Correct time at 7:44 AM on the 6th of the month
Explanation:
Day 6
4:00 AM - 12 min slow
Day 10
6:00 PM - 20 mins fast
change in time = 12+20 = 32 min
4:00 AM, day 6 to 4:00AM, day 10 = 24*4=96hrs
day 10 : 4AM to 6PM = 14 hrs
Total hrs from day 6 to 10 = 96+14=110hrs
Now, we see a change of 32 mins in 110 hrs
rate of change: 110/32= 3 hr 44 mins
therefore:
4:00 AM + 3 hr 44 min = 7:44 AM
:)
