1. He originally had 21 pesos

2. The farmers were served 27 potatoes. The first farmer ate 9, the 2nd farmer ate 6 and the 3rd farmer ate 4.
   For all to get equal parts, this how the remaining eight should be shared.
   1st farmer = 0 potatoes
   2nd farmer= 3 potatoes
   3rd farmer = 5 potataoes.

I have redeemed and I invite @blessingkasabe and @noha26
