well, if it is simply asking for how much BEANS, then its quite easy, just divide 396 by two because the mixture uses 1 kilogram of each. They tried to trick you, I had to look at it for a while.

Suppose the cost of Brazillian and Turkish coffee was $10.4 and $17 per kg respectively.
What would be the weight of each coffee to make a 396 kg mixture?

Let B and T be the weight of the cost of Brazillian and Turkish coffee per kg respectively.
Solve the following equations for B and T:

{ 10 B + 12 T = 11 ( B + T ), B + T = 396}

Both B and T = 198 kg.
