Detailed Solution
Download Solution PDFदिया गया है:
A एक कार्य को कर सकता है = 5 दिनों में
B एक कार्य को कर सकता है = 10 दिनों में
प्रयुक्त सूत्र:
कुल कार्य = दक्षता × समय
गणना:
माना कि, एक साथ कार्य करने के दिनों की संख्या (A + B) = D है।
| दक्षता | व्यक्ति | समय | कुल कार्य |
| 2 | A | 5 | 10 |
| 1 | B | 10 |
प्रश्न के अनुसार:
⇒ (A + B) × D + B × 8 = 10
⇒ (2 + 1) × D + 1 × 8 = 10
⇒ 3 × D = (10 - 8)
⇒ D = 2/3 दिन
∴ सही उत्तर 2/3 दिन है।
