My friend gave me this problem, and I don't know how to solve it.

Pattern have been laid and it consist of 11/32 of black.

The pattern consist of 20 of Figure 1.

Figure 1 consist of 3/6 (1/2) black and 3/6 (1/2) white.

The pattern also consist of Figure 2.

Figure 2 consist of 1/4 black and 3/4 white.

How many of Figure 2 is in the pattern?

I have tried for almost an half an hour now. I feel really stupid.

Please help me.
