If w is 40 percent less than t, t 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? Choose the correct choice
A) 4%  B) 18%  C) 36%  D) 40%  E) 50%
GIven w= 0.6t, t=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.
