Say for Example total student is X. We have to assume as this number is not given;
Now, Boys participated = X/8,
Girls Participated = X/5,
Total Number of student participated = X/8 +X/5 = 13X/40,
Here if you dont know X you wil never be able to know value fo total number of student participated.
Thus data inadequate.

Ans is "Data inadequate".
Suppose ther are 18 students (10 girls, 8 boys).
1/5 of 10=2 (girls).
1/8 of 8=1 (boy).
Total participation=2+1=3.
Total students=10+8=18.
Answer = 3/18 = 1/6.
Answer cannot be determined until we have the "Ratio of girls to boys".

According to my opinion it should be 13/40, because
1/5+1/8 = 13/40,
because the question only ask about the What fraction of the total number of students took part in the fete?.
1/5+1/8 = 13/40,
because the question only ask about the What fraction of the total number of students took part in the fete?.

According to the question, we are not informed regarding the total no of students.
So, let total no of students = x.
No of girls participated = x/5
No of boys participated = x/6
So, total no of students participated = 13x/40, then a fraction of the original number of students obtained = 13x/40 * 1/x = 13/40.
So, let total no of students = x.
No of girls participated = x/5
No of boys participated = x/6
So, total no of students participated = 13x/40, then a fraction of the original number of students obtained = 13x/40 * 1/x = 13/40.

I think the answer is 13/40 because according to my options:
1/5 + 1/8 = 13/40.
Then, how the answer should be Data not adequate?
1/5 + 1/8 = 13/40.
Then, how the answer should be Data not adequate?

The correct answer is 2/12 because the total no of girls = 5, participated girls = 1 and total no of boys = 8 participated boys = 1.
So total no of students = 13 particepated students= 2.
Then by the fraction it is = 2/13.
So total no of students = 13 particepated students= 2.
Then by the fraction it is = 2/13.

Yeah, data inadequate. According to me. There should be a ratio of No of girls and No of boys.

x=1/5:y=1/8, x+y=1/5+1/8=5+8/40=13/40 is answer.

Can anyone tell me how could we know the fraction by having ratio of girls to ratio of boys?
