Data Inadequate as;

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

The correct option is C).

The answer is "Data inadequate".

Suppose there 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.

The answer cannot be determined until we have the "Ratio of girls to boys".

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.

The answer would be 2/13 cause the question asks for fraction and not the number of students, which will need the ratio of boys and girls.

Take for example since ratio is not given (which is not so necessary after all) I take the number of girls as 5 and boys 8 which gives me 13 students and out of that, 1 boy and 1 girl is participating hence 2/13.

The ratio of girls is 1/5th not the total people for suppose if there r 30 girls then no.of girls participated is 6 and if no.of boys r 24 then 1/8th is 3 nd total participated is 9 and ratio would be 9/54 which is 1/6 so data is inadequate.

According to me, it is 13/40.

Shatarchi said:   4 years ago
A total number of students participated = no of girls + no of boys given.
So, 1/5 + 1/8 = 13/40.

Here the Hidden number is = Total number of Students.

You have to assume a number.

So, we multiply denominators and that should be the total number of students.
(1/5)*40 = 8.
(1/8)*40 = 5,
8+5 = 13
Answer = 13/40.

It is data inadequate as no ratio is given here.

I think it is 2/13.

BOYS = 1/8 AND GIRLS = 1/5.

BOYS + GIRLS=1/8+1/5=13/40.
