(The idea behind the test is to revise questions as we find issues with them or cleaner solutions). That's what happened - please download the latest PDF.

Last part of the question asks for the price of 1 KG of Walnut, not the price of the walnut in the mixture... I tried in this way .4 kg of X .6 kg of Y total 1 kg. Now increase X by 50%...now it becomes .6 , which means .2 increase costs$1 more. Hence, .4 Kg cost of X will be $2. Remaining$ 5 is for .6 Kg of Y. So for 1 kg of Y will be $8.34 (5/ 0.6) Do you think I am in a right direction ?

Question does ask for the price of 1 KG of Walnut, not the price of the walnut in the mixture. A0 = C + W = 7 A1 = 1.5C + W = 8 => C=2 => W=5$5 is the price of walnuts in the mixture, not the price of 1 KG of walnuts.

We don't have the value of Y => can't know how many KG of walnuts the mixture has => can't calculate the price of 1 KG of walnuts.

I am afraid this question has more than one correct answer unless you provide in the statement one of the percentages of the mixture either the chestnuts content or the walnuts content.

KUDOS
I did not see any confusion here. TIGER's solution is absolutely rite.

For those guys who were confused, I believe it is helpful to always keep in mind that:
1) the sum of weights of 2 nuts is always 1 kilo no matter how the mixture changes, which implies:
2) when chestnut in the mixture is increased by 50%, do remember that the weight of walnut should be decreased by a certain percetage (generally NOT by 50% unless the original mixture is 50% vs. 50%) to keep the sum of 1 kilo (implication 1)

Did I make it clear?

I don't think this isn't a 650 level question...
