The farmer

The farmer harvested 840 tons of grain in 2006, which was 44% less than in 2005, and one-fifth more than in 2004. How many tons of grain harvested in years 2005 and 2004?

Result

x =  700 t (2004)
y =  1500 t (2005)

Solution:

Solution in text x =

840 = (1-44/100)*y
840 = (1+1/5)*x

56y = 84000
6x = 4200

x = 700
y = 1500
