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".

Suggest me if this logic is wrong.
Let there are 5 girls and 8 boys.
Then total no students=13
No of girls participated =1
No of boys participated =1.
So, Total participation =2.
Thus, ratio=2/13.

I think you are right Sundar, I have seen this question before where the answer was 2/13.

Rawat and Abhishek examples are correct.
For each different number of boys and girls, we get different answers. So we cannot obtain the required answers without knowing the ratio of boys and girls.
So, from this we can conclude that "Data inadequate".
Note: Previously the answer was displayed ans 2/13 in this page. But after getting the suggestions from various math experts the answer has been updated to "Data inadequate".

All the above are correct. Data is inadequate.

Data is inadequate because 1/5 of does not mean that gals are only 5. Same is in boys also.

Sajan is correct. They dint give the total number of students. So data inadequate.

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?.

Ya Manika, I agree with u. Why we supposing the number?
Question is only about the total numbers.......
Question is only about the total numbers.......

According to my option it should be 13/40, because
1/5+1/8=13/40
1/5+1/8=13/40
