A certain factory produces buttons and buckles at a uniform weight. If the total weight of 2 buttons and 2 buckles is one third of 11 buckles and 3 buttons, then the weight of 3 buttons and 2 buckles is how many times that of 5 buckles and 6 buttons?
Select
A) 7/15 B) 4/9. C) 6/11 D) 5/9 E) 8/15
2 buttons + 2 buckles = 1/3(11 buckles + 3buttons)   6 buttons + 6 buckles = 11 buckles + 3buttons   3buttons = buckles   Weight of 3buttons and buckles = 5buckles + 2buckles = 7buckles   Weight of 6buttons and 5buckles = 10buckles + 5buckles = 15buckles   (3buttons and 2buckles) = x * (6buttons and 5buckles)   7 = x*15   x = 7/15   7/15nswer: 7/15
