conversations.value: Robi and Rudy contributed money to start a business that could earn them profit. Robi contributed $4000, and Rudy contributed 1/4 more money than Robi. If they made a profit of 20 percent of the total amount and decided to share the profits equally, calculate the amount of money each got.
  Give me a clear explanation.

conversations.value: 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
