Hi guys, got this one in the gmat prep and it thoroughly confused me..

According to directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice. How many 12-ounce cans of the concentrate are require to prepare 200 6-ounce servings of orange juice?

a) 25

b) 34

c) 50

d) 67

e) 100

thoughts?

One easy way to get this done.

Conc:Water = 1:3

So, Conc. = 1\4 of Juice

We need to know about 12ounces of conc. i.e. 12x.

12x = 1\4 of 100. (200 6-ounce servings = 100 12-ounce servings)

12x = 25.

We need to find the value of 12x.
