A. 0.2
B. 0.3
C. 0.4
D. 0.5
E. 0.6
We can plug in the answers, which represent the weight of the tin.
Since the total weight of the tin and the cookies is 2 pounds, the answer choices imply that the uneaten cookies weigh one of the following:
1.8, 1.7, 1.6, 1.5, 1.4.
Since 3/4 of the cookies are eaten, and 1.8, 1.7, 1.5 and 1.4 are not easily divided by 4, only answer choice
C seems viable:
Amount of cookies eaten = (3/4)1.6 = 1.2.
Remaining weight = 2-1.2 = .8.
Success!
The correct answer is
C.
