Detailed Solution
Download Solution PDFदिलेले आहे:
X आणि Y एक काम अनुक्रमे 9 आणि 36 दिवसांत पूर्ण करू शकतात.
वापरलेले सूत्र:
काम = कार्यक्षमता × वेळ
गणना:
एकूण काम = (9, 36) चा लसावि
एकूण काम = 36 एकक
X ची कार्यक्षमता = 36/9 = 4 एकक/दिवस
Y ची कार्यक्षमता = 36/36 = 1 एकक/दिवस
X आणि Y एकआड दिवस काम करतात, X कामास सुरुवात करत असेल, तर
दोघांनी 2 दिवसांत 5 एकक काम केले आहे.
= (5 × 7) एकक → (2 × 7) दिवस
14 दिवसांत दोघांनी केलेले काम = 35 एकक
उर्वरित काम 1 एकक आहे, जे X हा 1/4 दिवसांत पूर्ण करेल.
एकूण लागलेला वेळ = 14 + 1/4
संपूर्ण काम 14(1/4) दिवसांत पूर्ण होईल.
