erica [24]

Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
   = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
   = 10 * 63 dollars
   = 630 dollars
Rate at which each stocks were sold = 35 1/4
   = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
   = 5 * 141 dollars
   = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".
