Question

If in a mirror a clock shows time as 12 : 40, then the real time is:-

1.

11 : 20

2.

10 : 10

3.

8 : 10

4.

12 : 40

Answer 1

Correct Answer - Option 1 :

11 : 20

Given time in the clock in mirror = 12 : 40.

Real time + Mirror time = 24 : 00.

Real time = 24 : 00 - Mirror image time

24 : 00 can be considered as 23 : 60 because it will simplify the subtraction process.

Real time = 23 : 60 - 12 : 40

Real time = 11: 20    (Here, decimal cycle is of 60, as 60 minutes = 1 hour).

Hence, the correct answer is  "11 : 20".
