In letter coding type of questions, the real alphabets in a word are replaced be certain other alphabets according to a specific rule to form its code. The candidate is required to detect the common rule and answer the questions accordingly.
If TAP is coded as SZO, then how is FREEZE coded ?
Clearly, each letter in the TAP is moved one step backward to obtain the corresponding letter of the code.
(S ← T), (Z ← A) and (O ← P)
Thus, in FREEZE, F will be coded as E, (R as Q), (E as D), (Z as Y).
So, the code become EQDDYD.
Hence, the answer is (d).
