If EFFECTIVE is coded as FEGDDSJUF, then how RELATIVE can be written in that code?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → SDMZUHWD
Compare each letter of EFFECTIVE with the letter under it in FEGDDSJUF:
E → F (+1), F → E (−1), F → G (+1), E → D (−1), C → D (+1), T → S (−1), I → J (+1), V → U (−1), E → F (+1)
So the rule is +1 and −1 in turn, starting with +1 on the first letter.
Applying it to RELATIVE:
R + 1 = S, E − 1 = D, L + 1 = M, A − 1 = Z
T + 1 = U, I − 1 = H, V + 1 = W, E − 1 = D
