Question

A shopkeeper sells an item for ₹430.5 after giving two successive discounts of 70% and 75% on its marked price. Had he not given any discount, he would have earned a profit of 40%. What is the cost price (in ₹) of the item?

The correct answer is
4,100

Calculating Marked Price from Selling Price and Discounts

We are given the final Selling Price (SP) and two successive discounts. We need to find the Marked Price (MP).

The formula for calculating Selling Price after successive discounts is:

\( SP = MP \times (1 - d_1) \times (1 - d_2) \)

Given values:

  • \(SP = ₹430.5\)
  • First discount (\(d_1\)) = 70% or 0.70
  • Second discount (\(d_2\)) = 75% or 0.75

Substitute the values into the formula:

\( 430.5 = MP \times (1 - 0.70) \times (1 - 0.75) \)

\( 430.5 = MP \times 0.30 \times 0.25 \)

\( 430.5 = MP \times 0.075 \)

Solve for Marked Price (MP):

\( MP = \frac{430.5}{0.075} \)

\( MP = 5740 \)

The Marked Price of the item is ₹5,740.

Calculating Cost Price Using Marked Price and Profit

If no discount were given, the Selling Price would be the Marked Price (₹5,740). This price would yield a profit of 40%.

The formula relating Selling Price (SP), Cost Price (CP), and Profit Percentage is:

\( SP = CP \times (1 + profit\%) \)

Here, the Selling Price (without discount) is the Marked Price:

  • \(SP = MP = ₹5740\)
  • Profit Percentage = 40% or 0.40

Substitute these values:

\( 5740 = CP \times (1 + 0.40) \)

\( 5740 = CP \times 1.40 \)

Solve for Cost Price (CP):

\( CP = \frac{5740}{1.40} \)

\( CP = 4100 \)

Final Answer

The Cost Price of the item is ₹4,100.
