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
