GMAT Prep2?? (Movies)

by dferm » Wed May 14, 2008 8:48 pm
A certain movie depicted product A in 21 scenes, product B in 7 scenes, product C in 4 scenes, and product D in 3 scenes. The four product manufacturers paid amounts proportional to the number of scenes in which their product was depicted in the movie. If each manufacturer paid x dollars per scene, how much did the manufacturer of product D pay for this advertising?

(1) The manufacturers of Product A and B together paid a total of $560,000 for this advertising

(2) The manufacturer of Product B paid $60,000 more for this advertising than the manufacturer of product C paid

Please Help...

Thanks..

Now that you said D is ans i can say it's simple :-)


From the q itself we can say every scene carries the same price i.e. $x

From 1: 21x+7x=560,000
x can be known. Then for D 3x.

From 2: 7x-4x=60,000
x can be calculated and so is for D i.e 3x.
