Best Answer Explained in Below-:

X একা 1/3 অংশ করার পর কাজ বাকি থাকে 1 - ⅓ = 2/ 3 অংশ। Y করে অবশিষ্টাংশের অর্ধেক = 2/3x1/2 = 1/3 অংশ বাকি থাকে ⅔ - ⅓ = 1/3 অংশ, যেটুকুY ও Z সমানভাবে করে শেষ করে। এখন 1/3 অংশ কাজের Y ও Z প্রত্যেকে করে 1/3x1/2 = ⅙ অংশ সুতরাং X করে 1/3 অংশ: Y মোট করে 1/3 + 1/6 বা 1/2 অংশ এবং Z করে 1/6 অংশ। অর্থাৎ Y এর ½ অংশ কাজ যা X এবং Z এর একত্রিত কাজের সমান কিন্তু তাদের এক জনের চেয়ে বেশি।
