In the following questions, two quantities are given as Quantity I and Quantity II. Find the correct relationship among them. Quantity I: Three pipes P, Q and R are attached to a tank. Pipe P alone and Pipe Q alone can fill the tank in 30 hours and 20 hours respectively. If pipe P opened for 10 hours and closed, then pipe Q opened for 5 hours and closed and pipe R alone can fill the remaining tank in 5 hours. How many time pipe R alone take to fill the whole tank? Quantity II: Three pipes A, B and C can fill a tank in 10 hours. After working at it together for 3 hours, C is closed and A and B can fill the remaining part in 14 hours. How much time taken by C to fill the tank alone? निम्नलिखित प्रश्नों में, दो मात्राएँ मात्रा I और मात्रा II के रूप में दी गई हैं। इन मात्राओं के बीच सही सम्बन्ध ज्ञात कीजिये। मात्रा I: एक टंकी से तीन पाइप P, Q और R संलग्न हैं । पाइप P अकेले और पाइप Q अकेले 30 घंटे और 20 घंटे में क्रमशः टैंक भर सकते हैं। यदि पाइप P 10 घंटे के लिए खोला गया और फिर बंद कर दिया गया, उसके बाद पाइप Q 5 घंटे के लिए खोला गया और फिर बंद कर दिया गया और पाइप R अकेले 5 घंटे में शेष टैंक को भर सकता है। पूरे टैंक को भरने के लिए अकेले R कितना समय लेगा? मात्रा II: तीन पाइप A, B और C 10 घंटे में एक टंकी भर सकते हैं। 3 घंटे के लिए एक साथ काम करने के बाद, C बंद कर दिया जाता है और A और B शेष भाग को 14 घंटों में भर सकते है। अकेले C टैंक भरने के लिए कितना समय लेगा?
