Detailed Solution
Download Solution PDFदिलेले आहे:
A एक काम एवढ्या दिवसात पूर्ण करू शकतो = 4 दिवस
B एक काम एवढ्या दिवसात पूर्ण करू शकतो = 9 दिवस
वापरलेले सूत्र:
एकूण काम = कार्यक्षमता × वेळ
गणना:
| कार्यक्षमता | व्यक्ती | वेळ | एकूण काम |
| 9 | A | 4 | 36 |
| 4 | B | 9 |
आता,
(B + A) = 4 + 9 = 13 एकक = 2 दिवस
⇒ (13 × 2) = 26 एकक = (2 × 2) = 4 दिवस
⇒ 30 एकक = 5 दिवस
⇒ 36 एकक = 5 + (6/9) = 5\(2\over3\) दिवस
∴ योग्य उत्तर 5\(2\over3\) दिवस आहे.
