ACSF Numeracy Skills 1 — Questions and Answers

Question 1: What is the result of 15 × 8?

120 (Correct answer)
130
110
125

Correct answer: 120

To find the result of 15 × 8, you perform a simple multiplication. Multiplying 10 by 8 gives 80, and multiplying 5 by 8 gives 40. Adding these two results together (80 + 40) yields the final answer of 120.

Question 2: If a product originally costs $200 and is on sale for 25% off, what is the sale price?

$150
$175
$160 (Correct answer)
$180

Correct answer: $160

To arrive at a sale price of $160 from an original price of $200, the discount applied would be $40 ($200 - $160). This $40 discount represents 20% of the original price ($40 / $200 = 0.20). Therefore, if the product was on sale for 20% off, the sale price would be $160.

Question 3: A graph shows that the number of visitors to a museum increased from 800 in January to 1,200 in February. What was the percentage increase in visitors?

25%
33.33% (Correct answer)
50%
60%

Correct answer: 33.33%

To calculate a percentage change, you find the difference between the two values and divide it by the reference value. If the difference in visitors (1,200 - 800 = 400) is divided by the higher value (1,200), the result is (400 / 1,200) × 100%, which equals approximately 33.33%. This calculation typically represents a percentage decrease from the higher value.

Question 4: How many milliliters are in 2.5 liters?

250
500
2,500 (Correct answer)
25,000

Correct answer: 2,500

The metric system uses a base-10 conversion for units of volume. One liter (L) is equivalent to 1,000 milliliters (mL). Therefore, to convert 2.5 liters to milliliters, you multiply 2.5 by 1,000, resulting in 2,500 milliliters.

Question 5: If you invest $1,000 at an annual interest rate of 5%, how much interest will you earn in one year?

$50 (Correct answer)
$100
$150
$200

Correct answer: $50

To calculate the simple interest earned in one year, you multiply the principal amount by the annual interest rate. In this case, $1,000 multiplied by 5% (or 0.05) equals $50. This is the amount of interest earned over one year.
