Question 1
What is the simple interest earned on $100 at 5% for 2 years?
Correct Answer:
$10
Explanation:
Interest from simple interest is found by multiplying the principal by the annual rate and the time: I = P × r × t. Here P is 100 dollars, r is 0.05 (5%), and t is 2 years. So I = 100 × 0.05 × 2 = 10 dollars. At a 5% rate, you earn 5 dollars each year on 100, for two years totaling 10. Since this is simple interest, there’s no additional interest on the interest.
Question 2
If a circle has radius 7 cm, what is its circumference? Use pi ≈ 3.14.
Correct Answer:
43.96 cm
Explanation:
This question uses the relationship between a circle’s radius and its circumference: C = 2πr. With a radius of 7 cm and π ≈ 3.14, the circumference is C ≈ 2 × 3.14 × 7 = 6.28 × 7 = 43.96 cm. You can also use the diameter (d = 14 cm) with C = πd, giving the same result: 3.14 × 14 = 43.96 cm.
Question 3
How many cups are in 1 pint?
Correct Answer:
2 cups
Explanation:
Two cups. In US customary measurements, a pint is 16 fluid ounces and a cup is 8 fluid ounces. 16 ÷ 8 = 2, so one pint equals two cups. This helps when following recipes or converting quantities. If you think about the other amounts: a cup is half a pint, three cups would be 1.5 pints, and four cups would be two pints.
Question 4
One metric ton is equal to which of the following?
Correct Answer:
2,204 pounds
Explanation:
A metric ton is a large unit, and understanding how it relates to pounds helps you convert between metric and customary systems. A metric ton equals 1,000 kilograms. To get pounds, use 1 kilogram ≈ 2.20462 pounds. So 1,000 kilograms × 2.20462 ≈ 2,204.62 pounds. That means a metric ton is about 2,204 pounds, and the option listing 2,204 pounds is the closest, practical match. If you were asked in kilograms, the exact value would be 1,000 kilograms. The other choices don’t fit the question’s implied unit: 1,000 pounds is far less than a metric ton, and 2,000 kilograms is twice a metric ton.
Question 5
If events A and B are independent with P(A)=0.5 and P(B)=0.4, what is P(A and B)?
Correct Answer:
0.20
Explanation:
When two events are independent, the probability of both happening is the product of their individual probabilities. So P(A and B) = P(A) × P(B) = 0.5 × 0.4 = 0.20. The probability of both events occurring is 0.20.
