Given: In the year 2001, a company's sales increased by x percent from the year 2000. In 2002, sales decreases x percent from the year 2001. If the sales in 2002 is 9 percent less than that in 2000,
Asked: what is x?
If sales in 2000 = 1
Sales in 2002 = (1+x)(1-x) = 1+x-x-x^2 = 1-x^2
x^2 = .09
x=.3 = 30%
IMO B

Let’s say that
—sales in 2000 is 100$;
—(increased by x percent) sales in 2001 is (100+x);
—(decreased by x percent) sales in 2002 is (100+x)—(100+x)*(x/100)=(100+x)*(1–x/100)=(100^2-x^2)/100
It says that sales in 2002 is 9 percent less than that in 2000
—> 100–9=91
(100^2–x^2)/100=91
x^2=100^2–91*100=900
x=30
The answer choice is B
