Question 1: If you fold a square piece of paper diagonally in half and then fold it diagonally in half again, what shape do you get?
- A smaller triangle (Correct answer)
- A rectangle
- A smaller square

Correct answer: A smaller triangle
Folding a square diagonally gives a triangle; folding that triangle diagonally again gives a smaller triangle.
Question 2: A water tank fills at 15 liters per minute and drains at 9 liters per minute simultaneously. If the tank holds 360 liters and starts empty, how many minutes to fill it?
- 60 (Correct answer)
- 24
- 40
- 45
Correct answer: 60
Net fill rate = 15 − 9 = 6 liters/min; time = 360/6 = 60 minutes.
Question 3: CONDUCTOR : ORCHESTRA :: EDITOR : ___

A conductor leads an orchestra; an editor leads and shapes a newspaper.
Question 4: Which of these correctly shows the next step if the pattern is: multiply by 3 then subtract 4: 2, 2, 2, 2?
- 2 (Correct answer)
- 6
- −2
- 4
Correct answer: 2
2 × 3 = 6; 6 − 4 = 2; the pattern produces 2 indefinitely.
Question 5: In a mechanical system, a pulley with a fixed axle changes:
- The direction of force only (Correct answer)
- Both force and direction
- The magnitude of force only
- Neither force nor direction
Correct answer: The direction of force only
A single fixed pulley redirects the force without changing its magnitude.
Question 6: A typist makes 3 errors per 400 words. At this rate, approximately how many errors will appear in a 2,000-word document?
- 15 (Correct answer)
- 12
- 20
- 9
Correct answer: 15
Error rate = 3/400; errors in 2,000 words = 3 × (2,000/400) = 3 × 5 = 15.
Question 7: An office has 5 employees who each earn $45,000 per year and 2 managers who each earn $80,000 per year. What is the average annual salary for all 7 employees?
- $55,000
- $62,500
- $52,500
- $57,500 (Correct answer)
Correct answer: $57,500
Total = (5 × 45,000) + (2 × 80,000) = 225,000 + 160,000 = 385,000; average = 385,000/7 = $55,000.
