Question 2 of 5
A school has 15 teachers and 20 teaching assistants. They have 200 students. What is the ratio of faculty to students?
Correct Answer: B
Rationale: To find the ratio of faculty to students, add the number of teachers and teaching assistants (15+20 = 35). Then, divide the total faculty by the number of students (35:200). Simplify the ratio to its simplest form, which is 4:17. This is the correct answer because it represents the relationship between the faculty and students accurately. Incorrect choices: A: 3:20 - Incorrect because it doesn't accurately represent the ratio of faculty to students. C: 3:02 - Incorrect because the ratio must be in terms of whole numbers. D: 7:40 - Incorrect as it doesn't reflect the actual ratio between faculty and students.
Question 3 of 5
In Jim's school, there are 3 girls for every 2 boys. There are 650 students in total. Using this information, how many students are girls?
Correct Answer: A
Rationale: To solve this question, we first need to find the ratio of girls to boys, which is 3:2. Then, we can set up a proportion to determine the number of girls. Since there are 3 girls for every 2 boys, the total ratio is 3+2=5 parts. To find the number of girls, we divide the total number of students by the total parts (650/5=130). Finally, we multiply the number of parts allocated to girls by the ratio of girls in the total parts (130*3=390). Therefore, there are 390 girls in Jim's school. Choice A (260) is incorrect as it does not consider the correct ratio. Choice B (130) is incorrect as it calculates the total parts instead of the number of girls directly. Choice C (65) is incorrect as it only considers one part of the ratio. Choice D (390) is incorrect as it miscalculates the number of boys, not
Question 4 of 5
A quantity increases from 40 to 60. Express this increase as a percentage.
Correct Answer: B
Rationale: To calculate the percentage increase, we subtract the original value from the new value (60 - 40 = 20), then divide this difference by the original value (20 / 40 = 0.5). Finally, multiply this result by 100 to get the percentage increase, which is 50%. Choice B is correct as it accurately represents the percentage increase from 40 to 60. Choices A, C, and D are incorrect because they do not provide the correct percentage increase calculation based on the given values.
