A, B, C এবং D এর বসার স্থান নির্ধারণ 🪑
এখানে A, B, C এবং D কে একটি সারিতে বসানো হবে। কিছু শর্তাবলী প্রযোজ্য:
- 🚫 C এবং D একসাথে বসতে পারবে না।
- 🚫 B তৃতীয় স্থানে বসতে পারবে না।
- যদি A তৃতীয় স্থানে না বসে, তবে C এর সম্ভাব্য স্থানগুলো নির্ণয় করতে হবে। 🤔
সম্ভাব্য স্থানসমূহ (যদি A তৃতীয় স্থানে না বসে):
যেহেতু C এবং D একসাথে বসতে পারবে না, তাই তাদের মধ্যে অন্তত একটি অক্ষর বসাতে হবে। এছাড়াও, B তৃতীয় স্থানে বসতে পারবে না। 🤓
| স্থান ১ | স্থান ২ | স্থান ৩ | স্থান ৪ |
|---|---|---|---|
| C ✅ | A/B | A/B/D | D/A/B |
| A/B/D | A/B/D | C ✅ | D/A/B |
ব্যাখ্যা:
- যদি A তৃতীয় স্থানে না বসে, তবে C প্রথম অথবা তৃতীয় স্থানে বসতে পারে। 👍
- যদি C প্রথম স্থানে বসে, তাহলে D দ্বিতীয়, তৃতীয় বা চতুর্থ স্থানে বসতে পারবে না।
- যদি C তৃতীয় স্থানে বসে, তাহলে D প্রথম, দ্বিতীয় বা চতুর্থ স্থানে বসতে পারবে না।
- B তৃতীয় স্থানে বসতে পারবে না, তাই অন্য স্থানগুলোতে বসতে পারবে।
অতএব, উত্তরটি হলো: C শুধুমাত্র প্রথম এবং তৃতীয় স্থানে বসতে পারে। 🎉
আরও কিছু সম্ভাব্য বিন্যাস:
- ABCD ❌ (C এবং D একসাথে)
- ACBD ✅
- ADBC ✅
- BACD ❌ (C এবং D একসাথে)
- BCAD ✅
- BDAC ✅
- CABD ✅
- CADB ✅
- CBAD ✅
- DABC ✅
লক্ষ্য করুন, এই বিন্যাসগুলো শুধুমাত্র উদাহরণ। আরও অনেক বিন্যাস সম্ভব। 📚
আশা করি, এটি আপনার কাজে লাগবে! 💡
