Question

Select the pair that follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern. IFX : LCS DNG : GKB

• A. UIR : XMM
• B. KKK : NNG
• C. VHP : YJK
• D. BFO : ECJ

Answer 1

Answer:

D. BFO : ECJ

The correct option that follows the pattern is BFO : ECJ.

To find the correct pair, let's analyze the positional shifts of the letters in the alphabetical sequence ($A = 1, B = 2, \dots, Z = 26$):

Analyzing Pair 1: IFX : LCS

• I $\rightarrow$ L: $9 + 3 = 12$ (+3)

• F $\rightarrow$ C: $6 - 3 = 3$ (-3)

• X $\rightarrow$ S: $24 - 5 = 19$ (-5)

Analyzing Pair 2: DNG : GKB

• D $\rightarrow$ G: $4 + 3 = 7$ (+3)

• N $\rightarrow$ K: $14 - 3 = 11$ (-3)

• G $\rightarrow$ B: $7 - 5 = 2$ (-5)

Detailed Pattern Analysis:

The letters shift positionally using the exact rule [+3, -3, -5]:

1. First Letter (+3):

   • $B (2) + 3 = E (5)$

2. Second Letter (-3):

   • $F (6) - 3 = C (3)$

3. Third Letter (-5):

   • $O (15) - 5 = J (10)$

Why the other choices are incorrect:

• UIR : XMM $\rightarrow$ Uses [+3, +4, -5]

• KKK : NNG $\rightarrow$ Uses [+3, +3, -4]

• VHP : YJK $\rightarrow$ Uses [+3, +2, -5]
