A person bought an article and sold it at a profit of 20%. Had he bought it at 20% less, what would have been the profit percentage if the selling price had been the same?
Elementary MathematicsProfit and Loss
- A25%
- B40%
- C50%
- D60%
Explanation
Take CP = Rs. 100: a 20% profit gives SP = Rs. 120. If the article had been bought 20% cheaper, CP = Rs. 80 while SP stays Rs. 120, so the profit is Rs. 40 on Rs. 80, i.e. 50%. The trap is to answer 40% (the profit in rupees relative to the original CP); the percentage must be computed on the actual (reduced) cost. The answer is (C).
