Help With SAT Maths Problem (Percentages and Numbers) I usually solve SAT questions easily and fast, but this one got me thinking for several minutes and I cannot seem to find an answer.
Here it is:

In 1995, Diana read $10$ English and $7$ French books. In 1996, she read twice as many French books as English books. If 60% of the books that she read during the 2 years were French, how many English and French books did she read in 1996?
(A) $16$, (B) $26$, (C) $32$, (D) $39$, (E) $48$

Could you please help me by either giving hints or explaining how to solve the problem?
I cannot find, in any way, the number of books of any language she read in 1996. I have tried a lot of operations with percentages, but no results.
Sorry for this question, as I am not very good at Maths.
Thank you.

Total books in 1995 = 17
Let no. Of books studied in 1996 be x
Then no.of French books be 2x
Total books in 2 years = 2x+x+17= 3x+17
60%of total books are French= (3x+17)*6/10
French books in 1995 + French books in 1996 = 2x+7
By above two equations 
2x+7=(3x+17)*6/10 
Solving this we get x value 16
Total books 3x value is 48.
