A, B आणि C हे काम अनुक्रमे 10, 20 आणि 40 दिवसांत स्वतंत्रपणे पूर्ण करू शकतात.
काम पूर्ण करण्यासाठी दर तिसर्या दिवशी B आणि C दोघे A ला मदत करतात. जाते.
वापरलेली संकल्पना:
एकूण काम = कार्यक्षमता (दररोज केलेले काम) × एकूण वेळ
गणना:
ल.सा.वि (10, 20, 40) = 40
एकूण काम 40 युनिट आहे असे समजा.
A ची कार्यक्षमता = 40/10 = 4 युनिट्स
B ची कार्यक्षमता = 40/20 = 2 युनिट्स
C ची कार्यक्षमता = 40/40 = 1 युनिट
3 दिवसांच्या समूहामध्ये,एकूण काम केले= 4 × 2 + (4 + 2 + 1) = 15 युनिट्स
अशा 3 दिवसांच्या दोन समूहामध्ये एकूण काम केले = 15 × 2 = 30 युनिट्स
पुढील 2 दिवस एकूण काम केले जाईल= 30 + 4 + 4 = 38 युनिट्स
आता काम पूर्ण होण्यासाठीलागणारा वेळ= 3 × 2 + 2 + \(\frac {40 - 38}{4 + 2 + 1}\) = \(8 \frac{2}{7}\) दिवस
∴ काम पूर्ण करण्यासाठी \(8 \frac{2}{7}\) दिवस लागतील.
