Question: If SYMBOL is written as NZTMPC in a certain code, how is NUMBER…

Key idea: deduce the pattern from SYMBOL -> NZTMPC and apply it to NUMBER.

• From SYMBOL -> NZTMPC we observe that Y and O (vowels, and Y treated like a vowel here) are replaced by the next alphabet letter: Y -> Z, O -> P.

• The consonants follow an internal mapping implied by the example: S -> N, M -> O, B -> S, L -> C. (We infer these consonant substitutions from the single example given.)

Apply the rules to NUMBER (letters N U M B E R):

• N (consonant) -> N (by the consonant mapping)

• U (vowel) -> V (next letter)

• M (consonant) -> O (by the consonant mapping)

• B (consonant) -> S (by the consonant mapping)

• E (vowel) -> F (next letter)

• R (consonant) -> C (by the consonant mapping)

Putting these coded letters together gives: NVOSFC — the correct coded form of NUMBER.
