Given : a clock was correct at 2 pm but then it began to lose 30 minutes each hour.
it now shows 6pm, but it stopped 3hrs ago.
To Find : correct time now
Solution:
a clock was correct at 2 pm
Clock shows 6 pm
hence clock time = 6 - 2 = 4 hrs
it began to lose 30 minutes each hour.
for every 1 hour , clock show only 1/2 hour
for 1/2 hour of clock , actual time is 1 hr
=> for every 1 hour of clock , actual time is 2 hr
=> for 4 hour of clock , actual time is 4 * 2 = 8 hr
2 PM + 8 hr = 10 PM
but it stopped 3hrs ago
=> 10 PM + 3 = 1 AM Next Day
correct time now 1 AM Next Day
