    we should calculate senior to senior, women to women, senior to women and then we should sum then all and then we should eject something from this result,, but what?

    1 persons shakes 200 hands; 200 another person shakes the same hands; +200 another person shakes the same hands; +200 100 people shake the same 200 hands: 100(200) = 20000 handshakes for that part
