17 wins 3 losses =20 games
2/3x=20, x=30
3/4*30=22.5/30
cant lose .5 games so 23/30 is maximum losses
so can lose up to 7 games, already lost 3, that leaves 4 left

I think this has been discussed earlier.
Games played till now=17+3=20. this is 2/3 of total games
So total games to be played=3/2*20=30
Condition is winning at least 3/4 of all games 3/4 *30 is 21 (at least)[ games already won=17 so left for winning =21-17=4

We should consider 23 instead of 22.5 for the games that players should win.
Answer=4
