Kudos for a correct solution. 60 percent of those who receive a questionnaire by mail will respond Rewrite as: 60 percent of receivers = respondersWe want 300 responders, so rewrite as: 60 percent of receivers = 30060% of what = 300? Option #1) Check answer choicesA) 400 60% of 400 = 240 (nope, we want 300) . . . D) 500 60% of 500 = 300...works!! Or option #2) algebra60% of x = 3000.6x = 300 x = 300/0.6 = 500 = DOr...60% of x = 3000.6x = 300 (3/5)x = 300 x = (5/3)300 = 500 = D Related ResourcesCheers, Brent

Kudos for a correct solution. 60%*x=300 ===> 60/100 * x= 300 300*100 / 60 = x x=500 D

(A) 400 (B) 420 (C) 480 (D) 500 (E) 600 If we let x = the number of questionnaires that should be mailed, then x must satisfy 0.6x = 300. Then, x = 300/0.6 = 500. Answer: D

One of the most overlooked ways to solve such questions is "Guess and Check". If we look at this question, we can see that the easiest option to attack is (D) 500:
500 is half of 1000. So 60% of 1000 = 600, and hence 600% of 500 (which is half of 1000) will be 300 > our answer (D).
