Let's assume that the number of boys is X, then the number of girls is 2X.
At the meeting, let the number of boys be b and girls be g. Then, (g/2X)*100= 2*(b/X)*100, for which g=4b
Then, the total number of students at the meeting is g+b = 4b+b = 5b
Thus, as number of boys is b, %of boys is (b/5b)*100 = 20
Hence, Answer A!

We can let the percentage of girls attending = 100 and the percentage of boys = 50. Thus, there were 20 girls and 5 boys, so the percentage of boys was 5/25 = 1/5 = 20%. Answer: A

I think what is confusing here is the omission of all students needing to attend.
Boys = 50 Girls = 100
If 80% of Girls show up and 40% of boys, we have:
20 boys and 80 girls, i.e., 25% ...
Confusing question IMHO
