A certain movie depicted product A in 21 scenes, product B in 7 scenes

(1)

21x + 7x = $560,000

=> x = 560000/28 = 20000

So D paid -> 200000 * 3 = 60000

Sufficient


(2)

7x - 4x = 60000

=> x = 20000


So D paid -> 200000 * 3 = 60000
Sufficient.

Answer- D

let the proportionality constant be k such that the amount paid are in the ratio 21k:7k:4k:3k

we need to find k for this.

a 21k + 7k = 60 * 10^3 k's value can be found. Hence 3k will be D's amount.
b 7k- 60000 = 4k k's value can be found. Hence 3k will be D's amount.

Thus D.

Hi All,

GMAT questions are always carefully worded, so you really have to pay attention to the details (and take the necessary notes) so that you don't miss anything.

In this question, we're told that EACH manufacturer paid X dollars PER SCENE. That is a "fixed" rate that is the same for everyone.

So....
1 scene = X dollars
2 scenes = 2X dollars
3 scenes = 3X dollars
Etc.

We're also told the number of scenes that each manufacturer advertised in (21 for A, 7 for B, 4 for C and 3 for D). The question asks how much was paid by D. From here, the real question is "what is X?" If we know the price per scene, then we can figure out what D paid (3X = the answer). When dealing with the 2 Facts, we're really just doing simple algebra.

Fact 1: A and B paid a total of $560,000

A and B had a combined total of 28 scenes, so...

28X = 560,000
X = 20,000
Fact 1 is SUFFICIENT

Fact 2: B piad $60,000 more than C

7X = 4X + 60,000
3X = 60,000
X = 20,000
Fact 2 is SUFFICIENT

Final Answer:

GMAT assassins aren't born, they're made,
Rich

1) 21x + 7x =560,000
x = 20,000.
So, for D, (3*20,000)= 60,000. Suf

2)7x -4x =60,000. Same as 1. Suf
So, D is the answer.
