- answer is 500 !!
let the number of the total student is x ..
so, for sports = 12x/100 students ;
for dancing = 3x/4 = (75x/100) students ;
for singing = (10x/100) students ;
so, x - {(12x/100)+(75x/100)+(10x/100)}=15;
by solution.. (3x/100)=15 ;
x=500 (ans.)!!! - 12 years agoHelpfull: Yes(4) No(0)
