If a person reads two chapters a day, with each chapter having 6 pages, and there are 798 pages in total, how many days will it take them to finish reading?

  • A. 133
  • B. 399
  • C. 66 1/2
  • D. 75 1/2
Correct Answer: C

Rationale: To determine the number of days it will take to finish reading 798 pages, divide the total number of pages by the number of pages read in a day. Since the person reads 2 chapters per day, equivalent to 12 pages per day (2 chapters * 6 pages per chapter), it will take them 798 / 12 = 66.5 days, which is the same as 66 1/2 days. Therefore, the correct answer is 66 1/2, representing the number of days needed to complete reading all 798 pages if two chapters of 6 pages each are read daily.

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 of the same company?

  • A. 480
  • B. 500
  • C. 450
  • D. 72000
Correct Answer: A

Rationale: To determine how much Mr. Rogers receives annually in dividends for his 400 shares, you can set up a proportion based on the number of shares. The ratio of dividends to shares for Mr. Parker is $180/150 = $1.20 per share. By applying this ratio to Mr. Rogers with 400 shares, the calculation would be $1.20 x 400 = $480. Therefore, the correct answer is A, $480.

Subtract 3/5 - 2/7 =

  • A. 1/2
  • B. 3/35
  • C. -1/2
  • D. 11/35
Correct Answer: D

Rationale: To subtract fractions, you need a common denominator. In this case, the common denominator of 5 and 7 is 35. Rewrite the fractions with the common denominator: 3/5 = 21/35 and 2/7 = 10/35. Subtract: 21/35 - 10/35 = 11/35. Therefore, the correct answer is D, 11/35. Remember, when subtracting fractions, always ensure to find a common denominator to perform the operation accurately.

Find x: 40:5 = 60:x

  • A. 7.5
  • B. 1.5
  • C. 12
  • D. 15
Correct Answer: A

Rationale: To find the value of x in the proportion 40:5 = 60:x, you can cross multiply. This gives you 40 * x = 5 * 60, which simplifies to 40x = 300. To solve for x, divide both sides by 40, resulting in x = 300 / 40 = 7.5. Therefore, the correct answer is A, 7.5. The other choices can be eliminated by following the correct mathematical procedure. Choice B, 1.5, is incorrect as it does not satisfy the proportion equation. Choices C and D, 12 and 15, respectively, are also incorrect as they are not the solutions obtained by solving the proportion equation.

Multiply: (88)(7.08) =

  • A. 862.5
  • B. 88.04
  • C. 64.252
  • D. 623.04
Correct Answer: D

Rationale: To find the product of (88)(7.08), multiply the two numbers together: 88 x 7.08 = 623.04. Therefore, the correct answer is 623.04. When multiplying whole numbers and decimals, it is essential to follow the rules of multiplication and perform the calculations accurately to obtain the correct result. In this case, multiplying 88 by 7.08 gives us 623.04. It is crucial to pay attention to decimal placement and ensure each digit is correctly multiplied to reach the accurate product.
