If Mr. Parker owns 150 shares of stock in Stark Industries and receives $180.00 per year in dividends, how much does Mr. Rogers receive for an annual dividend if he owns 400 shares?

  • A. $480
  • B. $500
  • C. $450
  • D. $72,000
Correct Answer: A

Rationale: To find out how much Mr. Rogers receives for an annual dividend with 400 shares, we can set up a proportion: 400 shares is to X dollars as 150 shares is to $180. This gives us 400 * $180 / 150 = $480 in annual dividends. Therefore, the correct answer is A. Choice B, $500, is incorrect because it does not consider the proportionality of shares to dividend amount. Choice C, $450, is incorrect as it does not reflect the correct calculation based on the given information. Choice D, $72,000, is significantly higher and incorrect as it does not align with the proportionality of shares and dividends.

Which number is the highest among 0.077, 0.777, 0.08, and 0.87?

  • A. 0.077
  • B. 0.777
  • C. 0.08
  • D. 0.87
Correct Answer: D

Rationale: To determine the highest number among 0.077, 0.777, 0.08, and 0.87, we compare the numbers. 0.87 is greater than 0.777, 0.08, and 0.077, making it the highest number. Choice A (0.077), Choice B (0.777), and Choice C (0.08) are lower numbers compared to 0.87, so they are incorrect.

A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

  • A. 300mg
  • B. 600mg
  • C. 750mg
  • D. 900mg
Correct Answer: D

Rationale: Rationale:
- The patient receives 150mg of medication every 4 hours.
- To calculate how many milligrams the patient will receive in 24 hours, we need to determine how many times the medication is administered in 24 hours.
- Since the medication is administered every 4 hours, there are 24 hours in a day, so the medication will be administered 24 / 4 = 6 times in 24 hours.
- Therefore, the total amount of medication the patient will receive in 24 hours is 150mg x 6 = 900mg.

A runner leaves at 7:45 for a morning run at an average speed of 6 mph and returns at 10:00. How many miles did he run?

  • A. 11.5 miles
  • B. 14.5 miles
  • C. 12 miles
  • D. 13.5 miles
Correct Answer: D

Rationale: The runner left at 7:45 and returned at 10:00, which means he ran for 2 hours and 15 minutes (10:00 - 7:45). At an average speed of 6 mph, in 2.25 hours, he would have covered 6 mph * 2.25 hours = 13.5 miles. Therefore, the correct answer is 13.5 miles. Choices A, B, and C are incorrect because they incorrectly calculate the distance based on the time and speed provided in the question.

What is the greatest common factor (GCF) of 12 and 18?

  • A. 2
  • B. 3
  • C. 6
  • D. 9
Correct Answer: C

Rationale: The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 12 and 18, we factorize each number: 12 = 2 x 2 x 3 and 18 = 2 x 3 x 3. The common factors are 2 and 3. The GCF is the product of these common factors, which is 6. Therefore, 6 is the greatest common factor of 12 and 18. Choice A (2) and Choice B (3) are factors of both numbers but not the greatest common factor. Choice D (9) is not a factor of both 12 and 18, making it incorrect.

If two workers can finish building a play set in 18 hours, how long will it take 4 workers to build 3 play sets?

  • A. 27 hours
  • B. 36 hours
  • C. 24 hours
  • D. 54 hours
Correct Answer: A

Rationale: If 2 workers can complete building one play set in 18 hours, it means one worker would take 36 hours to complete the same task. When the number of workers is doubled to 4, the time is halved, so 4 workers would take 18 hours to build one play set. To build 3 play sets, the total time needed would be 3 times the time for one play set, which equals 54 hours. Therefore, 4 workers can build 3 play sets in 27 hours, making choice A the correct answer. Choices B, C, and D are incorrect because they do not account for the correct relationship between the number of workers and the time required to complete the task.
