Difficulty: Medium
Correct Answer: Both Statements I and II together are sufficient, but neither alone is sufficient.
Explanation:
Introduction / Context:We must isolate the digit-code corresponding to the word 'habit' by using overlaps across coded sentences.
Given Data / Assumptions:
Concept / Approach:Use intersection: the common word 'good' between 146 and 143 implies its code is shared between {1,4}; then intersect 146 with 826 to pin the remaining common word as 'habit(s)'.
Step-by-Step Solution:
Common(146,143) → word 'good' ↔ code ∈ {1,4}.Common(146,826) → shared code = 6; shared word = habit(s) ⇒ 'habit' ↔ 6.Individually, neither I nor II alone can isolate the code for 'habit'; together they do.Verification / Alternative check:Remaining codes pair consistently with the other words without contradiction.
Why Other Options Are Wrong:
Common Pitfalls:Being distracted by plural 'habits' vs singular 'habit'; in such code problems stems map identically.
Final Answer:E — Together sufficient (code for 'habit' = 6).
