Here's the Solution to this Question

$\text{By definition we have the following: } \\ A = \{ 20k \mid k \in \mathbb{N} \} = \{ 20, 40, 60, 80, 100, 120, 140, \dots \} \\ B = \{ 15n \mid n \in \mathbb{N} \} = \{ 15, 30, 45, 60, 75, 90, 105, 120, \ldots \}\\ A \cap B = \{ 60, 120, 180, \ldots \} = \{ 60m \mid m \in \mathbb{N} \}\\ \text{Answer = A. Natural numbers multiple of 60}$ $By definition we have the following: A = {20 k ∣ k \in N} = {20, 40, 60, 80, 100, 120, 140, \dots} B = {15 n ∣ n \in N} = {15, 30, 45, 60, 75, 90, 105, 120, \dots} A \cap B = {60, 120, 180, \dots} = {60 m ∣ m \in N} Answer = A. Natural numbers multiple of 60$

Let A be the set of natural numbers multiples of 20 and B the set of natural numbers multiples of 15. Which is the set A ∩ B? A.natural numbers multiples of 60 B. natural numbers multiples of 5 C. natural numbers multiples of 300 D. natural numbers multiples of 30
