Abir, a trader, sells an item to a retailer at 20% discount, but charges 10% on the discounted price, for delivery and packaging. The retailer sells it for Tk. 2046 more, thereby earning a profit of 25%. At what price had the trader marked the item?

Let the marked price of the item be Tk. 100x
Discount % = 20%
Changes for delivery and packaging
= 10% on discounted price

Then
20% discount of 100x = 80x
Charges 10% on the discount price 80x = 88x
⇒ 88x + 88x × (25/100) - 88x = 2046
⇒ 110x - 88x = 2046
⇒ 22x = 2046
⇒ x = 93
Hence, 100x = 93 × 100
= 9300
Marked price = Tk. 9300
