Should it be e?
Bec the equation i am able to form is
X= total questions
75%x= 75%(x-24)+ y%24
Y= the percentage of remaining ques she has to attempt correctly

24 * 0,75 = 18 , so the answers we need to be correct are 18. 24-18=6 , so B

Total questions remaining = 24
Also given she has answered 75% questions so far correctly, let x be total questions that she answered
so 3x/4 will be correct answers so far

Total questions on the exam (answered + not answered) = x + 24

She needs atleast 75% of the total questions to be right

let r be the right answers in the remaing questions

3x/4 + r >= 3/4(x+24)

3x/4 + r >= 3x/4 + 18
r >= 18
She needs to answer 18 correctly so maximum incorrect answers = 6

B is the answer

Here your equation is right, when you try to simplify further, RHS becomes as 75%x, which will further be cancelled. Now we can find y as 75%. Therefore answer will be C
