Aldo invested his savings in two investment funds. The $24, 000that he invested in Fund A returned a 1% profit. The amount that he invested in Fund B returned a 5% profit. How much did he invest in Fund B, if both funds together returned a 2% profit?

Answer 1

$X in plan A @ 1% profit.
$(24000-X) in plan B @ 5% profit.

1.01x + 1.05(24000-x) = 1.02*24000,
1.01x + 25,200 - 1.05x = 24,480,
-0.04x = 24,480 - 25,200 = -720,
X = $18,000 Invested in fund A.

24000 - x = 24000 - 18,000 = $6,000 Invested in fund B.
