Question 1 of 5

If his distribution cost is $10, what will be his profit?

Correct Answer: B

Rationale: The correct answer is B: $19.60. To calculate profit, we subtract the distribution cost from the total revenue. If the distribution cost is $10, and profit is the remainder, then profit = total revenue - distribution cost. Let's denote total revenue as TR. Therefore, profit = TR - $10. Since the distribution cost is $10, the profit will be TR - $10. To find TR, we add the distribution cost to the profit: TR = profit + $10. If we substitute $10 for the distribution cost and $19.60 for profit, we get TR = $19.60 + $10 = $29.60. This means that the correct answer for the profit will be $19.60. Summary: A: $10.40 - Incorrect. This choice is lower than the distribution cost, so it cannot be the profit. C: $14.90 - Incorrect. This choice is also lower than the distribution cost, ruling

Question 2 of 5

How many more yellow balls must be added to the basket to make the yellow balls constitute 65% of the total number of balls?

Correct Answer: B

Rationale: To make yellow balls 65% of total, they need to be 65 out of every 100 balls. Let the number of yellow balls be Y. Total balls = Y + X. So, Y/(Y+X) = 65/100. Solving, Y = 13X. To make yellow balls 65%, the ratio of yellow to total should be 13:20. So, 13/(13+20) = 13/33 = 39.4%, which means 60.6% are non-yellow balls. To increase yellow balls to 65%, we need to make non-yellow balls 35%. Therefore, 35% of total balls should be non-yellow. This means 35% of total balls should be non-yellow. Hence, the correct answer is 50 (option B). Other choices are incorrect as they do not align with the logic of maintaining the 65% yellow ball ratio.

Question 3 of 5

What percent of 36 is 9?

Correct Answer: D

Rationale: To find what percent of 36 is 9, we divide 9 by 36: 9/36 = 0.25. To convert this decimal to a percentage, we multiply by 100: 0.25 x 100 = 25%. So, the correct answer is D (10%). Choice A (25%), B (20%), and C (15%) are incorrect as they do not correctly represent the relationship between 9 and 36.

Question 4 of 5

How many pints are in 56 ounces?

Correct Answer: A

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16. 56 ÷ 16 = 3.5 pints. So, the correct answer is A: 3.5 pints. Choices B, C, and D are incorrect because they do not accurately represent the conversion of 56 ounces to pints based on the conversion factor of 1 pint = 16 ounces.

Question 5 of 5

The physician ordered 16 mg of Ibuprofen per kg of body weight; on hand are 80 mg tablets. The child weighs 15 kg. How many tablets will you give?

Correct Answer: B

Rationale: To calculate the number of tablets needed: 1. Determine the total dosage needed: 16 mg/kg x 15 kg = 240 mg. 2. Divide the total dosage by the dosage per tablet: 240 mg ÷ 80 mg = 3 tablets. 3. The correct answer is B (2 tablets) as it is the nearest whole number to the calculated 3 tablets. Choice A is incorrect because it is less than the calculated amount. Choice C is incorrect as it is less than the required dosage. Choice D is incorrect as it is a non-integer value.
