So, the answer to this mind puzzle is that the clock will show the time 12:20 after 90 degrees anticlockwise rotation. This brain puzzle is just another fun way to test your IQ.

It's easy to rotate a picture on your iPhone directly in the Photos app. You can rotate a picture at a 90-degree angle, automatically turning it on its side or flipping the photo upside down.

Your Chromebook’s screen should rotate 90 degrees every time you put it in tablet mode — in other words, when you fold the keyboard back or remove it and hold the device like a tablet.
