Question : 3

Total: 40

M=\{

\}

N=\{

\}

M \cup N

Solution:

Concept:

Union of two sets combines all distinct elements from both sets.

Explanation:

Multiples of 4 between 10 and 25 are:

M = \{12, 16, 20, 24\}

Even numbers between 11 and 23 are:

N = \{12, 14, 16, 18, 20, 22\}

For

M \cup N

, list every element that appears in either set, without repeating any number.

So,

M \cup N = \{12, 14, 16, 18, 20, 22, 24\}

Answer:

M \cup N = \{12, 14, 16, 18, 20, 22, 24\}

Correct option: D.
