Question 11

Jambmaths question: 

Given U ={Even number between 0 and 32 }

         P = {Multiples of 6 between 0 and 30}

         Q ={Multiples of 4 between 0 and 30}

Find ${{(P\cup Q)}^{c}}$

Option A: 

{2, 10, 14, 22, 26}

Option B: 

{0, 10, 14, 22, 26}

Option C: 

{2, 4, 14, 18, 26}

Option D: 

 {0, 2, 6, 22, 26}

Jamb Maths Solution: 

$\begin{align}  & U=\{2,4,6,8,10,12,14,16,18,20,22,24,26,28\} \\ & P=\{6,12,18,24\} \\ & Q=\{4,8.12,16,20,24,28\} \\ & P\cup Q=\{4,6,8,12,16,18,20,24,28\} \\ & {{(P\cup Q)}^{c}}=\{2,10,14,22,26\} \\\end{align}$
