Question

Sulekha bought 36 kg of sugar for Rs. 1,040. She sold it at a profit equal to the selling price of 10 kg of it. What is the selling price (in Rs.) for 5 kg of sugar ?
1. 200
2. 215
3. 220
4. 235

Answer 1

Correct Answer - Option 1 : 200

Given:

Cost price of 36 kg sugar = Rs.1040

Formula used:

Profit = Selling price - Cost price

Calculation:

CP of 1 kg sugar = Rs.1040/36 

According to the question 

SP × 10 = SP × 36 - CP × 36

⇒ CP × 36 = 26 × SP

⇒ 1040/ 36 × 36 = 26 × SP 

⇒ 1040/ 26 × 5 = 5 × SP

⇒ 200 = 5 × SP

∴ The selling price of 5 kg sugar = Rs.200
