There are 600 tennis players
4% wear wrist band on one wrist
Of the remaining, 25% wear wrist bands on both hands
How many players don't wear a wrist band?

• 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.
