Question 1

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

Question 2

If @=C, #=L, $=O, ... then decode: '@#$%&'
Reverse mapping: @#$%& → CLOUD = CLOUD
reverse, decoding

Question 3

If +=~, -=*, *=@, /=#, then evaluate: 1 @ 1 # 4
Decode symbols: 1 @ 1 # 4 → 1 * 1 / 4 = 0
arithmetic, operations

Question 4

If +=$, -=%, *=~, /=*, then evaluate: 7 * 5 $ 2
Decode symbols: 7 * 5 $ 2 → 7 / 5 + 2 = 3
arithmetic, operations

Question 5

If vowels at even positions (1-based) = @, vowels at odd positions = #, consonants remain same, then 'MONITOR' = ?
Vowels at positions: M, O(pos2,even→@), N, I(pos4,even→@), T, O(pos6,even→@), R = M#N#T#R
conditional, rules

Question 6

If first and last letters = &, others = *, then 'SCIENCE' = ?
First-last special: S(first)=&, E(last)=&, middle letters=* → &*&
pattern, position

Question 7

If +=&, -=%, *=^, /=*, then evaluate: 6 & 8 * 8
Decode symbols: 6 & 8 * 8 → 6 + 8 / 8 = 7
arithmetic, operations

Question 8

If vowels at even positions (1-based) = @, vowels at odd positions = #, consonants remain same, then 'KEYBOARD' = ?
Vowels at positions: K, E(pos2,even→@), Y, B, O(pos5,odd→#), A(pos6,even→@), R, D = K#YB@#RD
conditional, rules

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 middle letter = !, all others = ^, then 'COMPUTATION' = ?
Middle special: T(position 6)→!, others→^ → ^^^^^!^^^^^
pattern, position

Question 11

If E=#, O=%, H=6, N=!, P=?, then 'PHONE' is coded as?
Applying symbol substitution: P→? → H→6 → O→% → N→! → E→# = ?6%!#
substitution, basic

Question 12

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

Question 13

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

Question 14

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

Question 15

If E=#, O=%, U=&, H=6, S=-, then 'HOUSE' is coded as?
Applying symbol substitution: H→6 → O→% → U→& → S→- → E→# = 6%&-#
substitution, basic

Question 16

If A=@, E=#, R=+, T==, W=~, then 'WATER' is coded as?
Applying symbol substitution: W→~ → A→@ → T→= → E→# → R→+ = ~@=#+
substitution, basic

Question 17

If +=$, -=*, *=^, /=@, then evaluate: 2 $ 4 * 10
Decode symbols: 2 $ 4 * 10 → 2 + 4 - 10 = -4
arithmetic, operations

Question 18

If vowels = $, consonants = %, then 'DATABASE' = ?
Vowel-consonant coding: vowels (A, A, A, E)→$, consonants (D, T, B, S)→% → %$%$%$%$
pattern, position

Question 19

If E=#, O=%, P=?, R=+, W=~, then 'POWER' is coded as?
Applying symbol substitution: P→? → O→% → W→~ → E→# → R→+ = ?%~#+
substitution, basic

Question 20

If +=*, -=&, *=#, /=%, then evaluate: 2 # 9 % 12
Decode symbols: 2 # 9 % 12 → 2 * 9 / 12 = 0
arithmetic, operations
