1. In a certain population, there are times as many people aged 21 or under as there are people over 21. The ratio of those 21 or under to the total population is :
- A. 1 to 2
- B. 1 to 2
- C. 1 to 2
- D. 1 to 2
Answer: Option E
Explanation:
Let the number of people over 21 years be x. Given that the number of people aged 21 or under = 3x So total population = 4x Required ratio = 3x : 4x = 3:4 So the answer choice is (e) 3 to 4.
