If the number of female players is 5, the number of male players is 5 × (1+ 1.5) = winner; if the average score of male players is X, the average score of female players is X × (1+20%) =1.2x;

( 1.2x)×5+ x=75×(5+)，

& nbleft p; & nbleft p; & nbleft p; & nbleft p; & nbleft p; & nbleft p; & nbleft p; & nbleft p; Get x+, get x=825,
