গণিতের সমস্যা: ৭ কোন সংখ্যার ৫%? 🤔
আমরা জানি, শতকরা (%) একটি অনুপাত যা ১০০ এর ভগ্নাংশ হিসেবে প্রকাশ করা হয়। এই সমস্যাটিতে, আমাদের এমন একটি সংখ্যা খুঁজে বের করতে হবে যার ৫% হলো ৭।
সমাধানের ধাপ 🪜
- ধাপ ১: মনে করি সংখ্যাটি 'x'।
- ধাপ ২: প্রশ্নানুসারে, x এর ৫% = ৭
- ধাপ ৩: গাণিতিকভাবে লিখলে, (৫/১০০) * x = ৭
- ধাপ ৪: সরলীকরণ করে, x = (৭ * ১০০) / ৫
- ধাপ ৫: x = ১৪০
ফলাফল 🥳
সুতরাং, নির্ণেয় সংখ্যাটি হলো ১৪০। অর্থাৎ, ১৪০ এর ৫% হলো ৭।
অন্যান্য উদাহরণ 📚
| শতকরা (%) | সংখ্যা | ফলাফল |
|---|---|---|
| ১০% | ৫০ | ৫ |
| ২৫% | ১০০ | ২৫ |
| ৫০% | ২০০ | ১০০ |
আশা করি, এই ব্যাখ্যাটি বুঝতে সাহায্য করেছে। 👍
