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%

77.72%
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%
