A watch loses 10 seconds for every 30 minutes. If it was set right at 6 hrs on Monday.
We have to find the time that will show the following Monday at 6 hrs.
Total time duration between two successive Monday at 6hrs = 7 days
= 7 × 24 hrs = 168 hrs
Here, The watch loses 10 seconds for every 30 minutes.
∴ It loses 20 seconds for every 1 hour.
∴ It loses 20 × 168 = 3360 seconds for 168 hrs.
Hence, losing time = 3360 seconds = 3360/60 = 56 minutes
so the actual time will show the following Monday at 6 hrs = 6 : 56 am.
Therefore the time will show the following Monday at 6hrs is 6 : 56 am.
