Show answer & explanation
Correct answer: A
Solution:
Given the mirror image shows 2:16 on a 24-hour clock. For a 24-hour clock, the actual time is obtained by subtracting the mirror reading from 23:60 (i.e., hours = 23 − H, minutes = 60 − M), borrowing an hour if needed.
Mirror reading hours = 2, minutes = 16.
Subtract minutes: 60 − 16 = 44 minutes.
Subtract hours: 23 − 2 = 21 hours.
Combine the results to get the actual time: 21:44.
Note: If the minutes subtraction required borrowing (for example if mirror minutes were 0), subtract one additional hour from the hour result and adjust minutes accordingly. The general formulas are: for 12-hour clocks subtract from 11:60, and for 24-hour clocks subtract from 23:60.
