The ratio of number of boys to that of girls in a school is 3:2.if 20% of boys and 25 % of girls are scholarship holders,find the percentage of those who are not scholarship holders.

• since ratio be 3:2 let there is 100 students so there are 60 boys and 40 girls.so 60/40=3:2.now we find 80% of boys who are not scholarship holder so 80% of 60 is 48.now we find out 75% of girls who are not scholarship holder so 75% of 40 is 30.
  
  so total number who are not scholarship holder is 48+30=78

• ratio of boys n girls=3x:2x
  total boys, those who are not scholarship holder=3x/5x*80=48
  total girls, those who are not scholarship holder=2x/5x*75=30
  so, 48+30=78

• Boys = 3x, girls = 2x,
  No of students holding scholarship is boys= 0.75x, girls = 0.5x
  % of students not holding scholarship is, ((2.25x+1.5x)/5x)*100= 75%
• 11 years agoHelpfull: Yes(1) No(10)
• 78% le boys be 3x and girls be 2x total non scholarship holders (240x + 150x)/100
  total boys and girls 5x
  so 78 %

• Ans 8:5
  boys suppose 3x
  girls 2x
  non scholership boys (3x-(3x*20/100)):non scholershipholder girls (2x-(2x*25/100))
• 11 years agoHelpfull: Yes(0) No(0)
• let x= no.of students
  boys=3x
  girls=2x
  total students=5x
  20% of 3x=3x/5
  25% of 2x=x/2
  scholarship holders=3x/5+x/2=11x/10
  non scholarship holders=5x-11x/10=39x/10
  so % of those=(39x/10)/5x*100=78
