Worked practice questions
In a code language, ROSE is coded as SPTF (each letter shifted by +1). How is LILY coded?
- KHKX
- MIMZ
- MJMZ
- MJIZ
Show answer and solution
Correct answer: C. MJMZ
+1 shift on each letter: R→S, O→P, S→T, E→F (SPTF).
**Apply same to LILY:** L→M, I→J, L→M, Y→Z = MJMZ.
In a coded language, if HAPPY = IBQQZ, then how is SAD coded?
- RBE
- TBC
- UBF
- TBE
Show answer and solution
Correct answer: D. TBE
Each letter shifted by +1. H→I, A→B, P→Q, P→Q, Y→Z. So SAD: S→T, A→B, D→E = TBE.
