In the game of Dubblefud, red chips, blue chips and green chips are each worth 2, 4 and 5 points respectively. In a certain selection of chips, the product of the point values of the chips is 16,000. If the number of blue chips in this selection doubles the number of green chips, how many red chips are in the selection?  Pick
A) 1	B) 2	C) 3	D) 4	E) 5
this is equivalent to :-   2x * 4y * 5z = 16000   y/2= z (given)   2x * 4y * 5y/2= 16000   2x * y^2 = 16000/10   2x * y^2 = 1600   now from options given we will figure out which number will divide 800 and gives us a perfect square :-   which gives us x=2 as   2* 2* y^2 =1600   y^2 = 400   y =20   Number of red chips = 2 hence 2
