Brian invested $ 4000 in Fund B, if both funds together returned a 5% profit

Solution:

Given, Brian invested his savings in two investment funds.  

The $6000 that he invested in Fund A returned 7% profit.  

The amount that he invested in Fund B returned a 2% profit.  

We have to find how much did he invest in Fund B, if both funds together returned a 5% profit?

Let the amount invested in Fund B be n.

Then, 5% of (6000 + n ) = 7% of 6000 + 2% of n

Hence, the amount invested in fund b is $4000.
