Question
Download Solution PDFA, B आणि C हे तीन धरणाचे दरवाजे 6 तासांत एक जलाशय भरू शकतात. 2 तास एकत्र काम केल्यानंतर, धरणाचा C दरवाजा बंद झाला. धरण दरवाजे A आणि B हे 7 तासात उर्वरित भाग भरू शकतात. जलाशय भरण्यासाठी धरणाच्या केवळ C दरवाजाने किती तास घेतले?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFA, B आणि C या धरण दरवाजांनी मिळून 1 तासात भरलेला जलाशय = 1/6
⇒ सर्व दरवाजांनी 2 तासात भरलेला जलाशय = 1/3
⇒ जलाशय भरणे बाकी आहे = 1 – 1/3 = 2/3
⇒ A आणि B द्वारे 1 तासात भरलेला जलाशय = 2/21
⇒ C दरवाजाद्वारे 1 तासात भरलेला जलाशय = 1/6 – 2/21 = 3/42
∴ केवळ धरण दरवाजा C ने 14 तासांत जलाशय भरला.Last updated on Jun 2, 2025
