At what time between 1'O clock and 2'O clock the hands of the clock are opposite to each other.
-
- 34(6/11) past 1'Oclock
- 38(2/11)past 1'Oclock
- 56(8/11)past 1'Oclock
- 64(9/11)past 1'Oclock
Correct Option: B
The minute hand to coincide with the hour hand it should trace at first 5 minute spaces and then the hands of the clocks to be opposite to each other minute hand should trace 30 minute spaces i.e. totally it should gain 5 + 30 = 35 minute spaces to be opposite to that of hour hand.
We know that, Minute hand gains 55 minute spaces over hour hand in 1 hour. Therefore, Minute hand gain 40 minute spaces over hand in 35 x (60/55) = 38(2/11).
Hence the hand of the clock will minutes be opposite to each at 38 (2/11) past 1'O clock. Therefore, Correct option is B.
