  1. A rectangle has a perimeter of 54 cm and a length of 18 cm. What is its width?

    Answer: 9 cm

    Perimeter = 2(l + w), so 54 = 2(18 + w), meaning w = 27 − 18 = 9 cm.

  2. Which shape completes the matrix if the third row follows the same rule as the first two rows (each row has a triangle, circle, and square in some order)?

    Answer: Triangle

    If the first two rows each contain one triangle, one circle, and one square, the missing shape in the third row must be a triangle.

  3. MEND is to REPAIR as RAZE is to ___

    Answer: Demolish

    Mend and repair are synonyms meaning to fix; raze means to demolish completely.

  4. If today is Wednesday, what day will it be 100 days from now?

    Answer: Friday

    100 ÷ 7 = 14 remainder 2, so 100 days later is 2 days after Wednesday = Friday.

  5. All athletes exercise regularly. Maria exercises regularly. Which conclusion is valid?

    Answer: Maria may or may not be an athlete

    Exercising regularly is a necessary but not sufficient condition for being an athlete in this argument.

  6. What is the next number: 1, 4, 9, 16, 25, ___?

    Answer: 36

    These are perfect squares: 1², 2², 3², 4², 5², so next is 6² = 36.

  7. A project takes 6 workers 8 days to complete. How many days would it take 4 workers at the same rate?

    Answer: 12 days

    Total work = 6 × 8 = 48 worker-days; 48 ÷ 4 workers = 12 days.
