পার্টিতে উপস্থিত শিশু সংখ্যা
একটি পার্টিতে ৯৮ জন লোক আছে। সেখানে মহিলাদের সংখ্যা শিশুদের সংখ্যার দ্বিগুণ এবং শিশুদের সংখ্যা পুরুষদের সংখ্যার দ্বিগুণ।
সমস্যার বিশ্লেষণ
- মোট লোকসংখ্যা: ৯৮ জন 🧑🤝🧑
- মহিলা = ২ * শিশু 👩👩👧👦
- শিশু = ২ * পুরুষ 👶
গণিতের হিসাব
ধরি, পুরুষের সংখ্যা 'x' জন।
- অতএব, শিশুর সংখ্যা = ২x জন।
- মহিলার সংখ্যা = ২ * (২x) = ৪x জন।
- মোট লোকসংখ্যা = পুরুষ + শিশু + মহিলা
- সুতরাং, x + ২x + ৪x = ৯৮
- or, 7x = 98
- or, x = 14
ফলাফল
যেহেতু x=14,
| বিবরণ | সংখ্যা |
|---|---|
| পুরুষ 👨 | ১৪ |
| শিশু 👶 | ২৮ |
| মহিলা 👩 | ৫৬ |
| মোট 🧑🤝🧑 | ৯৮ |
অতএব, পার্টিতে ২৮ জন শিশু উপস্থিত ছিল। 🎉🎈
ধন্যবাদ! 🙏
