A clock shows 9:00 AM. Then the correct time in the water is :

  • A.9:30 AM
  • B.9:00 AM
  • C.3 AM
  • D.3:30 AM

Answer: A

The time seen in the water is 9:30 AM.

A water image flips the clock top to bottom. The minute hand at 12 appears at 6, and the hour hand at 9, which lies on the horizontal line, stays at 9. So the image shows the hands at 9 and 6, which reads as 9:30.

A quick rule for water images is to subtract the time from 18:30; here \(18{:}30 - 9{:}00 = 9{:}30\). 3 AM is what a mirror (left-right) image of 9:00 shows, 3:30 AM matches neither image, and 9:00 would mean no reflection at all.
