Correct answer: A. 50
- A. 50
- B. 52
- C. 58
- D. 60Educational Resources
Explanation
If the number is x, exceeding 16% of it by 42 means x - 0.16x = 42. Hence 0.84x = 42 and x = 42 / 0.84 = 50. The common mistake is option b, 52, from adding 16% of 42 to 42 instead of forming the stated equation.
