Question 1

Using this 5×5 cipher matrix: ★ ♠ ♣ ♥ ♦ ♣ ♥ ♦ ★ ♠ ♦ ★ ♠ ♣ ♥ ♠ ♣ ♥ ♦ ★ ♥ ♦ ★ ♠ ♣ Letters A-T map to cells in row-major order (A→★, B→♠, C→♣, D→♥, E→♦, etc.) What is the encoded form of 'CODE'?
Encoding 'CODE': C→♣ O→♥ D→♥ E→♦ = ♣♥♥♦
decoding, cipher, puzzle

Question 2

Original matrix: A B C D E F G H I After rotated-180 transformation, the matrix becomes:
Applying rotated-180 transformation yields:
I H G
F E D
C B A
transformation, geometry, rotation

Question 3

Find the missing element (?) in this matrix pattern: ★ ♠ ♣ ♠ ♣ ♥ ♣ ♥ ? What should replace the '?'?
Pattern: cyclic pattern of symbols

Step 1: Identify symbol order: ★ → ♠ → ♣ → ♥ → ♦ (cyclic)
Step 2: First row: ★, ♠, ♣ (positions 1,2,3)
Step 3: Second row: ♠, ♣, ♥ (positions 2,3,4)
Step 4: Third row: ♣, ♥, ? (positions 3,4,5)
Step 5: Position 5 in cycle is ♦
Pattern: Each row shifts one position forward in the symbol cycle

Answer: ♦

Question 4

In matrix: 1 2 3 4 5 6 7 8 9 What is the sum of anti-diagonal?
The sum of anti-diagonal: 3 + 5 + 7 = 15
numbers, matrix, arithmetic

Question 5

In matrix: 1 4 7 2 5 8 3 6 9 Which column has the minimum sum?
Column sums: Col1=6, Col2=15, Col3=24. Minimum is Column 1 with sum 6

Question 6

Original matrix: 2 4 6 8 10 12 14 16 18 After rotated-180 transformation, the matrix becomes:
Applying rotated-180 transformation yields:
18 16 14

Question 7

Original matrix: 2 4 6 8 10 12 14 16 18 After column-reversed transformation, the matrix becomes:
Applying column-reversed transformation yields:
14 16 18
8 10 12
2 4 6
transformation, geometry, rotation

Question 8

In matrix: 1 2 3 4 5 6 7 8 9 What is the sum of main diagonal?
The sum of main diagonal: 1 + 5 + 9 = 15
numbers, matrix, arithmetic

Question 9

Find the missing element (?) in this matrix pattern: 1 3 5 2 4 6 3 5 ? What should replace the '?'?
Pattern: arithmetic progression - rows increase by 2, columns increase by 1

Step 1: Observe the pattern in first row: 1 → 3 → 5 (adds 2 each time)
Step 2: Second row: 2 → 4 → 6 (also adds 2 each time)
Step 3: Third row: 3 → 5 → ? (should also add 2)
Step 4: Therefore, ? should be 7 (5 + 2)
Step 5: Check column pattern: Col1: 1,2,3 (+1), Col2: 3,4,5 (+1), Col3: 5,6,7 (+1)
Pattern: Each row increases by 2, each column increases by 1 - consistent across matrix

Answer: 7
