Minute hand overlaps hour hand in 65 mins. In how many days it will gain 1440 hours ?
Answer: C. 60 days
In this problem , it has considered that 65 mins = 1hr So mins has increased by 5 mins so multiply 5 x 24 = 120 mins extra , That is now per day it adds 2hr extra, so divide 1440/26 = 59.384 days =~ 60 days.
