I believe you left out the words 'than if' in the last sentence of your question :-)

To determine how much each person gets if the profits are divided proportionally:

Total invested=$9000+$7000+$4000=$20000

X invested $9000 or 9000/20000 of total

9000/20000 reduces to 9/20 = .45 = 45%

Y invested $7000 or 7000/20000 of total

7000/20000 reduces to 7/20 = .35 = 35%

Z invested $4000 or 4000/20000

4000/20000 reduces to 4/20 = 1/5 = .2 = 20%

So if the profits of $4800 are split proportionally you get (Profits * %invested)

X gets $2160

Y gets $1680

Z gets $960

If you split the profits equally

$4800 / 3 people = $1600

For X, the proportional total (2160) minus equal total (1600) is $560.

This is a type of problem you'll encounter a lot in life :)
