Answer: Option BExplanation:Solution 1If the minute hand of a clock overtakes the hour hand at intervals of MM minutes of correct time, the clock gains or loses in a day by(72011−M)(60×24M)(72011−M)(60×24M) minutesHere M = 64. The clock gains or losses in a day by=(72011−M)(60×24M) =(72011−64)(60×2464) =1611(60×38) =211(60×3) =36011=32811 minutes=(72011−M)(60×24M) =(72011−64)(60×2464) =1611(60×38) =211(60×3) =36011=32811 minutes
