We need to find the additional pounds

1/3 of a pound means 2/3 is remaining

1/6 of a pound means 5/6 is remaining

1/9 of a pound means 8/9 is remaining

1/18 of a pound means 17/18 is remaining

Remaining will be the additional required = 2/3 + 5/6 + 8/9 +17/18 = 60 / 18

First = (1/3)

Second = (1/6)

Third = (1/9)

Fourth = (1/18)

Total Capacity = 1+1+1+1 = 4 pound

Total Availability of Flour = (1/3) + (1/6) + (1/9) + (1/18) = (6+3+2+1) / 18 = 12/18 = 2/3 pound

Addition Four needed to fill the containers = 4 - (2/3) = 3 1/3 = 10/3 pound

E. 10/3

containers are filled : 1/3+1/6+1/9 +1/18 = 12/18 = 2/3
total capacity = 1+1+1+1 = 4
we can fill 4-2/3 = 10 /3
IMO E
