- At 5 O' clock the minute hand is 25min spaces behind the hour hand
case 1 :- Minute hand is 6min spaces behind of the hour hand
In this case , the minute hand has to gain (25-6) = 19minute spaces
55 min spaces are gained in 60 min
19 min spaces are gained in [(19/55) * 60] = (20) 8/11 min.
case 1 :- Minute hand is 6min spaces behind of the hour hand
In this case , the minute hand has to gain (25-6) = 19minute spaces
55 min spaces are gained in 60 min
19 min spaces are gained in [(19/55) * 60] = (20) 8/11 min.
case 2 :- Minute hand is 6min spaces ahead of the hour hand
In this case , the minute hand has to gain (25+6) = 31minute spaces
55 min spaces are gained in 60 min
31 min spaces are gained in [(31/55) * 60] = (33) 9/11 min.

- minute hand should travel 19 mis or 31 mins to have gape of 6 mins...so in case of 19 mins (19*60/55) and in case of 31 mins (31*60/55) will be the ans...for above question c is ans...i.e 20*8/11

- when clock is at 5 o'clock minute hand and hour hand is 25 minutes space apart. to be 6 minutes space apart the minute hand should be at 19 minutes. so for 55minutes spaces are gained at 60 min.
so 6 min will be gain at (60/55)*6. so option (b) is the answer. - 8 years agoHelpfull: Yes(3) No(2)
- 1min-->6deg
6min-->36 deg
5*30=150 deg....but both are 6 min apart it means 150-36=114 deg distance
T=d/s=114/(11/2)=228/11=20 8/11..ans is C - 8 years agoHelpfull: Yes(2) No(0)
