উত্তরঃ

প্রশ্নে বলা হচ্ছে, মামুন Sweta কে কতগুলি কুকিজ দিয়েছিল?
মামুন Sweta কে কেবল 128টি কুকিজ দিলেই চতুর্থ বণ্টনে প্রত্যেকে 3টি করে কুকিজ পায়। দেখুন 1284 = 32টি এরপর 128-32-9 ৪-32=96 [শুধু Sweta এর 32টি বাদ যাবে] আবার, 96 + 4 = 24টি এরপর 96 - 48 = 4৪টি [Sweta এবং Swarna এর 24টি করে মোট 4৪টি বাদ যাবে] আবার, 48 : 4 = 12টি এরপর 48- 36 = 12টি [Sweta, Swarna এবং Sneha এর 12টি করে মোট 36টি বাদ যাবে] ... শেষের ধাপে প্রত্যেকেই 12+4 = 3টি করে পায়। তাই সঠিক উত্তর হবে 128টি।
