If a water image shows 10:55 in a clock, then what will be the actual timing?

For every water image based on a clock,

If minutes are less than 30, then subtract given timing from 18:30 hrs.

If minutes are more than 30, then subtract given timing from 18:90 hrs.

Here minutes are more than 30. So, 18:90 - 10:55 = 8:35

Hence, actual time will be 8:35.
