Detailed Solution
Download Solution PDFदिले:
A एक काम पूर्ण करू शकतो = 20 दिवस
B समान काम पूर्ण करू शकतो = 15 दिवस
वापरलेले सूत्र:
एकूण काम = कार्यक्षमता × वेळ
गणना:
| कार्यक्षमता | व्यक्ती | वेळ | एकूण काम |
| 3 | ए | 20 | ६० |
| 4 | बी | १५ |
प्रश्नानुसार:
⇒ B × 9 + A × D = 60
⇒ 4 × 9 + 3 × D = 60
⇒ 3D = (60 - 36) = 24
⇒ D = 24/3 = 8 दिवस
∴ योग्य उत्तर 8 दिवस आहे.
