Question

KH 13 is related to ID 2 in a certain way. In the same way, LO 9 is related to JK −2. To which of the following is LJ 7 related, following the same logic?

1. A. JG −6
2. B. KF −4
3. C. KG −6
4. D. JF −4 (Correct answer)

Correct Answer

Option D — JF −4

Detailed Solution & Explanation

The correct answer is JF −4.

Key Points

• Compare each component of the given pairs separately:
  • KH 13 → ID 2: K−2=I, H−4=D, 13−11=2
  • LO 9 → JK −2: L−2=J, O−4=K, 9−11=−2
• The rule is therefore first letter −2, second letter −4, number −11.
• Applying it to LJ 7:
  • L−2 = J, J−4 = F, 7−11 = −4
• The answer is JF −4.

Additional Information

• Treat a mixed letter-number analogy as three independent sequences, not one combined pattern. Each component follows its own rule, and testing them separately is what makes the question tractable.
• Verify the rule against both given pairs before applying it. A rule that fits only the first pair is usually a coincidence.
• The number rule must be allowed to go negative — 7 − 11 = −4. Candidates who assume results stay positive discard the correct option.
• Alphabet positions make the letter shifts quick to check: L=12 → J=10, J=10 → F=6.
