My answer is different because,
Let total is x.
x/5+x/8 = 13x/40 taken LCM. But we want fraction.
So, x/13x/40 = 40/13.
My answer is none of these.

@Sneha.
I love the way you added %age of boys and %age of girls to find out the total %age of participation. As per your logic if total boys and total girls participate the fete then total participation will turn to 200% just a minor increase of 100%.

Let us consider that 1/5 girls are participating. That means overall 20% of girls are participating.
Similarly 1/8 boys are participating that means out of 100% only 12.5% boys are participating.
Total 12.5+20 = 32.5% candidate are participating out of 100% student than 32.
5/100 = 13/14 student are participating.
Answer is 13/14.
And I am sure about that.

2/13 is good answer because he talked about two groups and said find total simple add 2 group and there sum is 2/13.

Take total boys as 10 and total girls as 16 for easier calculation. So total strength is 26.
Calculate ratio of boys and girls participated and add them. And find fraction to 26.
You will get 2/13.

There is no saying of the total numbers of students. So the answer is C, there is inadequate information.

According to the fraction point my answer is 13/40 but there is no particular information about students so the C is answer.

Here its given 1/5th of girls and 1/8th of boys.
If we consider (girls, boys) = (5, 8) or (10, 16) so on. We can get our answer as 2/13. But if someone considers (girls, boys) = (15, 16) we get our answer as 5/31.
So by this we cannot blindly decide the strength of boys and girls. Therefore we can opt for Option 'C' i.e., data inadequate'.

What fraction ?
(1/5)+(1/8) = 8+5/5*8 = 13/40.
This is correct answer if only asked to find fraction.
(1/5)+(1/8) = 8+5/5*8 = 13/40.
This is correct answer if only asked to find fraction.
