Vinegar and Water

by harsh.champ » Wed Feb 17, 2010 5:42 am
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
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

(1) x/4 = 3/8
(2) y/4 = 5/8
X+Y=4
So we have to calculate X and Y
st.1: we get X hence Y
st.2: we get Y hence X

Ans D.

IMO D because you can solve each equation for the variable nad then plug into the original question
My goal is to make MBA applicants take onus over their process.

The OA is D.
Important pt. to note:-As x an y are complimentary,so in such questions knowing one variable is sufficient to solve the question.

In haste ,one can write insufficient in both the statements alone as only one variable is given.
It is very important thereby to read the question carefully.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)
