I believe the answer is A. 200 - 80 (households that use neither) = 120. 120 - 60 (used only A) = 60. 60/4 (1 for dual users and 3 for B only) = 15. - Soup in a TARDIS

I agree with Soup. - Jimminy

yes, it's the answer. but how did you know " for every household that used both brands of soap, 3 used only Brand B soap" is "1 for dual users and 3 for B only"? did households have four people? - dominic

it's the problem of the question that I misunderstand the sentence, I think. - dominic

You start with a set of 200 people who use soap. 80 don't use either brand. 60 use Brand A. The remaining group of 60 people, either uses Brand B or both Brands A & B. Of the remaining people the ratio is 3(Brand B exclusively) to 1(Brands A&B). So those that use brand B is 3/4 and both is 1/4. - Jimminy

200 = N + A + B + Z; N = 80; A = 60; B = 3Z (where N = neither, A = brand A, B = brand B, Z = both) - Jim Norris

Bump. - Jessie

Is there a special area of concentration you're interested in, Dominic? - Anne Bouey

@Anika, thank you very much. I found some many infomation online about MBA, but I didn't know how to choose or classify. It's not easy for me to apply the best MBA. That's why I may need some infomation here. Thank you again. - dominic

@Anne, yes, I decided to focus on the special area related to finance and economics. - dominic

I think I know one person in that field, most people I know went in for global leadership. <--I should look that up to make sure. I'll see what the econ woman says (I know she has a BA in economics, not sure why she's at AU). I think she's still there. - Anika

Green Island used to be famous for its prison, like "Taiwan's Alcatraz." Before it was used mostly for Taiwan's political prisoners, but now the prison is a museum. - dominic

However, I am far away from past time...that's why I can come out of the prison. - dominic

Haha I'm happy you could escape the prison :P - Jessie

That is very cool! - Rachel Lea Fox

If you're able to see the genealogy program "Faces of America", they went to China to do some of Yo-Yo Ma's genealogy and I believe his family used the same naming convention. I can't remember how the character was chosen, I just remember that it was chosen far in advance and dictated to each generation. http://www.pbs.org/wnet... - Spidra Webster

It really does save more space. The amount saved by a single bike is minimal but the amount saved by a full "trees" worth built into a circle (I'm thinking footprint wise) is significant. Vertical hangs lose major points from me for their sheer unwieldiness however. We have them in my building (in a row formation, not a tree) and its just a huge pain in the butt getting bikes on and off the rack. - Soup in a TARDIS

Because they are vertical, not horizontal there should be some space saving but it probably is much more secure. - Brian Sullivan
