Dima and Sergey were picking berries from a raspberry bush that had 900 berries. Sergey alternated his actions: he would put one berry in the basket, then eat the next one. Dima also alternated his actions: he would put two berries in the basket, then eat the next one. It is known that Sergey picks berries twice as fast as Dima.
