The two hands of a clock will be together between h and (h+1) o'clock at
Answer: A
At h o' clock, the minutes hand is 5 h minute spaces
behind the hour hand.
The minute hand gains 55 min spaces in 60 mins.
∴ The minute hand will gain 5h minute spaces
in 60/55 * 5h = 60h/11 minutes.
∴ The two hands will be together between
'h' and 'h+1' o' clock at (60/11)h minutes h o' clock.
