A clock is such that it loses 4 minutes each day. The clock is set right on February 25, 2008 at 2 p.m. How many minutes should be added to get the right time when the clock shows 9 a.m. on 3rd March, 2008?
Actual time passed = (6 days * 24 hours) + 19 hours = 163 hours.
given: Clock losses 4 minute in every single day.
(i.e.) In 1440 minutes (24hours * 60 minutes) it losses 4 minutes.
Therefore, the minute hand moves at a slightly slower manner.
That is, the speed of minute hand can be expressed as 1436/1440 fractional part of one minute.
Actual time elapsed is just the reciprocal of it. (i.e.) 1440/1436
Thus in the given time of 163 hours, the actual time elapsed
= 163 (hours) * 60 (minutes) * 1440/1436 (minutes hand)
But due to loss in time, the time elapsed by clock is different and = 163*60
Now calculate the difference = (163*60*1440/1436) – (163*60) = 9780/359
