I plant a mixture of blue plants and red plants in the ratio 3:1 in 20,000sqm bed. Red plants require 900cm2 of ground and blue plants 2100cm2 of ground. How many of each plant will I require?
------
# of blue:: 3x
# of red:: x
----
900x + 2100*3x = 20000
900x + 6300x = 20000
7200x = 2000
x = 0.02778
-----
Note:: That is not a realistic answer.
Did you post the problem properly?
