Question

An investor invested a total of $900. in two mutual funds.  One fund earned 5 percent profit while the other earned  a 3 percent profit.   If the investors total was $39., how much was invested in each mutual fund?

Answer 1

Assuming you mean 'if the investors total profit was $39'

Amount invested in first fund = X

Amount invested in second fund = 900-X

5 percent profit from the first fund = 0.05(X)

3 percent profit from the second fund = 0.03(900-X)

Total profit:

0.05(X) + 0.03(900-X) = 39

0.02(X) + 27 = 39

0.02(X) = 12

X = 600

900 - X = 300

$600 was invested in the 5% fund and 300 was invested in the 3% fund.
