1. Rs 225 and \(33 \frac{1}{3}\%\)
2. Rs. 180 and \(33 \frac{1}{3}\%\)
3. Rs. 225 and 50%
4. Rs. 180 and 50%

Answer 1

Correct Answer - Option 4 : Rs. 180 and 50%

Given :

Selling price of two articles is Rs. 270

Formula used :

Profit = selling price - cost price 

 Calculations :

Selling price of 2 articles = 2 × 270 = 540 rupees 

Profit = selling price of two articles - Cost price of 2 articles 

Cost price = 540 - 2 × cost price         (profit = cost price of one article)

3 cost price = 540

Cost price = 540/3 = 180 rupees 

Profit % = (540 - 360)/(360) × 100 

⇒ 50% 

∴ The required answer is Rs. 180 and 50%
