Q11A price decreased from $640 to $544. What is the percentage decrease?

Decrease = $96; percentage decrease = (96 ÷ 640) × 100 = 15%.
Q12A warehouse has 3 shifts. Shift 1 processes 40% of daily inventory, Shift 2 processes 35%, and Shift 3 handles the rest. If Shift 3 processes 500 units, what is the total daily inventory?
✓ Correct answer: B. 2,000 units
Shift 3 handles 100% − 40% − 35% = 25% of inventory; total = 500 ÷ 0.25 = 2,000 units.
Q13A tank is filled by Pipe A at 1/4 tank per hour and simultaneously drained by Pipe B at 1/6 tank per hour. The tank starts 1/3 full. How many hours until the tank is completely full?
✓ Correct answer: A. 8 hours
Net fill rate = 1/4 − 1/6 = 1/12 per hour; remaining capacity = 2/3; time = (2/3) ÷ (1/12) = 8 hours.
Q14A contractor bids a job at $48,000. Materials cost $18,000 and labor accounts for 5/8 of the remaining amount. What is the labor cost?
✓ Correct answer: A. $18,750
Amount after materials = $48,000 − $18,000 = $30,000; labor = 5/8 × $30,000 = $18,750.
Q15A machine produces widgets at a defect rate of 1.5%. In a production run of 8,400 widgets, how many are expected to be defective?
✓ Correct answer: D. 126
Defective count = 1.5% × 8,400 = 0.015 × 8,400 = 126.
Q16A loan of $12,000 is taken out at 8% simple annual interest. After some time, the total amount owed (principal + interest) is $14,880. How many years was the loan outstanding?
✓ Correct answer: B. 3.0 years
Interest accrued = $14,880 − $12,000 = $2,880; using I = P × r × t: 2,880 = 12,000 × 0.08 × t, so t = 2,880 ÷ 960 = 3 years.
Q17A rectangular garden has a length of 12 meters and a width of 7 meters. What is the perimeter of the garden?
✓ Correct answer: D. 38 meters
Perimeter of a rectangle = 2(length + width) = 2(12 + 7) = 2(19) = 38 meters.
Q18Which of the following is equivalent to 5² × 5³?
✓ Correct answer: D. 5⁵
When multiplying powers with the same base, add the exponents: 5² × 5³ = 5^(2+3) = 5⁵.
Q19Solve for x: 4x − 9 = 19
✓ Correct answer: D. x = 7
Add 9 to both sides to get 4x = 28, then divide by 4 to get x = 7.
Q20A triangle has a base of 10 cm and a height of 6 cm. What is its area?
