Question 6:

On a sunny day, a boat can cover 84 km in still water or 112 km in downstream is 3 hour 30 minutes. On a rainy day the speed of the stream is increased by 50% whereas due to low validity the speed of the boat is decreased by 25%. Find the time taken by the boat to cover 27 km upstream and 90 km downstream on a rainy day. एक धूप के दिन, एक नाव शांत जल में 84 किमी की दूरी तय कर सकती है या धारा की विपरीत दिशा में 112 किमी की दूरी 3 घंटे 30 मिनट है। बारिश के दिन धारा की गति 50% बढ़ जाती है, जबकि कम वैधता के कारण नाव की गति 25% कम हो जाती है। एक बारिश के दिन 27 किमी धारा की विपरीत दिशा में और 90 किमी धारा की दिशा में जाने के लिए नाव द्वारा लिया गया समय ज्ञात करें।
