A certain 4-liter solution of vinegar and water consists of x liters of vinegar and y liters of water. How many liters of vinegar does the solution contain?

(1) x/4 = 3/8
(2) y/4 = 5/8



Show SpoilerMy concern
Can someone help to solve this using allegations and mixtures?


NOTE: I know this can be solved using finding values of x and y too... but i am looking for allegations method out of curiosity..

This is not an allegations question. allegations would be used in something like this:
you have a solution which is 10% vinegar and 90% water. The new solution needs to be 85% water. How much vinegar should be added. (not a very good question but something like this).

Let me give you a real question which you may want to solve using allegation:

A certain quantity of 40% solution is replaced with 25% solution such that the new concentration is 35%. What is the fraction of the solution that was replaced?
(A) 1/4
(B) 1/3
(C) 1/2
(D) 2/3
(E) ¾

We don't need allegation for solve this question
Given: x + y = 4

(1) x = 1.5
Sufficient.

(2) y = 2.5
hence x = 4 - 2.5 =1.5
Sufficient

Hence D

This is not an allegation or mixture problem.

This is a simple equation problem

x+y=4

1. Gives value of x
Suff
2. Gives value of y
Suff
Hence D

Seems a 500 level ques.

1. X = 3/2 Suff.
2. Y = 5/2 and X + Y = 4 (given) Suff.

­For 2nd option to be correct add (only)in the question like this the solution (only) contains vinegar and waters, beacause 2nd option states about the water we dont know if there is another portion of something in that solution
