NFST Logical and Spatial Reasoning 5 — Questions and Answers
Question 1: A number grid shows — Row 1: 2, 4, 8 | Row 2: 3, 9, 27 | Row 3: 4, 16, ___. What fills the blank?
- 32
- 48
- 64 (Correct answer)
- 128
Correct answer: 64
Each row follows n, n², n³; for row 3 starting with 4: 4¹=4, 4²=16, 4³=64.
Question 2: If you rotate a right-pointing arrow (→) 270° clockwise, which direction does it now point?
- Left (←)
- Up (↑) (Correct answer)
- Right (→)
- Down (↓)
Correct answer: Up (↑)
90° CW → down, 180° CW → left, 270° CW → up.
Question 3: What is the next number in the sequence: 1, 4, 9, 16, 25, ___?
- 30
- 34
- 36 (Correct answer)
- 49
Correct answer: 36
These are perfect squares: 1², 2², 3², 4², 5², and 6² = 36.
Question 4: Which regular polygon has the greatest number of lines of symmetry among these options?
- Equilateral triangle (3 lines)
- Square (4 lines)
- Regular hexagon (6 lines) (Correct answer)
- Rectangle (2 lines)
Correct answer: Regular hexagon (6 lines)
A regular hexagon has 6 lines of symmetry, more than any other shape listed.
Question 5: A small box measuring 3×4×5 units is packed into a large box measuring 6×8×10 units. How many small boxes fit inside?
- 4
- 6
- 8 (Correct answer)
- 16
Correct answer: 8
Each dimension doubles exactly: (6÷3)×(8÷4)×(10÷5) = 2×2×2 = 8.
Question 6: All axes are tools. All tools require maintenance. Which statement is definitely true?
- All tools are axes
- Some axes require maintenance
- All axes require maintenance (Correct answer)

Question 7: An evacuation grid labels rooms by row (number) and column (letter). Room 1A is the entrance; Room 3C is 2 rows down and 2 columns right. Which room is the midpoint between them?
- 1C
- 2B (Correct answer)
- 3A
- 2C
Correct answer: 2B
Midpoint row = (1+3)÷2 = 2; midpoint column = (A+C)÷2 = B; so the midpoint room is 2B.
