The question consists of two statements numbered “I and II” given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.
In a certain stream flowing at a speed of 5 km/hr, boat 'N' takes 'r' minutes to travel 91 km upstream Find the value of 'r'. [Also, r < 800]
Statement (I): In 'r' minutes, boat 'Z' can travel 97.5 km in still water. In a stream flowing at a speed of 5 km/hr, the downstream speed of boat 'Z' will be 25% more than the upstream speed of boat 'N'.
Statement (II): In a stream flowing at a speed of 2 km/hr, boat ''N' takes 1 hour more to travel 105 km downstream than it takes to cover a distance of 62 km upstream.
