Show answer & explanation
Correct answer: C
Solution
For every mirror image based on a clock,
Given :
The clock shows the time = 4:20
To find :
Time is shown in the mirror image
Concept used :
For mirror image
(11 - hours) : (60 - minutes)
Solution :
Hours = 4
Minutes = 20
Mirror image = (11 - 4) : (60 - 20)
⇒ Mirror image = 7:40
Additional Information
If it is 12 hrs clock, then subtract the given timing from 11:60 hrs.
If it is 24 hrs clock, then subtract the given timing from 23:60 hrs.
Hence, the real time will be 7:40.
