs. 1100

Problem:
The difference between the selling price at a discount of 40% and that at two successive discounts of 20% and 10% is Rs. 132. Find the marked price of the laptop?

Solution:
Let's assume the marked price of the laptop as 'x'.

Step 1: Calculate the Selling Price at a Discount of 40%
When a discount of 40% is given, the selling price is calculated as:
Selling Price = Marked Price - (Discount * Marked Price)
Selling Price at a discount of 40% = x - (0.40 * x)
Selling Price at a discount of 40% = x - 0.40x
Selling Price at a discount of 40% = 0.60x

Step 2: Calculate the Selling Price at Successive Discounts of 20% and 10%
When two successive discounts of 20% and 10% are given, the selling price is calculated as:
Selling Price = Marked Price - (Discount1 * Marked Price) - (Discount2 * (Marked Price - (Discount1 * Marked Price)))
Selling Price at successive discounts of 20% and 10% = x - (0.20 * x) - (0.10 * (x - (0.20 * x)))
Selling Price at successive discounts of 20% and 10% = x - 0.20x - 0.10(x - 0.20x)
Selling Price at successive discounts of 20% and 10% = x - 0.20x - 0.10(x - 0.20x)
Selling Price at successive discounts of 20% and 10% = x - 0.20x - 0.10x + 0.02x
Selling Price at successive discounts of 20% and 10% = 0.72x

Step 3: Calculate the Difference in Selling Prices
Difference in Selling Prices = Selling Price at a discount of 40% - Selling Price at successive discounts of 20% and 10%
132 = 0.60x - 0.72x
132 = -0.12x

Step 4: Calculate the Marked Price
To find the marked price, we need to solve the equation:
-0.12x = 132
x = 132 / -0.12
x = -1100

Since the marked price cannot be negative, we discard this solution.

Therefore, the marked price of the laptop is Rs. 1100 (Option C).
