Detailed Solution
Download Solution PDFदिया गया है:
A एक कार्य को पूरा कर सकता है = 4 दिनों में
B एक कार्य को पूरा कर सकता है = 9 दिनों में
प्रयुक्त सूत्र:
कुल कार्य = दक्षता × समय
गणना:
| दक्षता | व्यक्ति | समय | कुल कार्य |
| 9 | A | 4 | 36 |
| 4 | B | 9 |
अब,
(B + A) = 4 + 9 = 13 इकाइयाँ = 2 दिन
⇒ (13 × 2) = 26 इकाइयाँ = (2 × 2) = 4 दिन
⇒ 30 इकाइयाँ = 5 दिन
⇒ 36 इकाइयाँ = 5 + (6/9) = 5\(2\over3\) दिन
∴ सही उत्तर 5\(2\over3\) दिन है।
