Answer:
q = 22
Step-by-step explanation:
Given that,
p and q are inversely proportional to each other i.e.
[tex]p=\dfrac{k}{q}[/tex]
Put p = 11 and q = 18
So,
[tex]11=\dfrac{k}{18}\\\\k=11\times 18\\\\k=198[/tex]
Now put k = 198, p = 9 and find q. So,
[tex]q=\dfrac{k}{p}\\\\q=\dfrac{198}{9}\\\\q=22[/tex]
Hence, the value of q is equal to 22.
