Question

A person has mistaken the image of a clock in a plain mirror as the clock and read the time as 6:10. What was the correct time?

• A. 6:50
• B. 5:50
• C. 5:10
• D. 7:50
• E. None

Answer 1

Answer: (B)

5:50

Assume that there is a line drawn between 12 and 6 on the clock, this can be a line of symmetry.
When we take the mirror image of this clock, the hands that are on the right side of this line will appear equidistant on the left side of the line and vice versa.
The time indicated is 6:10, the hour hand a little after 6 and the minute hand on 2.
Its mirror image will become, the hour hand a little before 6 and the minute hand on 10, i.e, 5:50.
