Answer:
c)12min
Step-by-step explanation:
given that at 8 am, both are showing correct time.
given,1st clock looses 2min an hour and 2nd clock gains one minute an hour,
that means at 12 noon,1st clock time will be 4hrs -8mins from 8am,that means time will be 11:52 am in 1st clock.
at 12 noon,2nd clock time will be 4hrs+4mins from 8 am,that means time will be 12:04 pm in 2nd clock.
therefore,the difference between the clocks will be 12 mins.
Hope u understand...
