Answer: [tex]\frac{10}{9} x\text{ milliliter}[/tex]
Step-by-step explanation:
Let the volume of full bottle is y milliliter.
According to the question,
[tex]90\% \text{ of } y = x[/tex]
[tex]\frac{90}{100} y = x[/tex]
[tex]\frac{9}{10} y = x[/tex]
[tex]y=\frac{10}{9} x[/tex]
Thus, the volume of full bottle = [tex]\frac{10}{9} x\text { milliliter}[/tex]
⇒ Option A is correct.
