One day, Piyush observed the time in the mirror image of the clock as 4 hours and 40 minutes. What is the actual time shown by the clock?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 7 hours 20 minutes
A mirror reverses left and right, so each hand appears as far on the other side of the 12 as it really is on its own side. The real time and the mirror time therefore add up to 12:00, written as 11:60 when minutes have to be taken away.
Mirror time: 4:40
Real time \(=\) 11:60 \(-\) 4:40 \(=\) 7:20
In the picture the hour hand is blue and the minute hand amber on both clocks: each hand jumps to the other side of the 12–6 line.
