If w is 40 percent less than x, x is 40 percent less than y, and z is 46 percent less than y, then z is greater than w by what percent of w?
Options: A) 4% B) 18% C) 36% D) 40% E) 50%
Given   w= 0.6x, x=0.6y, z=0.54y,   substituting, w=2/3 Z----&gt; z= 1.5w   and thus z is 50% greater than w.   50% is the correct answer.
