According to me,
Let a=1/5 b=1/8
LCM =40.
a=1/5*8/8=8/40.
b=1/8*5/5=5/40.
= 8/40+5/40 = 13/40.
Let a=1/5 b=1/8
LCM =40.
a=1/5*8/8=8/40.
b=1/8*5/5=5/40.
= 8/40+5/40 = 13/40.

A total number of students participated = no of girls + no of boys given.
So, 1/5 + 1/8 = 13/40.
So, 1/5 + 1/8 = 13/40.

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

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

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

Boys participation = 1/8.
Girls participation = 1/5.
According to 1/8+1/5.
13/40 answer.
Girls participation = 1/5.
According to 1/8+1/5.
13/40 answer.

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

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

Data Inadequate as;
1/5x+1/8y = x+y only one linear equation in two variables.
1/5x+1/8y = x+y only one linear equation in two variables.

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