Answer:

Option C.

Explanation:

Let the unknown number be x.

It means 10% of x is 81.

x\times \dfrac{10}{100}=81

x\times \dfrac{1}{10}=81

\dfrac{x}{10}=81

Multiply both sides by 10 to find the value of x.

\dfrac{x}{10}\times 10=81\times 10

x=810

The value of x is 810. It means 10% of 810 is 81.

Therefore, the correct option is C.
