Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले आहे:
(राजू + रजत) यांना एकत्रितपणे काम पूर्ण करण्यासाठी लागणारा वेळ = 5 दिवस
एकट्या राजूला काम पूर्ण करण्यासाठी लागणारा वेळ = 7 दिवस
वापरलेले सूत्र:
एकूण काम = कार्यक्षमता × वेळ
गणना:
| कार्यक्षमता | व्यक्ती | वेळ | एकूण काम |
| 7 | राजू + रजत | 5 | 35 |
| 5 | राजू | 7 |
आता,
रजतची कार्यक्षमता = (7 - 5) = 2 एकक/दिवस
रजतला काम पूर्ण करण्यासाठी लागणारा वेळ = 35/2 = 17.5 दिवस
∴ 17.5 दिवस हे योग्य उत्तर आहे.
