Question - 20
In this difficult puzzle-conundrum there are fifteen circles, each of which is divided into three parts. Parts of the circle can be painted in two different colors. Guess by what rule the colors of the paint in the circle segments are formed. Choose the appropriate option to replace the question mark.
The correct answer is 4.
Here, each circle is divided into 3 parts: right, left and bottom. The bottom row of circles is considered first. Let's take any two circles standing next to each other. If some part of both circles is painted only dark or only light, then in the circle located higher in the center of these two circles, this same part of the circle is painted light. If in one circle some part was painted light, and in the other circle this same part was painted dark, then in the circle located higher, this same part of the circle is painted dark. Thus, you need to move from the bottom up to the top.
