Let x be the fraction of the capacity of each bottle, which is to be filled.grandh01 wrote:Four cups of milk are to be poured
into a 2-cup bottle and a 4-cup bottle.
If each bottle is to be filled to the
same fraction of its capacity, how
many cups of milk should be poured
into the 4-cup bottle?
(A)2/3
(B)7/3
(C)5/2
(D)8/3
(E) 3
Then 2x + 4x = 4
6x = 4
x = 2/3
So, each bottle is to be filled to 2/3 of its capacity.
Hence, the 4-cup bottle should be filled with 4 * (2/3) = [spoiler]8/3[/spoiler] cups.
The correct answer is D.
