Concept:The relation is that the second number is obtained by subtracting 18 from the first number.Explanation:For X:98, the pattern gives X−18=98.So, X=98+18=116.For 196:Y, the same pattern gives 196−18=Y.So, Y=178.Thus, the pair becomes 116:98::196:178.This matches Option D.Answer:X=116, Y=178 (Option D).
