RRB Technician Grade 1 Model Paper 3

Concept:The relationship is based on the alphabet positions of the letters in each pair.Each pair has a fixed difference between its two letters, and the gap between the first letters of consecutive pairs increases by 6.Explanation:Use alphabet positions: $A=1, B=2, ..., Z=26$.In the given triad $TX - IM - DH$:$T=20$, $X=24$, so $X-T=4$.$I=9$, $M=13$, so $M-I=4$.$D=4$, $H=8$, so $H-D=4$.So, in every pair, the second letter is 4 places ahead of the first letter.Now compare the first letters: $T(20) \rightarrow I(9) \rightarrow D(4)$.The differences are $9-20=-11$ and $4-9=-5$.Here, $-5 - (-11) = 6$, so the difference increases by 6.The same pattern appears for the second letters: $X(24) \rightarrow M(13) \rightarrow H(8)$, giving differences $-11$ and $-5$.Now test the options using this pattern.Option D: $AE - GK - SW$.Internal differences: $E-A=4$, $K-G=4$, $W-S=4$.First letters: $A(1) \rightarrow G(7) \rightarrow S(19)$; differences are $6$ and $12$, which increase by 6.Second letters: $E(5) \rightarrow K(11) \rightarrow W(23)$; differences are $6$ and $12$, which also increase by 6.Thus, option D follows the exact same logic as the given triad.Answer:$AE - GK - SW$
