Two farmersfoundthat the Yieldfrom their paddyplantswas not the same,even thoughthey used the same soil,same fertilizerand same seedlings.FarmerA plantedmore paddy plantsthen farmerB, but the yield from FarmerB is more than FarmerA. Dua orang peladang mendapati hasil keluaran padi mereka tidak sama, walaupun mereka menglgunakan tanah yang sama , baia yang sama dan benih yang sama PeladangA menanam lebihbanyak pokok padi berbandingPeladangB tetapi hasildari PeladangB adalahlebih daripadaPeladangA.
