an investor invested a total of 2500 dollars in two mutual funds.one fund earned 5 percent profitwhile the other earned 3 percen
bonufazy [111]

Total investment=$2500

Let say David earned 5% profit and Harry earned 3% profit.

If <u>David</u> invested y dollar in mutual fund then <u>Harry</u> would invest,

Harry would invest,$(2500-y)

Total profit would equal to sum of 5% of money <u>David</u> invested and 3% of money <u>Harry</u> invested,

So,

5% × y +3% ×(2500-y)=<u>total profit</u>

0.05×y+0.03×(2500-y)=$111

0.05y+0.03×2500-0.03y=111

0.02y+75=111

0.02y=111-75

y=36/0.02

y=$1800

which is the amount <u>David</u> invested.

The amount invested by <u>Harry</u> would be,

=$(2500-1800)

=$700
