दिया गया है:

A एक कार्य को पूरा कर सकता है = 7 × 3 = 21 दिन

B एक कार्य पूरा कर सकता है = 10 × (7/2) = 35 दिन

प्रयुक्त सूत्र:

कुल कार्य = दक्षता × समय

गणना:

दक्षता  व्यक्ति समय कुल कार्य
5 21 105
3 35

अब,

A और B द्वारा कार्य पूरा करने में लिया गया समय = 105/8

⇒ 13 दिन

∴ सही उत्तर 13 दिन है।
