Correct Answer: 7:45 in the next morning
Explanation:
We know that the time difference between India and USA is 9 hrs 30 min.
India is 9:30 hrs ahead of USA.
Time in India = 4:15 + 9:30 = 13:45 PM.
Required Time after 18 hrs = 13:45 + 18 hrs = 7:45 AM.
Hence it is 7:45 AM on the next morning.
Correct Answer: 10
Explanation:
Angle traced by hour hand in hrs = =
Angle traced by min. hand in 20 min = =
Required angle = (130 - 120)º = 10º

point to be remembered
Correct Answer: 22
Explanation:
The hands of a clock coincide 11 times in every 12 hours (Since between 11 and 1, they

The hands overlap about every 65 minutes, not every 60 minutes.
The hands coincide 22 times in a day.
Correct Answer: 3:49 1/11
Explanation:
On straight line means 180 degree angle.
180 = 11/2 min ? 30 hrs
180 = 11/2 m ? 30 × 3
180 = 11/2 m ? 90
(180 + 90) 2 = 11 m
m = 540/11 = 49 1/11 minutes.
Correct Answer: 30
Correct Answer: 130
