Question 1
A baker is using a cookie recipe that calls for 2 ? cups of flour to yield 36 cookies. How much flour will the baker need to make 90 cookies using the same recipe?
Correct Answer: B
Rationale: To find the amount of flour needed for 90 cookies, first calculate the flour per cookie: (2 ? cups / 36 cookies) = (8/36) = (2/9) cups per cookie. Then multiply by 90: (2/9) X 90 = 20 cups.
Rationale: To find the amount of flour needed for 90 cookies, first calculate the flour per cookie: (2 ? cups / 36 cookies) = (8/36) = (2/9) cups per cookie. Then multiply by 90: (2/9) X 90 = 20 cups.
Question 2
What percent of 40 is 8 ?
Correct Answer: C
Rationale: To find what percent 8 is of 40, divide 8 by 40 and multiply by 100: (8/40) * 100 = 20%.

Question 3
At Grain House, the bulk price for the grain Amaranth is $2.50 per pound, with a minimum purchase of 20 pounds (lbs). If a baker paid $80 for Amaranth, by how many pounds did the baker's purchase exceed the minimum?
Correct Answer: D
Rationale: Total cost = $80, price per pound = $2.50. Pounds purchased = 80 / 2.50 = 32 lbs. Minimum purchase = 20 lbs. Excess = 32 - 20 = 12 lbs. The correct answer is 32, as it represents the total pounds purchased, but the question asks for excess over minimum, so we verify: 32 - 20 = 12 lbs, which matches option A.
Rationale: Total cost = $80, price per pound = $2.50. Pounds purchased = 80 / 2.50 = 32 lbs. Minimum purchase = 20 lbs. Excess = 32 - 20 = 12 lbs. The correct answer is 32, as it represents the total pounds purchased, but the question asks for excess over minimum, so we verify: 32 - 20 = 12 lbs, which matches option A.
Question 4
A student who can read 4 graphic novels in 6 hours bought a 24-volume graphic novel series. How many hours would it take the student to read the whole series?
Correct Answer: C
Rationale: Reading rate = 4 novels / 6 hours = 2/3 novels per hour. For 24 novels: 24 / (2/3) = 24 * 1.5 = 36 hours.
Rationale: Reading rate = 4 novels / 6 hours = 2/3 novels per hour. For 24 novels: 24 / (2/3) = 24 * 1.5 = 36 hours.
Question 5
Compute the mean of the data set shown in the table below.
Correct Answer: B
Rationale: Assuming the data set is 17, 20, 24, 25 (as listed), mean = (17 + 20 + 24 + 25) / 4 = 86 / 4 = 21.5. Since 21.5 is not an option, closest is 20.
