Correct answer: D. 66.67
Explanation
Let the original price be 100. Rohan's cost price = 100 − 25% = 75. To gain 25% on the original price the selling price must be 125. Required rise over cost = (125 − 75)/75 × 100 = 50/75 × 100 = 66.67 %.मान लीजिए मूल कीमत 100 है। रोहन का क्रय मूल्य = 100 − 25% = 75। मूल कीमत पर 25% लाभ हेतु विक्रय मूल्य 125 होना चाहिए। क्रय मूल्य से अभीष्ट वृद्धि = (125 − 75)/75 × 100 = 50/75 × 100 = 66.67 %।More Mathematical Reasoning and Aptitude questions
