Bill owns a large collection of fishing lures consisting of tiny, small, medium and large lures that weight 1,3, w and 5 grams each, respectively. The medium lures weigh more than the small lures but less than large lures. If the product of the lure weights that Bill sold to his friends is 216,000 grams, how many medium lures did he sell?
A. 6 B. 5 C. 4 D. 3 E. 2

I don't know the answer. I cannot get to any answer. It is from Kaplan Problem set 7. If anybody know how to solve, please help otherwise I am assuming sth is missing.

all its saying is that 3<w<5 possibly w=4, if only integer values permitted.

now 216000 = 5*5*5*8*27*8 = 4^4*3^3*5^3

excluding multiples of 3 and 5 it is 4 , 4's so C

should be 4^3

216 * 1000 2 2 2 3 3 3 2 5 2 5 2 5 2^6 4^3

so it's D) 3

I agree there are 3 4's.

Boiled 216000 down I got: 5x5x5 3x3x3 AND 2x2x2x2x2x2 or 4x4x4

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
