The 2 brands are mixed in the ratio 3: 2 =>3x900 + 2x850 = 4400gm which is 5 lits by volume
So, 4 lits mixure is (4x4400)/5 = 3.52 kg

@geneticsgene thanks for the solution!

@unceldolan I think basically the question is about Volume (litres) and weight (grams)
We have the ratio in volume and the answer is asked in weight [how much of 4 litre (of mixture) is in weight]
Also, its my bad coz this question is not a GMAT question. Just found interesting so I posted it. I don't know what system is used in Gmat (probably pounds,miles,etc)
1000gm = 1 kg = 2.2 (approx.) pound

Here's how I did it. My notes from reading the problem were:

1L A = 900 gm
1L B = 850 gm

We are mixing five parts (3 parts A plus 2 parts B, 5 parts total) to get 4L, so 5x = 4 ---> x = 4/5. Each "part" is 4/5 of a liter.

So if we have 3 parts A, we have 900*3*(4/5) = 2160
If we have 2 parts B, we have 850*2*(4/5) = 1360

2160 + 1360 = 3520

Solving for units gives us 3.52

Thanks for the explanation! Didn't see that you meant grmas by "gm"

Now I get it

New ratio = 3:2

For new mixture,

Brand A = 3/5 * 900 = 540

Brand B = 2/5 * 850 = 340

Total = 880 Gms for 1 Litre
So for 4 lts = 880 x 4 = 3520 Gms = 3.52 KG

A.) 3.84
B.) 1.75
C.) 3.52
D.) 2.72
E.) None of these

Given: Brand A has 900 gms of ghee in 1lt and Brand B has 850 gms in 1 Lt
Required: Quantity of ghee in the mixture?

The new mixture is in the ratio of 3:2
Quantity of Brand A in the mixture = 3/5*900 gms = 540 gms
Quantity of Brand B in the mixture = 2/5*850 gms = 340 gms

Hence we have 880 gms for 1 lt of mixture.

Total gms for 4 lts = 880*4 = 3520 gms or 3.52 Kgs

for brand A, 1 liter/900 grams=(3/5)(4) liters/x grams
x=2106 grams
for brand B, 1 liter/850 grams=(2/5)(4) liters/y grams
y=1360 grams
x+y=3520 grams=3.52 kg
