Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of ::?
# : JLH :: IKG : %

Correct option is C

Given - # : JLH :: IKG : %
Option (A):
# = FJH, % = MHU
Check if FJH → JLH
 F + 4 = J
 J + 2 = L
 H + 0 = H
Pattern: +4, +2, +0
Now apply this same pattern to IKG:
I + 4 = M
K + 2 = M
G + 0 = G
We get: MMG But given % = MHU  (Not followed)

Option (B):
# = DEG, % = NIU
Check if DEG → JLH
 D + 6 = J
 E + 7 = L
 G + 1 = H
Pattern: +6, +7, +1
Try applying it to IKG:
I + 6 = O
K + 7 = R
G + 1 = H
We get: ORH , But % = NIU (Not followed)

 Option (C):
# = EGC, % = NPL
Check if EGC → JLH
E  +5 = J
G +5 = L
C  +5 = H
Logic =  Pattern: +5, +5, +5
Apply to IKG:
I + 5 = N
K + 5 = P
G + 5 = L
We get: NPL , % = NPL → Matches (Option C is correct.)

 Option (D)
# = FDG, % = MLG
Check FDG → JLH
F  +4 = J
D  +8 = L
G  +1 = H
 Not a consistent pattern
Apply to IKG:
I + 4 = M
K + 8 = S
G + 1 = H
Gives MSH, but % = MLG , Option (D) is incorrect

Option C is correct.
