Select the option from the given alternatives which will come in place of ?
EXI : 5X9 :: NXS : __?__
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 14X19
The rule is read off the first pair: in EXI → 5X9, the outer letters are replaced by their positions in the alphabet and the middle X stays.
E = 5 and I = 9, so EXI becomes 5X9
N = 14 and S = 19, so NXS becomes 14X19
Tip: The positions of E, J, O, T, Y are 5, 10, 15, 20, 25. Knowing these five, any letter’s position is found by counting one or two steps from the nearest of them (N is one before O, so 14; S is one before T, so 19).
