Goran invested his savings in two investment funds. The $4000 that he invested in Fund A returned a 5% profit. The amount that he invested in Fund B returned a 2% profit.

How much did he invest in Fund B, if both funds together returned a 3% profit?

Goram invested $4000 in fund A and returned 5 profit

Thus,$profit=\frac{4000\times 5}{100}=200$

Let x invented in fund B and returned 2 profit

$profit=\frac{x\times 2}{100}=\frac{x}{50}$

Total fund$=4000+x$ and returned 3 profit

$profit=\frac{(4000+x)\times 3}{100}$

$=\frac{12000}{100}+\frac{3x}{100}$

$=120+\frac{3x}{100}$

And$Both\text{}funds\text{}profit=Fund\text{}A\text{}profit+Fund\text{}B\text{}profit$

$120+\frac{3x}{100}=200+\frac{x}{50}$

$\frac{3x}{100}-\frac{x}{50}=80$

$\frac{3x-2x}{100}=80$

$x=100\times 80$

$=8000$

Thus,

Let x invented in fund B and returned 2 profit

Total fund
