Question 1

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'COPY'
Layer 1: COPY → C=3, O=15, P=16, Y=25 = 3151625
Layer 2: 3151625 → $@&@*#&
multilayer, complex

Question 2

If consonants at even positions = #, odd positions = *, vowels remain same, then 'COMPUTER' = ?
Consonants at positions: C(pos1→*), O, M(pos3→*), P(pos4→#), U, T(pos6→#), E, R(pos8→#) = #O#*U*E*
conditional, rules

Question 3

If vowels = $, consonants = %, then 'INTELLIGENCE' = ?
Vowel-consonant coding: vowels (I, E, I, E, E)→$, consonants (N, T, L, L, G, N, C)→% → $%%$%%$%$%%$
pattern, position

Question 4

If letters repeat pattern @, #, $ in order, then 'INTELLIGENCE' = ?
Triplet pattern: positions 1,4,7...=@, 2,5,8...=#, 3,6,9...=$ → @#$@#$@#$@#$
pattern, position

Question 5

If +=&, -=$, *=%, /=^, then evaluate: 6 % 8 $ 10
Decode symbols: 6 % 8 $ 10 → 6 * 8 - 10 = 38
arithmetic, operations

Question 6

Using the symbol matrix: E → # | B → ! | H → * | C → = | G → % Code the word: 'HBEEH'
Using matrix: H→* → B→! → E→# → E→# → H→* = *!##*
matrix, mapping

Question 7

If letters at even positions (1-based) = @, odd positions = #, then 'SCIENCE' = ?
Alternating pattern: positions 1,3,5,7... = @, positions 2,4,6... = # → @#@#@#@
pattern, position

Question 8

If @=S, #=P, $=A, ... then decode: '@#$%&'
Reverse mapping: @#$%& → SPACE = SPACE
reverse, decoding

Question 9

If I=$, U=&, C=2, M=0, S=-, then 'MUSIC' is coded as?
Applying symbol substitution: M→0 → U→& → S→- → I→$ → C→2 = 0&-$2
substitution, basic

Question 10

If I=$, U=&, C=2, M=0, S=-, then 'MUSIC' is coded as?
Applying symbol substitution: M→0 → U→& → S→- → I→$ → C→2 = 0&-$2
substitution, basic

Question 11

If vowels = @, even position consonants = #, odd position consonants = *, then 'MONITOR' = ?
Position-wise coding: M(pos 1, even)→#, O(vowel)→@, N(pos 3, even)→#, I(vowel)→@, T(pos 5, even)→#, O(vowel)→@, R(pos 7, even)→# = #@#@#@#
conditional, rules

Question 12

If Layer 1: Even positions=^, Odd positions=&, Layer 2: ^=~, &=%, then code 'PAGE'
Layer 1: PAGE (positions) → ^&^&
Layer 2: ^&^& → ~%~%
multilayer, complex

Question 13

If Layer 1: Even positions=^, Odd positions=&, Layer 2: ^=~, &=%, then code 'COPY'
Layer 1: COPY (positions) → ^&^&
Layer 2: ^&^& → ~%~%
multilayer, complex

Question 14

If middle letter = !, all others = ^, then 'ALGORITHM' = ?
Middle special: R(position 5)→!, others→^ → ^^^^!^^^^
pattern, position

Question 15

If vowels = @, even position consonants = #, odd position consonants = *, then 'PROGRAM' = ?
Position-wise coding: P(pos 1, even)→#, R(pos 2, odd)→*, O(vowel)→@, G(pos 4, odd)→*, R(pos 5, even)→#, A(vowel)→@, M(pos 7, even)→# = #*@*#@#
conditional, rules

Question 16

If A=@, E=#, G=5, M=0, then 'GAME' is coded as?
Applying symbol substitution: G→5 → A→@ → M→0 → E→# = 5@0#
substitution, basic

Question 17

If +=&, -=^, *=*, /=~, then evaluate: 11 * 1 ^ 5
Decode symbols: 11 * 1 ^ 5 → 11 * 1 - 5 = 6
arithmetic, operations

Question 18

If @=M, #=O, $=U, ... then decode: '@#$%&'
Reverse mapping: @#$%& → MOUSE = MOUSE
reverse, decoding

Question 19

If middle letter = !, all others = ^, then 'DATABASE' = ?
Middle special: B(position 5)→!, others→^ → ^^^^!^^^
pattern, position

Question 20

Using the symbol matrix: F → % | G → = | A → # | C → + | D → * Code the word: 'DGFD'
Using matrix: D→* → G→= → F→% → D→* = *=%*
matrix, mapping
