  sorry ,answer is 50% .
  Cost price = 15 * 1 - 5 = 10
  Profit = 5
  % profit = 100*profit/cost = 50%

  Ahh! 😛
  Correct. The answer is 50%.
  
  Most of the people get this question wrong in the first attempt. Even I did. 😁
  
  But as I said think logically. Let me give the logical explanation:
  Only the banana vendor got it correct. Why? Because the profit is his daily bread. So he thought it logically, rather than applying the formula. He sold 1 banana for 1 rupee. He sold 15 bananas for 15 rupees. His profit is 5 rupees. So out of 15 rupees, his profit is 5 rupees; which means he bought the 15 bananas for 10 rupees and his profit is 5 rupees, i.e. half the price that he bought it for. So his profit is 50%. 😀

  I remember reading a book called Swami and Friends by R K Narayan , have you read it. It is based on life of Swami who is a school kid. He is given a similar problem in exam , and instead of solving it he gets angry because he feels the cost of the bananas is too high. 😀

  Yeah that's very correct, lemme put it in a simpler form.
  
  Formula=sellsprice - costprice
  
  profit =5rupee
  sellsprice =15
  and
  costprice =?
  
  5=15-costprice
  :. Costprice=10rupee
  
  %profit=profit/costprice*100%
  =5/10*100%
  =50%
  Therefore %profit=50%

  Yes, we can find it out with the formula.
  But the aim of this puzzle to answer it quickly, more logically.
  This is a kind of question that is often asked in entrance exams where we have to solve 1 question in less than 1 minute. If we start solving it with the formula, yeah 3minutes are gone there. 😁
