2% of 9% of a number is what percentage of that number?

Correct option is D

Given:

We are asked to find what percentage 2% of 9% of a number is of that number.

Formula Used:

Percentage of a number = $$\frac{\text{Value}}{\text{Original number}} \times 100$$​​

Solution:

Let the number be x

Now, 

2% of 9% of x 

​$$= \frac{2}{100}\times \frac{9}{100}\times x$$​​

​$$= \frac{18 x}{100 \times 100}$$​​

= 0.0018x

So, 

Percentage = $$\frac{0.0018x}{x} \times 100 = 0.18\%$$​​
