Let 6x,5x,2x and 2x represent the no of liters of red ink, blue ink, green ink, and yellow ink respectively as per 1st statement we have

6x=5x+2

x=2

No of liters of green ink=2x=4 liters. Sufficient.

Statement II is sufficient: The batch consists of 30 liters of color X ink.

6x+5x+2x+2x=30

15x=30

x=2

No of liters of green ink=2x=4 liters. Sufficient.
