6. Let XX be the set of natural numbers divisible by 100, YY be the set of natural numbers divisible by 25, ZZ be the set of natural numbers which are perfect squares. Now consider the following Venn diagram. [Note: A,B,C,D,E,F,GA,B,C,D,E,F,G are the region marked in the following Venn diagram (A region in the Venn-diagram can be an empty). For example, A=X∖(Y∪Z),B=Y∖(X∪Z),andC=Z∖(X∪Y)A=X∖(Y∪Z),B=Y∖(X∪Z),andC=Z∖(X∪Y).]
