Fishing lures

by aagar2003 » Sat Jul 16, 2011 11:44 am
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
