Question 1018525
 a clock gains 10 minute in every 24 hours .
it is set right on Monday at 8am
 what will be the correct time on the following Wednesday, when the watch indicates 6 pm?
:
We can say the clock gains 10/24 = 5/12 min every hr
On Wednesday the elapsed time of the clock will be: 24+24+10 = 58 hrs 
In 58 hrs it has gained 58 * 5/12 = 24.167 minutes
therefore the actual time when it says 6 pm:

60 - 24.167 = 5:35.83 or 5 hr 35' 50"
