In a class the ratio of boys n girls is 5:6.if 25% of boys n 20% of girls r scholarship holders,find the %of students who r not scholarship holders?

• 500:600
  25/100*(500)+20/100*(600)=125+120
  =245 (scholarship holders)
  non scholarship holders=1100-245
  =845
  so,
  (100/1100)*(845)=77.77%
  77.77% of students are not scholarship holders

  Let total students be x
  
  No. of boys = 5/11*x
  No. of girls = 6/11*x
  
  Total no. of scholarship holders = 25/100*5/11*x + 20/100*6/11*x
  =5/44*x + 6/55*x
  
  Total no of students = No. of scholarship holders + No. of students who are not scholarship holders
  
  x = 5/44*x + 6/55*x + No. of students who are not scholarship holders
  
  No. of students who are not scholarship holders = 171/220*x=0.777x
  
  % of students who are not scholarship holders = 0.777x/x*100
  =77.7%

• B:G=5:6 i.e., 500:600
  (25*500/100)+(20*600/100)=245
  so non scholarship students are 1100-245=855 i.e.,77.72%

• 5/6 means 45% boys 55% girls
  25% of 45 is 11%
  20% of 55 is 11% so who r not scholarship holders = 100-11-11=78 % (approx)

• Boys : girls ratio ==> 5 : 6
  Total students = 5x + 6x = 11x
  boys holding scholarship = 5x * 25/100 => 5x/4
  girls holding scholarship = 6x * 20/100 = 6x/5
  
  students not holding scholarship = 11x - [5x/4 + 6x/5]
  => 174x/20
  % of student not getting scholarship = 174x*100/20*11x = 79%
  
  Ans : 79%

• b:g=5:6
  so b non scholarship are=100-25=75
  g non scholarship are= 100-20= 80
  by formulA= b*75+g*80/b+g
  =5*75+6*80/11=77.7
