The cost price of 13 articles is equal to the selling price of 11 articles. Find the profit percent?
Correct answer: B. 18 2/11%
- A. 15 5/15%
- B. 18 2/11%
- C. 16 2/3%
- D. 30%Quiz Mode Feature
Explanation
Let the selling price of one article be Rs.s. Since the cost price of 13 articles equals the selling price of 11 articles, the cost per article is Rs.11s/13. The gain per article is Rs.s - Rs.11s/13 = Rs.2s/13, and gain percentage is (2/11) x 100 = 18 2/11%. Students often choose 16 2/3% by using the difference of 2 articles over 13 instead of measuring gain against cost price.
