2. Rs. 4,50,000
3. Rs. 7,45,000
4. Rs. 6,56,000

Answer 1

Correct Answer - Option 3 : Rs. 7,45,000

Given

Cost price of 1 laptop = Rs. 50,000

Cost price of 1 desktop = Rs. 40,000

Profit on laptop = 5%

Profit on desktop = 10%

Formula used

Selling price = Cost price + Profit

Calculation

Cost price of 10 laptop = 10 × 50,000

⇒ Rs. 5,00,000

Cost price of 5 desktop = 5 × 40,000

⇒ Rs. 2,00,000

Profit on laptop = 5,00,000 × (5/100)

⇒ Rs. 25,000

Profit on desktop = 2,00,000 × (10/100)

⇒ Rs. 20,000

Selling price = (5,00,000 + 25,000) + (2,00,000 + 20,000)

⇒ Rs. 5,25,000 + Rs. 2,20,000

⇒ Rs. 7,45,000

∴ Total sale price is Rs. 7,45,000
