Select the option that is related to the third letter-pair in the same way as the second letter pair is related to the first letter-pair
CH : FP : : GK : ?
C : 3 , H : 8 : : F : 6 , P : 16
F - C = 6 - 3 = 3Â
P - H = 16 - 8 = 8Â
similarly , G : 7 , K : 11Â
So, 7 + 3 = 10 : J
So, 11 + 8 = 19 : S
Hence , option A is correct.Â
