There are 600 tennis players
4% wear wrist band on one wrist
Remaining players = 600*0.96 = 576
Of the remaining, 25% wear wrist bands on both hands
and Of the remaining, 75% do not wear wrist bands .
so players not wearing wrist bands = 0.75*576 = 576*3/4 = 144*3 = 432

There are 600 tennis players
among them 4% wears wrist watch on one wrist
so,no of tennis players wearing wrist band on one wrist=600*(4/100)=24
now remaining players=600-24=576
now, given that of the reamining 25% wears wrist bands on both hands=576*(25/100)=144
so total players weraing wrist bands=144+24=168
hence, no of players not wearing any wrist band=600-168=432

the ans is 432.
