Ok so ratios are poroportion

boys/total=boys/100
total=17+8=25
boys=17
17/25=boys/100
multiply both sides by 100
68=boys


68 boys

So the total number of students equals 8+17 = 25 students
Proportionally:
\frac{17}{25} =  \frac{x}{100}

Thus,
x =  \frac{17*100}{25} = 68 boys out of the 100 students.

The correct answer is option D.

F(G(x)) denotes the composition of the two functions F(x) and G(x). The composition of two functions result in x, if the two functions are inverses of each other. So in this case F(x) and G(x) will be the inverse of each other. So option D is the correct answer.
