    at the right angles?
    A 43*5/11 minutes past 3 Correct Answer Incorrect Answer
    B 56*2/11 minutes past 3 Correct Answer Incorrect Answer
    C 32*8/11 minutes past 3 Correct Answer Incorrect Answer
    D 65*7/11 minutes past 3 Correct Answer Incorrect Answer

    Solution

    At 3 o’clock the hands are at 15 minutes spaces apart. To be at the right angles and that too between 3:30 and 4, the minute hand has to gain (15 +15) = 30 minutes = 60/55×30 = 32*8/11 minutes ∴ Required time = 32*8/11 minutes past 3.
