Two boats in two parallel canals started at the same time in the same direction from the same place. One is travelling upstream and the other is travelling downstream. If both the boats reach the finish line at the same time, the boat speed in still water of upstream travelling 'x' and the speed boat in still water of downstream travelling boat 'y' if the speed of the stream in both canals is 10 km/hr and the sum of their speeds is 40km/hr. The possible value of x and y दो समानांतर नहरों में दो नाव उसी स्थान से उसी दिशा में एक ही समय में चलना प्रारंभ किया एक उर्ध्वप्रवाह जा रही है और दूसरी अनुप्रवाह , दोनों नावे एक साथ फिनिस बिंदु पर पहुचती हैं, उर्घ्व प्रवाह चलने वाली नाव की शांत जल में चाल 'x' और अनुप्रवाह चलने वाली नाव की शांत जल में चाल 'y' है, यदि दोनों नहरों में धारा की गति 10 किमी/घंटा है और नावों की गति का योग 40 किमी/घंटा है तो. x और y का संभावित मान है- a) 30 , 20 b) 30, 10 c) 20 ,10 d) 10 , 20
