- In the given question the ratio of the boys and girls is 5 : 6.
- Where, 25% boys will be getting the scholarship.
- And, 20% of girls will be getting the scholarship.
- The % of students will not get the scholarship.
- Here, it is that the ratio of boys and girls is 5 : 6
Lets assume that the no. of boys and girls are :
➠ 5x and 6x respectively.
Then, Total no. of students will be :
➠ 5x + 6x = 11x
Now,
Where,
➠ No. of boys are = 5x
➠ % of boys getting Scholarship = 25%
Hence,
∵ if 25% of boys are getting Scholarship
% of boys won't be getting the scholarship is = (100 - 25)% = 75%.
75% of 5x won't get scholarship,
➠ 75/100 × 5x
➠ ¾ × 5x
➠ 15x/4 .
Thereafter,
Where,
➠ No. of girls are = 6x
➠ % of girls getting Scholarship = 20%
Hence,
∵ if 20% of girls are getting Scholarship
% of girls won't be getting the scholarship is = (100 - 20)% = 80%.
80% of 6x won't be getting the scholarship :
➠ 80/100 × 6x
➠ ⅘ × 6x
➠ 24x/5.
Therefore,
Total no. of students won't be getting the scholarship is :
% of students won't be getting the scholarship :

Let the no. of boys be 5x
and no. of girls be 6x
So,total no. of students is 5x+6x=11x
So,the no. of boys got scholarship =
No. of girls got scholarship=
Total no. of student got scholarship=
So,no of students won't got scholarship =
%of student won't get scholarship =
