Let the solution contains v liters of vinegar.
therfore oil = 4 (v) [from prompt ]
and w = 2(o) [from prompt]
Statement 1: oil = 5 liters
therfore water = 10 liters and v = 5/4 = 1.25 liters hence can calculate the value of x = 1.25 + 5 + 10 = 16.25 liters.
Statement 2 : solution contain 60 % water , 40 % vinegar and oil .
but we do not have any concrete value for any of the one variables hence cannot find the value of x.
