Question

RP 4 is related to WU 16 in a certain way. In the same way, LJ 3 is related to QO 9. To which of the following is TR 6 related, following the same logic?

This question was previously asked in
RRB NTPC 2024 CBT 1 Question Paper (28-Aug-2025) (Shift 3)
The correct answer is
YW 36

Relationship Pattern: RP 4 to WU 16

The question presents an analogy between two pairs: RP 4 relates to WU 16, and LJ 3 relates to QO 9. The goal is to identify the underlying logic and apply it to find the corresponding pair for TR 6.

  • Pair 1: RP 4 $\to$ WU 16
  • Pair 2: LJ 3 $\to$ QO 9
  • Target: TR 6 $\to$ ?

Letter Transformation Logic

Analyze the positional change of letters based on their place in the alphabet:

  • For RP $\to$ WU: R (18th) $\to$ W (23rd) is a +5 shift. P (16th) $\to$ U (21st) is also a +5 shift.
  • For LJ $\to$ QO: L (12th) $\to$ Q (17th) is a +5 shift. J (10th) $\to$ O (15th) is a +5 shift.

The consistent pattern is adding 5 to the alphabetical position of each letter.

Applying this pattern to TR:

  • T is the 20th letter. $20 + 5 = 25$, which corresponds to Y.
  • R is the 18th letter. $18 + 5 = 23$, which corresponds to W.

The letter transformation results in YW.

Number Transformation Logic

Examine the relationship between the numbers in the pairs:

  • For 4 $\to$ 16: The relationship is $4^2 = 16$.
  • For 3 $\to$ 9: The relationship is $3^2 = 9$.

The consistent pattern is squaring the number.

Applying this pattern to the number 6:

  • $6^2 = 36$.

The number transformation results in 36.

TR 6 Relation Application

Combining the results of the letter transformation (YW) and the number transformation (36), the complete pair for TR 6 is YW 36.

This matches Option B.
