    E If the data in both the statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer

    Solution

    From statement I , distance/speed = time And if twice speed then distance/(2 × speed) = 30 Solving both equations, we can find time. From statement II, we also require distance to know the time.
