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

What is 2/3 of 60 + 1/5 of 75?

Correct Answer: B

Rationale: To find 2/3 of 60, multiply 60 by 2/3, which gives 40. Next, find 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Adding 40 and 15 gives us 55. Therefore, the correct answer is B (55). Choice A (45) is incorrect as it only considers 2/3 of 60 without adding 1/5 of 75. Choices C (15) and D (50) also do not account for both parts of the equation.

Question 3 of 5

Express the number 1906 in Roman numerals.

Correct Answer: B

Rationale: The correct answer is B: MCMVI. Here's the rationale: 1. M represents 1000, CM represents 900, and VI represents 6. 2. Combining these symbols, MCMVI represents 1000 (M) + 900 (CM) + 6 (VI) = 1906. 3. Option A (MCMIV) is incorrect as IV represents 4, not 6. 4. Option C (MDCCCCVI) is incorrect as it uses the subtractive notation excessively (900 + 100 + 100 + 100 + 100 + 5 + 1). 5. Option D (MCMVII) is incorrect as VII represents 7, not 6.

Question 4 of 5

Sally was able to eat 5/8 of her lunch. John ate 75% of his lunch. Who ate more?

Correct Answer: A

Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.

Question 5 of 5

How much paint do you need to paint the interior walls and floor of a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m? (Assume one can of paint covers 10 sq m)

Correct Answer: C

Rationale: To calculate the total area to paint, we need to find the surface area of the walls and the floor separately. The surface area of the walls is 2*(8+5)*2 = 36 sq m. The floor area is 8*5 = 40 sq m. Adding these together gives 36 + 40 = 76 sq m. Since one can of paint covers 10 sq m, we need 76/10 = 7.6 cans of paint. Rounding up to the nearest whole number, we need 8 cans of paint, which is equivalent to 88 sq m. Therefore, the correct answer is C (88 sq m). Choice A (56 sq m) is incorrect as it does not consider the surface area of the floor. Choice B (72 sq m) is incorrect as it miscalculates the total area to paint. Choice D (104 sq m) is incorrect as it overestimates the amount of paint needed.
