Two numbers are respectively 20% and 25% more than a third number. The percentage that is first of the second is_________?
Correct answer: C. 96%
- A. 80%
- B. 85%
- C. 96%
- D. 125%
Explanation
Let the third number be N. The first number is 120% of N = 1.20N, and the second is 125% of N = 1.25N. Therefore, the first as a percentage of the second is (1.20N / 1.25N) x 100% = 96%. The likely mistake is calculating the first number as 120% of the second instead of comparing both with the common third number.
