Question

10% more than a number is 132 What is the number

Answer 1

We want to find a number x such that 10% more of that number is equal to 132.

1) We can write the 10% of the number x as:

`(10)/(100)\cdot x=0.1x\text{.}`

2) Now, 10% more of the number x is:

`x+0.1x=1.1x\text{.}`

So we have that:

`1.1x=132.`

3) To solve the last equation, we divide both sides by 1.1:

`\begin{gathered} (1.1x)/(1.1)=(132)/(1.1), \\ x=120. \end{gathered}`

Answer

The number is 120.
