Given:

Marked price (MP) = ?

Discount = 20%

Charges for delivery and packaging = 10% on discounted price

Retailer's selling price (SP) = ₹ 4,092 more

Retailer's profit = 25%

Formula used:

Discounted price (DP) = MP × (1 - Discount%)

Selling Price by Trader (SPT) = DP × (1 + Charges%)

Cost Price for Retailer (CPR) = SPT

Retailer's Selling Price (RSP) = CPR × (1 + Profit%)

Difference in price = RSP - CPR

Calculation:

Let the marked price be MP = x

⇒ Discounted price DP = x × (1 - 0.20)

⇒ DP = 0.80x

⇒ SPT = 0.80x × (1 + 0.10)

⇒ SPT = 0.80x × 1.10

⇒ SPT = 0.88x

Retailer's Selling Price (RSP) = 0.88x × (1 + 0.25)

⇒ RSP = 0.88x × 1.25

⇒ RSP = 1.10x

Given that the retailer sells it for ₹ 4,092 more:

⇒ 1.10x - 0.88x = 4092

⇒ 0.22x = 4092

⇒ x = 4092 / 0.22

⇒ x = 18,600

∴ The correct answer is option 2.
