এখানে, ৩ এবং ৪ এর ল.সা.গু. = ১২
এই ১২ দিনে ‘ক' কাজটি করে = ১২ বার
১২ দিনে 'খ' কাজটি করে = ৪ বার
১২ দিনে 'গ' কাজটি করে = ৩ বার
∴ মোট কাজ হয় অংশ
∴ কাজের বাকি থাকে অংশ
এখন, ১৩তম এবং ১৪তম দিনে ‘ক' একা করে অংশ
∴ কাজের বাকি থাকে অংশ
আবার, ১৫তম দিনে (ক + খ) করে অংশ
∴ কাজের বাকি থাকে অংশ
এখন, ১৬তম দিনে (ক + গ) করে অংশ
যেহেতু, কাজ বাকি ছিলো অংশ কিন্তু ১৬তম দিনে কাজ করা হয়েছে অংশ,
তাই ১৬তম দিনে কাজ হবে বেলা
অতএব, কাজ শেষে মোট সময় লাগবে দিন (উত্তর)
