#### Question

If A = {2, 3, 4, 5, 6}, then which of the following is not true?

(A) ∃ x ∈ A such that x + 3 = 8

(B) ∃ x ∈ A such that x + 2 < 5

(C) ∃ x ∈ A such that x + 2 < 9

(D) ∀ x ∈ A such that x + 6 ≥ 9

#### Solution

Since, x = 2 ∈ A does not satisfy x + 6 ≥ 9.

∴ option (D) is not true

Is there an error in this question or solution?
