➤ ৫ জন মহিলা ৫ দিনে কাজ শেষ করে ⇒ ১ জন মহিলা পুরো কাজ শেষ করবে = ৫ × ৫ = ২৫ দিনে ⇒ তাহলে ১ দিনে ১ জন মহিলার কাজ = ১/২৫ ⇒ ৩ জন মহিলার ১ দিনের কাজ = ৩/২৫ ➤ ৫ জন শিশু ৬ দিনে কাজ শেষ করে ⇒ ১ জন শিশু কাজ শেষ করবে = ৬ × ৫ = ৩০ দিনে ⇒ তাহলে ১ দিনে ১ জন শিশুর কাজ = ১/৩০ ⇒ ৩ জন শিশুর ১ দিনের কাজ = ৩/৩০ = ১/১০ ➤ এখন ৩ জন মহিলা ও ৩ জন শিশুর ১ দিনের মোট কাজ = = (৩/২৫) + (১/১০) = (6/50) + (5/50) = 11/50 ⇒ তারা একসাথে পুরো কাজ শেষ করবে = ৫০/১১ দিনRelated questions
