Answer:
40%.
Step-by-step explanation:
Total number of beads = 34 + 51 = 85.
The fraction which are blue = 34/85.
As a percentage this is (34*100) / 85
= 40%.
Now, let's say there are "b" boys and "g" gals... ok... well, we know there are 116 more boys than gals..... so, if there are "g" gals then there must be "g + 116" boys.

what's the total class? well is g + b or g + ( g + 116).
I'm gonna say A. It makes the most sense to me.
