Question

A Clock is set right at 7 AM, and the clock loses 15 min in 24 hrs. What is the correct time when it shows 4 PM. after 2 Days. (a) 4:32 PM (b) 4:30 PM (c) 4:36 PM (d) 4:35 PM​

Answer 1

Answer:

after 2 days when clock shows 7AM exact time is 7:30AM

and from 7AM-4PM there are 9 hours

In one hour clock loses 15min/24hour=0.625min/hour

so in 9 hour clock loses time = 0.625*9

= 5.625 min

when we multiply 0.625*60=37.5seconds

so when clock shows 4PM after 2 days correct time is 4:35
