Question

Three friends are starting a new exercise equipment franchise. Their investments are in the ratio of 5:7:11. The smallest investor is contributing $75,000. What is the largest investor contributing?

Answer 1

Given:

Ratio of investments are 5:7:11.

Contribution of smallest investor = $75,000

To find:

The contribution of largest investor.

Solution:

Let the contribution of three friends be 5x, 7x and 11x respectively.

Here, 5x is smallest and 11 is largest.

The smallest investor is contributing $75,000.

`5x=75000`

Divide both sides by 5.

`x=15000`

Now,

`\text{Contribution of largest investor}=11x`

`\text{Contribution of largest investor}=11(15000)`

`\text{Contribution of largest investor}=165000`

Therefore, the contribution of largest investor is $165,000.
