[tex]\sf Hello![/tex]

[tex]\sf Let\: the \:required[/tex] % [tex]\sf be\: x[/tex]

[tex]\sf Then,[/tex]

[tex]\sf x[/tex] % × [tex]\sf 50 = \sf 9[/tex]

⇒ [tex]\dfrac{\sf x}{\sf 100} × \sf 50 = \sf 9[/tex]

⇒ [tex]\dfrac{\sf x}{\sf 2} = \sf 9[/tex]

⇒ [tex]\sf X = \sf 9 × 2[/tex]

⇒ [tex]\boxed{\sf x = 18}[/tex]

[tex]\sf Therefore, [/tex]
[tex]\sf D.\: 18[/tex] % [tex]\sf of \:50\: is \:9[/tex]
