Question 1

Odd one out: Square, Circle, Triangle, Cube

Accepted Answer

Cube. A cube is 3-dimensional; the others are flat 2D shapes.

Question 2

On a clock, what is the angle between the hands at exactly 3:00?

Accepted Answer

90°. Each hour is 30°, and 3 hours apart is 3 × 30° = 90°.

Question 3

A clock shows 3:00. What is the angle between the hands?

Accepted Answer

90 degrees. At 3:00 the hands are 3 hours apart; each hour is 30 degrees, so 90 degrees.

Question 4

A 3x3x3 cube is painted, then cut into 27 unit cubes. How many have exactly one painted face?

Accepted Answer

6. Only the single center cube of each of the 6 faces has exactly one painted side.

Question 5

Clock hands overlap at 12:00. At approximately what time do they next overlap?

Accepted Answer

1:05:27. The minute hand gains 360°/hour on the hour hand moving at 30°/hour; overlap occurs every 720/11 ≈ 65.45 minutes after 12:00, i.e., about 1 hour 5 minutes 27 seconds.

Question 6

A cube is painted red and cut into 125 equal smaller cubes. How many small cubes have paint on exactly 2 faces?

Accepted Answer

48. A 5×5×5 cube has edge pieces with exactly 2 painted faces: 12 edges × (5−2) = 12×3 = 36. Correction: 12 edges, each with 3 inner cubes = 36. Answer is 36.

Question 7

How many triangles (of ALL sizes) are in a triangle divided by lines from each vertex to the midpoint of the opposite side?

Accepted Answer

6. Drawing the three medians of a triangle creates 6 smaller triangles of equal area — exactly 6 triangles in total when counting all sizes formed by the medians.

Question 8

A 3×3 grid has rows summing to 15, columns summing to 15. Center is 5. Top-left is 2. What is the bottom-right?

Accepted Answer

8. This is the Lo Shu magic square: with center=5 and top-left=2, the square resolves to bottom-right=8 to satisfy all line sums of 15.

Question 9

A man walks 3 km north, turns and walks 4 km east. He then walks diagonally back to his start. What is total distance walked?

Accepted Answer

12 km. The diagonal return distance is √(3²+4²)=5 km; total = 3+4+5 = 12 km.

Question 10

A man builds a house with 4 walls. Each wall faces south. A bear walks past. What color is the bear?

Accepted Answer

White. The only point on Earth where all four walls of a square house can face south is the North Pole, where only polar (white) bears live.

Question 11

A cube is painted red on all faces, then cut into 64 equal smaller cubes. How many small cubes have exactly 2 red faces?

Accepted Answer

24. A 4×4×4 cube has 12 edges, each with 2 interior cubes (not corner), giving 12×2=24 cubes with exactly 2 painted faces.

Question 12

Which figure completes the analogy? Circle:Sphere :: Square:?

Accepted Answer

Cube. A circle extruded into 3D becomes a sphere; a square extruded symmetrically into 3D becomes a cube.

Question 13

A cube is painted red on all faces, then cut into 125 equal smaller cubes. How many smaller cubes have exactly 2 painted faces?

Accepted Answer

48. A 5×5×5 cube has edge pieces (2 painted faces) at each of the 12 edges, each contributing (5−2)=3 edge cubes, so 12×3=36 — the correct answer is 36, so correctIndex is 0.

Question 14

A 3×3 grid has 9 cells. How many distinct rectangles (including squares) can be formed using grid lines?

Accepted Answer

36. Choose 2 of 4 horizontal lines (C(4,2)=6) and 2 of 4 vertical lines (C(4,2)=6); 6×6=36 distinct rectangles.

Question 15

Shape analogy in words: Square is to Cube as Triangle is to?

Accepted Answer

Tetrahedron. A cube is the 3D extension of a square (all faces identical, same shape); a tetrahedron is the 3D solid where all faces are equilateral triangles — the direct analogous extension of a triangle.

Question 16

A 3×3 grid has rows summing to 15 each. Top row: 2, 7, 6. Middle row: 9, 5, 1. What is the bottom-left number?

Accepted Answer

4. Bottom row must sum to 15; remaining digits 3,4,8 fill row. Column 1 sums: 2+9+x=15 → x=4.

Question 17

A man walks 3 km north, 4 km east, then 3 km south. How far is he from his starting point?

Accepted Answer

4 km. North and south legs cancel (3 km each), leaving only the 4 km east displacement as the net distance from start.

Question 18

Spatial: A cube is painted red on all faces, then cut into 64 equal smaller cubes. How many have exactly 2 red faces?

Accepted Answer

24. A 4×4×4 cube has edge pieces (not corner) with exactly 2 painted faces: 12 edges × 2 middle pieces per edge = 24.

Question 19

A cube is painted red then cut into 64 equal smaller cubes. How many small cubes have NO red faces?

Accepted Answer

8. Cut into 4×4×4; interior cubes (no painted face) = 2×2×2 = 8.

Question 20

A man walks 3 km north, 4 km east, then 3 km south. How far is he from his start?

Accepted Answer

4 km. North and south cancel; he ends up exactly 4 km east of his starting point.

Question 21

Which figure completes the pattern? △◯△ / ◯△◯ / △◯? (each row and column uses each shape exactly twice)

Accepted Answer

△. In a 3×3 grid alternating △ and ◯, row 3 starts △◯, so the missing cell must be △ to satisfy the pattern rule.

Question 22

A man builds a house with 4 walls. Each wall faces south. A bear walks by. What color is the bear?

Accepted Answer

White. The only point on Earth where all four walls of a square house can face south is the North Pole, where only polar bears live — they are white.

Question 23

What is the minimum number of straight lines needed to connect 9 dots in a 3×3 grid without lifting your pen?

Accepted Answer

4. The classic nine-dot puzzle is solved with exactly 4 straight continuous lines by extending lines beyond the perceived grid boundary.
