Correct Answer: D

Rationale: To calculate the percentage difference, we need to find the percentage increase from City X to City Y. Let's assume City X has 100 staff members, with 40 females, making 40% female. In City Y, there are 120 staff members, with 60 females, making 50% female. The percentage difference is (50% - 40%) / 40% = 0.25 or 25%. Therefore, there are 25% more female staff in City Y compared to City X, which is equivalent to 20% of the female staff in City X. So, the correct answer is D (20%). Choice A (5%), B (10%), and C (15%) are incorrect as they do not accurately reflect the 20% increase in female staff members between the two cities.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Kyle wants to donate one-fifth of his $950 savings to 8 charities. 2. One-fifth of $950 is $190 ($950 / 5 = $190). 3. If he donates $30 to each charity, $30 x 8 charities = $240. 4. His estimate of donating $240 is more than $190 (one-fifth of $950). 5. Hence, the estimate is not reasonable as $240 exceeds one-fifth of his total savings.

Correct Answer: C

Rationale: To find the total percent deducted, you add the percentages taken for taxes and insurance. 35% + 4% = 39%. Therefore, the correct answer is C (39%). Choice A (20%) is too low, as it only considers the tax deduction. Choice B (31%) and Choice D (42%) are incorrect because they don't account for both deductions.

Correct Answer: B

Rationale: To calculate the total height of the stacked bookcases, you add the heights of the two bookcases together. The larger bookcase is 14 inches tall, and the smaller one is 8 inches tall. Adding them gives us 14 + 8 = 22 inches. Therefore, the correct answer is B: 22 inches tall. Choice A: 12 inches tall - Incorrect because it doesn't account for the height of the larger bookcase. Choice C: 35 inches tall - Incorrect because it adds the heights of the two bookcases incorrectly. Choice D: 41 inches tall - Incorrect because it adds the heights of the two bookcases incorrectly.

Correct Answer: C

Rationale: To find the cars with both a man and a woman, we can use the formula: Total = Man + Woman - Both + Neither. Given Man = 20, Woman = 13, Total = 25, and Neither = 0 (since each car has at least one person), we can plug in the values: 25 = 20 + 13 - Both + 0. Solving for Both, we get Both = 8. Therefore, the correct answer is C (8 cars with both a man and a woman). Summary: A: Incorrect. There are more cars with a man. B: Incorrect. This number is too high considering the given information. D: Incorrect. This is the total number of cars, not the number with both a man and a woman.
