Correct Answer - Option 1 : Rs. 2000

**Given: **

Loss on selling the leman set for Rs. 1280 = Profit earned by selling same for Rs. 1920

**Formula:**

Profit % = (Profit/CP) × 100

**Calculation:**

Let cost price be x

⇒1920 – x = x − 1280

⇒ 2x = 3200

⇒ x = 1600

Now, for profit of 25%

⇒ 1600 × (25/100) = 400

⇒ Selling price = (1600 + 400)

⇒ 2000

**∴**** The price at which the leman set was sold is Rs. 2000.**
