Question

Given the universal set $\{x:xϵN,10<x<15\}$. List the elements for $A=\{x:x>10\}$

• A. $\{10,11,12,13,14,15\}$
• B. $\{11,12,13,14\}$
• C. $\{10,15,16,17\}$
• D. None of the above

Answer 1

Answer: (B)

$\{11,12,13,14\}$

The universal set is given by $\{x:x\in N.10<x<15\}$.

Hence the elements of the universal set is $\{11,12,13,14\}$

Now $A=\{x:x>10\}$

Hence elements of $A=\{11,12,13,14\}$
