A clock loses 1% time during the first week and then gains 2% time during the next one week. If the clock was set right at 12 noon on a Sunday, what will be the time shown by the clock exactly 14 days from the time it was set right?	Choose the correct choice from the following answers
A) 1: 36: 48  B) 1: 40: 48  C) 1: 41: 24  D) 10: 19: 12  E) None
Solution:   The clock loses 1% 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=

<output>168</output>
168 hours in a week.   If the clock loses 1% time during the first week, then it will show a time which is 1% of 168 hours less than 12 Noon at the end of the first week= 1.68 hours less.   Subsequently, the clock gains 2% during the next week. The second week has 168 hours and the clock gains 2% time = 2% of 168 hours = 3.36 hours more than the actual time.   As it lost 1.68 hours during the first week and then gained 3.36 hours during the next week, the net result will be a   -1.68 + 3.36= 
<gadget id="calculator">  -1.68 + 3.36</gadget>
<output>1.68</output>
1.68 hour net gain in time.   So the clock will show a time which is 1.68 hours more than 12 Noon two weeks from the time it was set right.   1.68 hours= 1 hour and 40.8 minutes = 1 hour + 40 minutes + 48 seconds.   i.e. 1 : 40 : 48 P.M.   Answer 1: 40: 48
<result>B</result>
