Dima and Serezha were picking berries from a raspberry bush that had 450 berries. Serezha alternated his actions: he would put one berry in the basket and eat the next one. Dima also alternated: he would put two berries in the basket and eat the next one. It is known that Serezha picks berries twice as fast as Dima.
