Question: 211
5. If 20% of a number is 90, then 60% of that same number is
- A. 60
- B. 180
- C. 270
- D. 450
Correct Answer: C
Explanation:
The answer is C
First, to find the number, set up a proportion, cross multiply, and divide by 20: 
, 20x = 9,000, and x = 450. Then find the answer by following the same procedure: 
, 100x = 27,000, and x = 270.
You can use logic. 60% of a number is three times greater than 20% of the number. Thus, simply multiply 90 by 3.
