    Question

    What is the speed of boat in still water?

    Statement I: It takes the boat thrice as much time to row up than as to row down the same distance in the river. Statement II: Speed of water is 2kmph. Statement III: The boat can cover 30 km upstream distance in 10 hours. In each of the following questions, a question is followed by three statements numbered I, II and III. Read all the statements and answer accordingly.
    A I and III together Correct Answer Incorrect Answer
    B Only II Correct Answer Incorrect Answer
    C I and II together Correct Answer Incorrect Answer
    D I and either II or III Correct Answer Incorrect Answer
    E Any combination of 2 statements can give the required result Correct Answer Incorrect Answer

    Solution

    Let speed of boat = u, and stream = v From U/V=N+1/N-1=3+1/3-1=4/2=2 From II: v = 2 From III: u – v = 30/10 = 3 So solving I and II ‘u’ can be found. Similarly by solving II and III and by solving I and III
