উপস্থিত সদস্যদের তালিকা 👪
- মোট সদস্য: ৭৭ জন
- মহিলা: শিশুদের দ্বিগুণ 👩👩👧👦
- শিশু: পুরুষের দ্বিগুণ 👶
- পুরুষ: সর্বনিম্ন সংখ্যা 👨
গণিতের হিসাব ➗➕
ধরি, পুরুষের সংখ্যা x
তাহলে, শিশুদের সংখ্যা 2x
এবং, মহিলাদের সংখ্যা 4x
সুতরাং, x + 2x + 4x = ৭৭
অথবা, 7x = ৭৭
অতএব, x = ১১
সুতরাং, পুরুষের সংখ্যা = ১১
অতএব, শিশুদের সংখ্যা = 2 * ১১ = ২২
অতএব, মহিলাদের সংখ্যা = 4 * ১১ = ৪৪
ফলাফল 🎉
অতএব, পার্টিতে ২২ জন শিশু উপস্থিত ছিল।
