প্রদত্ত:

12 জন পুরুষ এবং 12 জন মহিলা 9 দিনে একটি কাজ সম্পূর্ণ করতে পারে।

6 জন পুরুষ এবং 15 জন মহিলা একই কাজ 12 দিনে সম্পূর্ণ করতে পারে।

গণনা:

ধরি, একজন পুরুষের কার্যক্ষমতা M একক এবং একজন মহিলার কার্যক্ষমতা W একক।

প্রশ্ন অনুসারে

মোট কাজ = (12M + 12W) x 9 ---(1)

মোট কাজ = (6M + 15W) x 12 ---(2)

⇒ (12M + 12W) x 9 = (6M + 15W) x 12

⇒ 108M + 108W = 72M + 180W

⇒ 36M = 72W

⇒ M : W = 2 : 1

মোট কাজ = (6M + 15W) x 12

⇒ (6 x 2 + 15 x 1) x 12

⇒ (12 + 15) x 12

⇒ 324

9 জন মহিলা কাজের অর্ধেক কাজ সম্পূর্ণ করতে = 324/2 x 1/9

⇒ 18 দিন

∴ 9 জন মহিলা কাজের অর্ধেক কাজ 18 দিনে সম্পূর্ণ করবে।
