Question

If $A=\{2,3,4,8,10\},B=\{3,4,5,10,12\}$ and $C=\{4,5,6,12,14\},$ which of the elements are part of $A\cap (B\cup C)$

• A. 3
• B. 4
• C. 10
• D. 12

Answer 1

Answer: (A), (B), (C)

The correct options are
A 3
B 10
C 4

we have

$A=\{2,3,4,8,10\},B=\{3,4,5,10,12\}$ and $C=\{4,5,6,12,14\}$

$(B\cup C)$= {3,4,5,6,10,12,14}

$A\cap (B\cup C)=\{2,3,4,8,10\}\cap \{3,4,5,6,10,12,14\}=\{3,4,10\}$

thus answer is options A B C
