clock will show the same time after 24 hours
since loss of 5 min in 1 hour
so loss of 60min(1 hr) in 12 hour
so loss of 24 hr in 12*24 hour=12 days
after loss of 24 hr it will again at 8 AM after 12 days
i.e at 8 AM on sunday
ans(b)

For the watch to show the correct time again, it should lose 12 hours.

It loses 5 minutes in 1 hour

=> It loses 1 minute in 12 minutes

=> It will lose 12 hours (or 720 minutes) in 720*12 minutes = 144 hours = 6 days

=> It will show the correct time again at 8 AM on Sunday
