- Total hours from Monday 10.00 AM to Friday 3.00 PM =101 HOURS
The clock loses 6 minutes every hour. In 101 hours it will lose 101 x 6 =606 minutes. ie 10 hours 06 minutes.
To find the actual time, calculate 10 hours 6 min backwards from Friday 3.00 PM which is 4 .54 AM
Hence the actual time would be 4 .54 AM when clock shows 3.00 PM on Friday. - 8 years agoHelpfull: Yes(6) No(9)

- Total time passed in the faulty clock = Monday 10 am to Friday 3 pm = 24 x 4 + 5 hours = 96 and 5 hours = 101 hrs
54 min in the faulty clock = 60 minutes of the correct clock
101 hrs in the faulty clock = ?
10154×60 = 112.2 Hrs.
96 Hrs + 16.2 Hrs
Friday 10 am + 16 hrs = Saturday 2am
0.2 x 60 min = 12 min
So Saturday 2.12 min AM

- Let us start from Monday 10 am to friday 3.00 pm , total hours = 4 days 5 hrs(4*24+5 = 101 hrs).
Clock lose per hour = 6 min, so total time loses is 101 * 6minutes = 606 minutes (10 hrs 10 minutes ).
So actual time = Friday 3.00 pm + 10 hrs 10 minutes = saturday 1.10 am. - 2 years agoHelpfull: Yes(0) No(0)
