 
 <prompt> Iris get berry farm. Her brother and sister dey help am pick the berries and sell dem for market. Iris pick 30 blueberries, her sister pick 20 cranberries, and her brother fit pick 10 raspberries. If 1/3 of the total berries wey dem fit pick dey spoil and the remaining 1/2 of the fresh berries need to dey kept, how many berries dem go fit sell? <response>: Iris and im brother and sister fit pick total of 30 + 20 + 10 = 60 berries.
The rotten berries wey dem need to throway na (1/3) x 60 = <<(1/3)*60=20>>20.
So, the total number of fresh berries na 60 - 20 = 40.
The berries wey dem need to keep na (1/2) x 40 = <<(1/2)*40=20>>20.
Therefore, the total number of berries wey dem go fit sell na 40 - 20 = 20.

Answer na 20.
