A एक कार्य को पूरा कर सकता है = 60 दिन
प्रयुक्त सूत्र:
कुल कार्य = दक्षता × समय
गणना:
प्रश्नानुसार:
⇒ (A × 60) = (A × 15) + (B × 48)
⇒ (A × 45) = (B × 48)
⇒ A/B = 48/45 = 16/15
कुल कार्य = (A × 60) = 16 × 60 = 960 इकाइयाँ
A और B द्वारा एक साथ कार्य करने में लिया गया कुल समय = 960/(16 + 15)
⇒ 960/31
∴ सही उत्तर 960/31 है।
