Answer Posted / p praveen
The time travelled by wrong clock is 27.25hrs in 27hrs.
So Speed of wrong clock is 27.25/27.
Let 'x' hrs be the number of hrs after which it shows the
correct time.
Speed of wrong clock at the correct time=distance
travelled/speed=(x+5/60)/x=27.25/27
Which implies that x=9hrs
Therefore watch showed the correct time at 3+9=12:00 AM
