A कार्य पूरा कर सकता है = 14 दिन
(A + B) कार्य पूरा कर सकता है = 7/2 दिन
प्रयुक्त सूत्र:
कुल कार्य = दक्षता × समय
गणना:
| दक्षता | व्यक्ति | समय | कुल कार्य |
| 1 | A | 14 | 14 |
| 4 | (A +B) | (7/2) |
अब,
B की दक्षता = (4 - 1) = 3 इकाई/दिन
कार्य को अकेले पूरा करने में लगा समय = 14/3 दिन
∴ सही उत्तर 14/3 दिन है।
