In the venn diagram, 69 farms only grow potatoes or only sugar beet.
4/5 of these 60 farms grow only potatoes.

You got a good start !

For the box that is in the Venn

  you are told     48 + x  =  3 (12+x)      

                           48 + x = 36 + 3x

                             12 = 2x

                               x = 6       for the box in the Venn   

 

THEN add up all of the numbers in the Venn       these are the farms that grow beets and /or potatoes    subtract this number from 100 to find the number for the lower left corner.....the number that do NOT grow potatoes or beets.
