Hi All,
While this question is wordy, it can be solved by taking the proper notes and TESTing VALUES.
We're told that X bicycles were sold in each of the years 1990 and 1993.
IF.... X = 100
100 bicycles sold in 1990
100 bicycles sold in 1993
Next, we're told that the producers had a 42% share of the market in 1990 and a 33% share of the market in 1993....
1990 share = 42% of 100 = 42 bicycles
1993 share = 33% of 100 = 33 bicycles
We're asked for the DECREASE in the NUMBER of bicycles sold by those producers from 1990 to 1993. That number is 42 - 33 = 9, so we're looking for an answer that equals 9 when we place X = 100 into the answer choices. There's only one answer that matches...

I came up with the same approach when I saw this question for the first time, however, I still doubted my answer.
What I don't get is why it only works when plugging in 100.
Because if we say the market consists of 1000 bicycles then we would have a much larger %-decrease.
