Option 4 : Rs. 50,000

Given:

Discount = 20%

Amount earned in whole transaction = Rs. 5000

Formula:

Selling price = Marked Price × (100 – Discount%)/100

Calculation:

Let the marked price of the laptop be x,

Cost price of laptop = 80% of x = 0.8x

⇒ Amount earned by him resting the laptop = 0.4x

Selling price of the laptop = 0.5x

Profit = Selling price of the laptop + amount earned by renting - cost price of the  table 

⇒ 5000 = 0.5x + 0.4x - 0.8x

⇒ 5000 = 0.9x - 0.8x

⇒ 0.1 x = 5000

⇒ x = Rs. 50,000

∴ The marked price of the laptop is Rs. 50,000.
