Correct Answer - Option 1 : Rs. 800
Given:
CP = Rs. 3000 of each,
Total profit = Rs. 1200
Formula used:
SP = CP + Profit
Calculation:
Let the selling price of articles be Rs. 4a and Rs. 5a respectively.
⇒ (4a – 3000) + (5a – 3000) = 1200
⇒ a = 800
Selling price of two articles = Rs. 3200 and Rs. 4000.
Profit earned by selling article for Rs. 3200 = 3200 – 3000 = Rs. 200
Profit earned by selling article for Rs. 4000 = 4000 – 3000 = Rs. 1000
∴ Required difference = 1000 – 200 = Rs. 800
