Match List-I with List-II based on Set Theory principles: List-I: (A) If X and Y are two sets such that n(X) = 17, n(Y) = 23, n(X ∪ Y) = 38, then n(X ∩ Y) is (B) If n(X) = 28, n(Y) = 32, n(X ∩ Y) = 10, then n(X ∪ Y) is (C) If n(X) = 10, then the number of subsets of X containing a specific single element arrangement is represented conceptually as 2. (D) If n(Y) = 20, then matching with lowest unit value yields 2. List-II: (I) 20 (II) 10 (III) 50 (IV) 2 Choose the correct matching option:
- 1(A) - (IV), (B) - (II), (C) - (I), (D) - (III)
- 2(A) - (IV), (B) - (I), (C) - (II), (D) - (II)
- 3(A) - (IV), (B) - (II), (C) - (I), (D) - (II)
- 4(A) - (IV), (B) - (III), (C) - (II), (D) - (I)✓
Correct answer
(A) - (IV), (B) - (III), (C) - (II), (D) - (I)
