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.
[tex]5x=75000[/tex]
Divide both sides by 5.
[tex]x=15000[/tex]
Now,
[tex]\text{Contribution of largest investor}=11x[/tex]
[tex]\text{Contribution of largest investor}=11(15000)[/tex]
[tex]\text{Contribution of largest investor}=165000[/tex]
Therefore, the contribution of largest investor is $165,000.
