Detailed Solution

The above statement is false.
Since a plane mirror creates a laterally reversed image, Ashok's time measurement is incorrect. The clockwise watch is changed into the anticlockwise watch depicted in the illustration due to its reflection in a flat mirror. The Plane mirror always forms an image inverted. The clock shows the time as it should be

8 h 25 \min .

Correct statement would be Ashok observes the time as

4 hr 35 \min

, as shown in the adjoining figure when he looks at the image of the clock formed by a plane mirror and in real time would be

8 h 25 \min .
