A clock gains 2% time during the first week and then loses 2% time during the next one week. If the clock was set right at 12 noon on a Wednesday, what will be the time that the clock will show exactly 14 days from the time it was set right?
Answers
Answer:
The clock gains 2% time during the first week. In a day there are 24 hours and in a week there are 7 days. Therefore, there are 7 * 24 = 168 hours in a week.
If the clock gains 2% time during the first week, then it will show a time which is 2% of 168 hours more than 12 Noon on next Wednesday (end of first week) = 3.36 hours more.
Subsequently, the clock loses 2% during the next week. The second week again has 168 hours and the clock loses 2% time = 2% of 168 hours = 3.36 hours less than the actual time.
As it gained 3.36 hours during the first week and then lost 3.36 hours during the next week, the net result will be a -3.36 + 3.36 = 0 hour net gain in time.
So the clock will show a time, which is exactly 12 Noon on Wednesday two weeks from the time it was set right.
