B. 62.5 प्रतिशत62.5 percent
Simple Explanation
Required percentage \(\frac{250}{400}\times100=62.5\%\) है। इसलिए दूसरा विकल्प सही है। यह percentage difference नहीं बल्कि one value as a percentage of another है। यदि पूछा जाता कि 400 value 250 से कितने percent अधिक है, calculation अलग होती। परीक्षा में wording को carefully distinguish करें। / The required percentage is \(\frac{250}{400}\times100=62.5\%\). Therefore, the second option is correct. This asks for one value as a percentage of another, not for percentage difference. If the question asked how much greater 400 is than 250, the calculation would be different. Read percentage wording carefully in examinations.
