Given : Vinit bought a new wall clock on Monday and set the correct time as 10 am on it and fixed it on a wall
The same clock loses 15 minutes in 24 hours
To Find : What will be the true time if the clock indicates 4a.m
on the following Sunday?
6:00 a.m.
5:02 am
4:44 a.m
5:12 a.m.
6:43 a.m.
Solution:
clock loses 15 minutes in 24 hours
=> Clock shows 23 .75 hrs in actual 24 hrs
10 AM Monday to 4a.m on the following Sunday
=> 24 * 6 - 6 = 138 hrs
Clock shows 138 hrs
Clock shows 23 .75 hrs in actual 24 hrs
=> Clock shows 23 .75 hrs in actual 24/23.75 hrs
=> Clock shows 138 in actual 138 * 24/23.75 hrs
= 139.45 hrs
Hence 1 . 45 hrs = 1 hr + 27 mins
Hence 5 : 27 will be time
