Answer: Option B

Explanation:

Loss time for every day 10 min

Loss time for 6 days is 6×10 min = 60 min = 1 hours

i.e For every 6 days hour hand clock back 1 h

We know there are 12h in a clock

If the chock 12 backed then it will give us real time

So required time for showing real time is = 6×12 = 72 days

Ans. 72 days
