Let the speed of the boat be u and that of the stream be v. Then, speed of boat downstream = u + v And speed of boat upstream = u – v From I u + v = 18/3 = 6 km/hr ……….. (i) From II, u – v = 18/6 = 3 km/hr ……… (ii) From statement III, v = u/3 ……….(iii) From I and II, we get u = 9/2 = 4.5 km/hr. From I and III, we get u + u/3 = 6 Or 4u = 18 u = 4.5 km/hr. Hence statement I and either II or III is sufficient to answer the question.
