At a circus fair their was a booth, where you had to guess the amount of balls in each cup. Their were four cups. They all had the same amount.In front of each cup it said how many balls were in each. In front of the first - "One or four", the second - "Two or one". The third- "Three of four." The fourth- "Two or four". Only one statement was true. How many balls were their in total?

Spoiler for solution

(i know how this can sound sexual, so you don't need to comment on that, i just did.)

Most of them in here require pictures, but I'll search for some that don't.

Change the signs on the cups to their opposite.

Three negated signs are true.
The correct number is thus named three times, on cups 1, 2 and 4.
Couldn't be much simpler than that.

I know, but that you explained yourself in your first post in this thread confused me is all.
