Detailed Solution
Download Solution PDF⇒ पाईप P द्वारे 1 मिनिटात भरलेल्या टाकीचे प्रमाण = 1/32
⇒ पाईप Q द्वारे 1 मिनिटात भरलेल्या टाकीचे प्रमाण = 1/36
⇒ पाईप R द्वारे 1 मिनिटात रिकाम्या होणाऱ्या टाकीचे प्रमाण = 1/20
⇒ तीनही पाईप चालू केल्यावर 1 मिनिटात भरलेल्या टाकीचे प्रमाण = 1/32 + 1/36 - 1/20
⇒ 13/1440
∴ अर्धी टाकी 720/13 मिनिटे किंवा \(55\frac{5}{13}\;\) मिनिटांत भरली जाईल.Last updated on Jul 18, 2025
