Question

The number of people who own computer in a small town is 2400, which is 60% more than the number who owned computer last year. Find the number of people who owned computers last year.

Answer 1

The number of people who owned computers last year was 1500.

Explanation:

The information provided is as follows:

• The number of people who own computer in a small town is 2400.
• This is 60% more than the number who owned computer last year.

Let X denote the number of people who owned computer last year.

And Y denote the number of people who owned computer this year.

Then:

Y = X × (100% + 60%)

`2400=X* 1.60\\\\X=(2400)/(1.60)\\\\X=1500`

Thus, the number of people who owned computers last year was 1500.
