Re: A survey was conducted on 208 companies that make use of at least one [#permalink]

Please: see our math handout or math book for more on overlapping sets

Usually on the GRe they are fairly simple

Use the formula

X+Y-Both (the intersection where a company use both systems) + Neither (outside of the intersection)= Total

X+Y-B+0=208 we are looking for both as variable

120+90-B+0=208

B=2

So we need to find X now

120-2=118

A>B

I hope this helps


Thanks, I was making the box set, my bad :(
