You always can use the algebra for this, but an easier manner to reason it out is to think about how far of the $10 means your two varieties are. The $12 coffees is $2 far of the desired price, while the $4 coffees is $6 far of the price of target. That means that to obtain an average price of $10, you must have three times as much of the $12 coffees.

Considering that you have a total weight of 20 books, the only means to do this is to have 15 books of the Arabian and 5 books of the Sumatra.

Better wishes!
