Question
In a certain code TEACHER is written as VGCEJGT. How is CHILDREN written in that code?
Options
- EJKNFTGP
- EJKNFTGO
- EJKMFTGP
- EJLNFTGP
Show the answer and the worked solution
Correct answer: A. EJKNFTGP
Worked solution
- T → V, E → G, A → C, C → E, H → J, E → G, R → T: a shift of +2 throughout.
- Applying +2 to CHILDREN: C→E, H→J, I→K, L→N, D→F, R→T, E→G, N→P.
- The code is EJKNFTGP.
Answer: EJKNFTGP.
The idea
Write the two words one above the other and note the shift at each position. A constant shift is the commonest code of all.
Shortcut. With the +2 shift fixed, check only the letters where the options differ: I+2 = K (third), L+2 = N (fourth) and N+2 = P (last). EJKNFTGP is the only option passing all three.
Common trap. "EJKNFTGO" — shifting the final N by one place instead of two after seven correct steps; N + 2 = P.
