Question

How much does a watch lose per day, if it's hands coincide every 64 minutes

Answer 1

See as it is a clock its hands should coincide every 60 mins but its coinciding in every 64 mins that means its losing 4 mins every hour. Since we have 24 hrs in a day it will lose

24*4 mins= 96 mins every day or 1 hr 36 mins every day
