When seen through a mirror, an analog clock shows quarter to four. The correct time shows by the clock:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 8:15
Step 1: Concept
- When an analog clock is seen in a mirror, the time is reflected about the vertical axis.
- The mirror image time can be found by:
$\text{Mirror time} = 12:00 - \text{actual time} \quad (\text{on a 12-hour clock})$
Or equivalently:
$\text{Actual time} = 12:00 - \text{Mirror time}$
Step 2: Mirror shows quarter to 4
- “Quarter to 4” = 3:45
$\text{Actual time} = 12:00 - 3:45$
- Subtract 3:45 from 12:00:
$12:00 - 3:45 = 8:15$
