in a school the ratio of boys and girls are in the ration 5:6 .25% of boys will get scholar ship and 20% of girls will get scholar ship what % of students wont get scholarship?

• Boys : Girls => 5x : 6x
  Total no. of students including boys nd girls = 5x+6x = 11x
  
  25% of boys => 5x*25/100 = 5x/4
  20% of girls => 6x*20/100 =6x/5
  No. of students who are getting scholarship => 5x/4 + 6x/5 = 49x/20
  No. of students who are not getting scholarship = 11x - 49x/20 = 171x/20
  
  % of students not getting scolorship => 171x/20/11x * 100
  => 100*171x/220x
  = 77.7%
  
  Ans : 77.7% (or) 78%

  If there are 5x boys and 6x girls.. total students=11x
  % of students wont get scholarship = 100*(5x*0.75+6x*0.8)/11x = 855/11= 77.72%

  25%of5=1.25
