    How many times are the hands of a clock at right angles in a day?     

    A) 24        

    B)                           48        

    C) 22                                

    D) 44

    E) None of these

    Correct Answer: D

    Solution :

    Explanation Option [d] is correct. We know that hands of a clock are at right angle twice in every hour but two positions of the hands of clock i.e., at 3 o?clock and 9 o?clock are identical. So, they are at right angles 22 times in 12 hours and therefore, in 24 hours or in a day they are at right angle 44 times. So, the correct answer is (d).
