Suji marked a dress 50% above the cost price. If she offers a discount of 30% on the marked price and the customer pays ₹5,250, the cost price is:

Marked Price (MP) = 1.5 × Cost Price (CP)

Discount = 30%

Selling Price (SP) = ₹5,250

Formula used:

SP = MP × (1 - Discount)

MP = 1.5 × CP

Calculation:

5,250 = 1.5 × CP × (1 - 0.30)

⇒ 5,250 = 1.05 × CP
