  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?

    Answer: A smaller triangle

    Folding a square diagonally gives a triangle; folding that triangle diagonally again gives a smaller triangle.

  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?

    Answer: 60

    Net fill rate = 15 − 9 = 6 liters/min; time = 360/6 = 60 minutes.

  3. CONDUCTOR : ORCHESTRA :: EDITOR : ___

    Answer: Newspaper

    A conductor leads an orchestra; an editor leads and shapes a newspaper.

  4. Which of these correctly shows the next step if the pattern is: multiply by 3 then subtract 4: 2, 2, 2, 2?

    Answer: 2

    2 × 3 = 6; 6 − 4 = 2; the pattern produces 2 indefinitely.

  5. In a mechanical system, a pulley with a fixed axle changes:

    Answer: The direction of force only

    A single fixed pulley redirects the force without changing its magnitude.

  6. A typist makes 3 errors per 400 words. At this rate, approximately how many errors will appear in a 2,000-word document?

    Answer: 15

    Error rate = 3/400; errors in 2,000 words = 3 × (2,000/400) = 3 × 5 = 15.

  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?

    Answer: $57,500

    Total = (5 × 45,000) + (2 × 80,000) = 225,000 + 160,000 = 385,000; average = 385,000/7 = $55,000.
