Answer 2

Number is a = 200.

Explanation:

We know that 10% of a is 20.

So we can write the following equation:

10% * a = 20

We can rewrite 10% as
`\sf (10)/(100)` , which gives us:

`\sf (10)/(100)*a = 20`

To solve for a, we need to multiply both sides of the equation by
`\sf (100)/(10)`

`\sf \left((10a)/(100) \right) * \sf (100)/(10) = \sf 20*(100)/(10)`

`\sf a = 20*10`

`\sf a = 200`

Therefore, the number is a = 200.
