Let 'b' be the number of boys and 'g' be the number of girls

bC2 =45
b(b-1)/2 =45

b(b-1) = 10*9
b=10

gC2 = 190
g(g-1) = 380
g(g-1) =20*19
g =20

The total no of games = 30C2 = 30*29/2 = 435

The number of games in which one player was a boy and the other was a girl = 435-190-45 =200 (it is the same as 20C1*10C1)

B= boys G=girls. BC2=190 => B=20 , GC2=45 => G=10, total players 20 + 10 = 30

Matches between single boy and single girl = 20C1*10C1 = 200
