X একাকী 1/3 অংশ করার পর বাকী কাজ = = অংশ যেহেতু Y করে অবশিষ্টাংশের অর্ধেক, তাই Y একাকী করে = অংশ; কাজ বাকী থাকে = অংশ, যেটুকু Y এবং Z সমানভাবে করে শেষ করে । অর্থাৎ 1/3 অংশ কাজের মধ্যে Y এবং Z প্রত্যেকে করে = অংশ; তাহলে X করে 1/3 অংশ; Y মোট করে অংশ এবং Z করে 1/6 অংশ । Y এর 1/2 অংশ কাজ যা X এবং Z এর একত্রিত কাজের সমান যা অপশন b) তে আছে ঃ Y did as much as X and Y did Individually.Related questions
