Instruction: In a certain coding system: ‘dream focus build skill’ is coded as ‘trq, xnz, hmd, clv’ ‘focus logic dream’ is coded as ‘trq, jkp, xnz’ ‘trust logic build dream’ is coded as ‘xnj, clv, jkp, trq’ Question: What is the code for ‘build skill logic trust’?
- (a)clv, hmd, jkp, xnj
- (b)clv, xnj, jkp, trq
- (c)hmd, xnz, jkp, xnj
- (d)hmd, clv, xnj, xnz
Answer
Why
Correct — A. Rule: a word two sentences share takes the code their codes share.
dream is in all three sentences, trq in all three codes: dream = trq.
Sentences 1 and 3 share dream and build, codes trq and clv: build = clv.
Sentences 2 and 3 share dream and logic, codes trq and jkp: logic = jkp.
Left over: skill = hmd (sentence 1), trust = xnj (sentence 3).
build skill logic trust = clv, hmd, jkp, xnj → option (a).
Why the others are wrong
- (b)clv, xnj, jkp, trq — trq is the code for dream, which the question does not contain. Putting it in leaves out hmd, the code for skill.
- (c)hmd, xnz, jkp, xnj — xnz is the code for focus, which the question does not contain. It stands where clv, the code for build, belongs.
- (d)hmd, clv, xnj, xnz — xnz is the code for focus again, and jkp, the code for logic, is missing. The other three codes, hmd, clv and xnj, are right.
Concept
In a sentence code each word keeps one code, but the codes are not printed in word order. Sentence 1 has build third and skill fourth, yet build turns out to be clv, the fourth code.
So never match by position. Match by overlap: the words two sentences share must take the codes their codes share.
Start with the word that appears most often. dream is in all three sentences, and trq is the one code that appears in all three codes. Each word you fix shrinks the next overlap to a single pair.
The four options list their codes in different orders. Treat each option as a set: what decides it is which four codes it contains, not where they sit.
Key facts
- dream = trq, focus = xnz, build = clv, skill = hmd.
- logic = jkp and trust = xnj.
- In sentence 1, build is the third word but clv is the fourth code, so position does not carry over.

Common traps
- Matching words to codes by position, which the jumbled order makes unreliable.
- Choosing an option with three right codes and one borrowed from a word the question lacks, such as xnz for focus.
