If you carefully examine the picture, you can figure out how many people are actually inside. If your answer is 11, that’s incorrect, as both the picture and the statue are lifeless.

Similarly, if you think there are 5 people, you’re also mistaken because there’s someone hiding behind the picture in the room. Therefore, the correct answer is that there are 6 people inside the gallery.

To clarify, if you take a closer look at the person labeled as number 6 in the image below, you’ll notice something unusual—the eyes of this figure are different from the other portraits on the wall.

The eye area of picture number 6 has been cut out, revealing a person standing behind it.
