1. 10 men and 10 women ar e there, they dance with each other, is there possibility that 2 men are dancing with same women and vice versa?
a) 22
b) 20
c) 10
d) none

• Since all are dancing in pairs and women and men are equal in number, if 2 men are dancing with the same women there will be 8 others men and 9 other women left to form pairs. Hence one women will not be able to dance which contradicts the data given that they all dance in pairs. Thus the answer is option d)none.
