10% of 250.

**The reasoning** To find 10% of 250, remember that "percent" means "per hundred" or "out of 100." So 10% = 10/100 = 0.1 Now multiply: 10% of 250 = 0.1 × 250 = **25** Alternative method: 10% is the same as dividing by 10 (since 10% = 1/10). So 250 ÷ 10 = **25** **Why the wrong options tempt you** - **Option A (10):** You might confuse the percentage value itself (10) with the answer. Don't just copy the percentage number! - **Option C (50):** This is 20% of 250. Easy to get if you accidentally doubled somewhere. - **Option D (100):** This is 40% of 250. Way too large—happens if you mixed up your calculation steps. **Quick takeaway** For 10%, just divide by 10—it's your quickest friend! 10% of *any* number is that number ÷ 10. Master this shortcut and you'll breeze through percentage questions in seconds.
