If 'WATER' is coded as 'XBUFS', then 'FIRE' will be coded as:
GJSF
GJSE
HJSF
GJSG
GJSF
Quick Trick: Observe the alphabetical shift: each letter in the word is replaced by the immediate next letter in the English alphabet (N+1 rule).
Observe the alphabetical shift: each letter in the word is replaced by the immediate next letter in the English alphabet (N+1 rule).
Analyze the coding pattern
Compare WATER to XBUFS: W(+1)=X, A(+1)=B, T(+1)=U, E(+1)=F, R(+1)=S. The rule is each letter + 1 position.
Apply the rule to FIRE
Apply +1 shift to each letter: F+1=G, I+1=J, R+1=S, E+1=F. The coded word is GJSF.
B: Ends in E instead of F; C: Starts with H instead of G; D: Ends in G instead of F.
A is correct because applying the +1 shift to each letter of FIRE results in GJSF.
For coding-decoding questions, always check the first two letters; if they yield a unique option, you can save time by not calculating the entire word.
