3. Q3 · Puzzles

   A, B, C, D, E, and F are six friends. A is taller than B but shorter than C. D is the tallest. E is shorter than F but taller than B. C is shorter than F. Who is the second tallest among them?

   • A. F
   • B. C
   • C. E
   • D. A
   Answer and solution

   Answer: A

   Order from tallest to shortest: D > F > C > A > E > B. Therefore, F is the second tallest.

4. Q4 · Mirror and Water Image

   If the time shown by a clock is 3:45, what will be the mirror image time when the mirror is placed vertically on the left side?

   • A. 8:15

5. Q5 · Cubes and Dice

   A cube is painted red on two opposite faces, blue on two other opposite faces, and green on the remaining two faces. It is then cut into 64 smaller identical cubes. How many smaller cubes have exactly one face painted?

   • B. 32
   • C. 28
   • D. 36
   Answer and solution

   Answer: A

   For a 4×4×4 cube, cubes with exactly one face painted are located at the center of each face: 4 faces × 2² center cubes = 4 × 4 = 16. However, adjusting for all six faces: (4-2)² × 6 = 4 × 6 = 24 cubes.
