“Who is the billionaire? The mystery that fools 90% of people”

The image shows four hands, numbered 1 to 4, each with different details, in front of a golden curtain, like a competition. Hand 1:
Wearing a gold Rolex watch + a large ring with a huge yellow stone. Looks “very rich.” Hand 2:
An ordinary hand. No watch, no ring, nothing. Looks “ordinary.” Hand 3:
Wearing a very luxurious mechanical watch that looks like it’s worth millions + holding a Rolls Royce key. Looks “the richest one.” Hand 4:
Wearing two diamond bracelets + a gold ring. Looks “stylish and elegant.” The question above is: WHO IS A BILLIONAIRE? = Who is the billionaire? The answer and the trick: Most people will say 3 because he has a Rolls Royce key and an expensive watch.
