Question 1: A 12-inch bolt is cut into pieces each 1.5 inches long. How many pieces are cut?
- 6
- 7
- 8 (Correct answer)
- 9
Correct answer: 8
12 ÷ 1.5 = 8 pieces.
Question 2: If current (I) = Voltage (V) / Resistance (R), and V = 120 V with R = 15 ohms, what is I?
- 6 A
- 8 A (Correct answer)
- 10 A
- 12 A
Correct answer: 8 A
I = 120 / 15 = 8 amperes.
Question 3: A worker earns $756 for 42 hours of work. What is the hourly rate?
- $16.00
- $17.00
- $18.00 (Correct answer)
- $19.00
Correct answer: $18.00
756 ÷ 42 = $18.00 per hour.
Question 4: Convert 3/5 to a percentage.
- 40%
- 55%
- 60% (Correct answer)
- 65%
Correct answer: 60%
3 ÷ 5 = 0.60 = 60%.
Question 5: A conduit must be bent at a 45° angle. If the run is 10 feet, how long is the diagonal section? (Use √2 ≈ 1.41)
- 11.41 ft
- 12.41 ft
- 14.10 ft (Correct answer)
- 15.00 ft
Correct answer: 14.10 ft
A 45° bend over 10 ft means the diagonal = 10 × 1.41 = 14.1 ft.
Question 6: What is 250 increased by 20%?
- 270
- 280
- 300 (Correct answer)
- 310
Correct answer: 300
250 × 1.20 = 300.
