alleryStart learning →A 2 L mixture contains 0.4 L juice. Add x L water; volumes add. For juice to be 1/10 of the new volume, what is x?
A2
B4
C1.8
D0.2
Answer & Solution
Correct answer: A. 2
The juice amount remains 0.4 L while the total volume becomes 2+x L. The condition is 0.4=(2+x)/10, so 4=2+x and x=2 L.
