+103 In an English test 24% of the students did not answered the same question and 10 students failed at that question, the number of the students who answered the question correctly is 1.5 times bigger than the number of students who did not answered the question. how many students were tested?
+129852 Melody, I think we can set this up this way.....
Let x be the total number of students tested
Then, .24x ignored the question, 10 failed to answer it correctly, and 1.5(.24x) answered it correctly. So we have..........
.24x + 10 + 1.5(.24x) = x
.24x + 10 + .36x = x
10 + .60x = x
10 = .40x
x = 25 = the total number of students tested
As a check .24(25) = 6 and 1.5[.24(25)] = 9 and 6 + 10 + 9 = 25

I don't think that I am understanding this question properly.
24% did not answer the question at all
The number who answered it correctly is 1.5 times this which is 36% of the total students.
That makes a total of 60% the rest DID attempt the question but got it wrong.
That means that 40% of all the students is 10 students.
Now if 40% of All = 10 then
All=10*100/40 = 25 student
I thought that there was a problem but it was only in my imagination. This is fine.
