Which letter-cluster replaces # and % in:
?
NPR
OMQ
NLJ
KIM
NPR
Convert each letter to its numerical position (1-26) and check for a constant positional shift, such as adding or subtracting 12.
Convert each letter to its numerical position (1-26) and check for a constant positional shift, such as adding or subtracting 12.
Step 1: Identify the positional values
Write the 1-based alphabetical index for BDF: B=2, D=4, F=6.
Step 2: Determine the transformation rule
Applying a +12 forward shift to each letter of BDF gives: 2+12=14 (N), 4+12=16 (P), 6+12=18 (R), resulting in NPR.
Step 3: Match with the analogy structure
In the relation #: PQS:: BDF: %, the cluster # corresponds to NPR based on the identical positional shift pattern.
B: OMQ does not follow the consistent +12 positional shift rule from BDF. C: NLJ uses an incorrect backward shift instead of the required transformation. D: KIM fails to maintain the precise alphabetical distance required by the analogy.
A is correct because the letter-cluster NPR replaces #, following a strict +12 forward shift rule when mapped to BDF.
Always convert letters to their numerical 1 to 26 positions to quickly spot constant shifts or arithmetic progressions in letter-cluster analogies.
