Individual 5643

The farmer harvested 300 tons of grain, of which 18 tons were barley, wheat was 250% more than oats, and rye was 40% more than wheat. How many tons of individual grains did he harvest?

Correct answer:

j =  18 t
p =  105 t
o =  30 t
z =  147 t

Step-by-step explanation:

j=18=18 t
r1=100%+250%=1+100250=3.5 r2=100%+40%=1+10040=1.4  j+p+o+z = 300 p = r1 o z = r2 p  j+r1 o+o+r2 p = 300  j+r1 o+o+r2 r1 o=300 18+3.5 o+o+1.4 3.5 o=300  9.4o=282  o=9.4282=30  o=30  p=r1 o=3.5 30=105 t
z=r2 p=1.4 105=147 t
