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:
₹5,000
Let cost price be x.
Marked Price = x + 50% of x = 1.5x
Selling Price = 1.5x - 30% of 1.5x = 1.5x × (1 - 0.3) = 1.5x × 0.7 = 1.05x
1.05x = 5250 → x = 5250 ÷ 1.05 = ₹5,000
