If Robi contributed $4000, then Rudy contributed 1 / 4 * 4000 = $1000 more. The total amount of money Rudy contributed is $4000 + $1000 = $5000. Together, the contributed a total of $5000 + $4000 = $9000. They made a 20% profit, a total of 20 / 100 * $9000 = $1800. When they decided to share the profit equally, each received $1800 / 2 = $900.
Therefore, the answer is 900.
