Solution: প্রশ্নে বলা হচ্ছে যে, P একই সময়ে Q এর চেয়ে দ্বিগুণ কাজ করতে পারে । Q একা একটি কাজ 12 দিনে করলে P এবং Q একত্রে কাজটি কত দিনে করতে পারবে ? P এবং Q এর কাজের হারের অনুপাত = 2:1 কাজটি শেষ করতে P এবং Q এর সময় লাগে = 1:2 অনুপাতে । এখন, Q এর 1 দিনের কাজ = 1/12 অংশ অতএব, P এর 1 দিনের কাজ = 1/6 অংশ (P+Q) এর 1 দিনের কাজ = অংশ অর্থাৎ (P+Q) একত্রে 1/4 অংশ কাজ করে = 1 দিনে (P+Q) একত্রে 1 বা সম্পূর্ণ অংশ করে = দিনেRelated questions
