But what if you put "15 percent" between "much/many" and the noun?

Does it still depend on the noun?

According to MGMAT, you have to write "as much as 15 percent of the population". I got the question right, but it was because I was thinking that I had to write "as much as" because of the "15 percent", not because of the uncountable noun (the population).

So does that mean that I have to write "as many as 15 percent of my girlfriends" for instance, since girlfriends are countable?

"As much as 15 percent of my girlfriends" sounds better to me.

population is a quantity; ofcourse, in its a number, but population is only one thing. what I mean is you don't have populations as in the case of girl frens. you can count girl frens but not population. You can count the number of people that constitutes Population ( but not population itself). Therefore, you can only refer to a part of population by using "as much as 15%".

Do I make sense to you ?

The real question is indeed: do you write "As much as 15 percent of my girlfriends" or "as many as 15 percent of my girlfriends"?

I also believe that because of the "15 percent", the girlfriends become uncountable because they become an amount.

By the way, it was question 8 in the Manhattan GMAT CAT test #2:

"Poor weather in early 14th-century Europe created meager harvests, causing the result of mass starvation in some areas and the elimination of as many as 15 percent of the population."
