GMAT Prep Test

by awilhelm » Tue Dec 16, 2008 8:23 pm
A manufacturer produced x percent more video cameras in 1994 than in 1993 and y percent more video cameras in 10995 than in 1994. If the manufacturer produced 1,000 video cameras in 1993, how many did he produce in 1995?

1) xy = 20
2) x + y + xy/100 = 9.2

Any ideas?

Parallel chase (I call him the PC) has provided a good explanation here!
