Q7.If in a certain code TEACHER is written as VGCEJGT, how would STUDENT be…

Concept: In an alphabet-shift coding scheme, each letter of a word is replaced by the letter reached after moving forward the same fixed number of alphabet positions, applied to every letter in its original left-to-right order — one constant offset for the whole word.

Application:

1. Compare TEACHER (T, E, A, C, H, E, R) with its code VGCEJGT (V, G, C, E, J, G, T), letter by letter: T→V, E→G, A→C, C→E, H→J, E→G, R→T. Every letter moves forward by exactly 2 positions, so the offset used in this code is +2.

2. Apply the same +2 shift to each letter of STUDENT (S, T, U, D, E, N, T), in the same left-to-right order: S→U, T→V, U→W, D→F, E→G, N→P, T→V.

3. Reading the shifted letters in order gives the encoded word: U-V-W-F-G-P-V.

Cross-check: Decode this result back by moving each letter 2 positions backward: U→S, V→T, W→U, F→D, G→E, P→N, V→T, which reassembles to S-T-U-D-E-N-T — the original word. This confirms the shift was applied correctly, to every letter, in the right order.

So the sequence obtained by consistently applying the +2 shift to STUDENT is the one that represents it under this code.
