Question

Jessica invested her savings in two investment funds. The $6000 that she invested in Fund A returned a 2% profit. The amount that she invested in Fund B
returned a 6% profit. How much did she invest in Fund B, if both funds together returned a 5% profit?

Answer 1

The investment made by Jessica in Fund B is $22500

It is given that,

When Jessica made an investment of $6000 in Fund A, the return she get is 2% profit

Profit with an investment of $6000 in Fund A  = 2 %

Let x be the investment made by Jessica in Fund B

Similarly, When Jessica made second investment of $x in Fund B, the return she get is 1% profit

Profit with an investment of $x in Fund B = 1%

It is also given that,

The total profit earned by Jessica in both Fund A and Fund B = 5%

6000+x = 5%

Now, we need to find we need to find the investment made by Jessica in Fund B i.e the value of x

Therefore, we get

2 x 6000 + x = 5(6000 + x)

120000 + x = 30000 + 5x

5x -x = 120000 - 30000

4x = 90000

x = 22500

Hence, the investment made by Jessica in Fund B is $22500
