The Mango Sellers

A village has only 50 people in it. A mango farmer named X arrived from another village and brought 100 mangoes with him and sold each villager 2 mangoes to each villager for two coppers. The next day when the same farmer X arrived with 100 mangoes with him another farmer Y had also arrived and started to sell 100 mangoes at 2 mangoes for a copper. So, farmer X also sold 2 mangoes for a copper and the 50 villagers had 4 mangoes each for two coppers; double from what they had the previous day for the same price. The next day the competition increased and another farmer, farmer Z also arrived with a 100 mangoes. What will farmer X and Y do? How much will each farmer earn?
