Homework Statement
I got following Question from a book:
I am doing it using a different method but my answer is wrong. Can somebody please guide me, what is the problem with it??
The question is:In 1999, Diana read 10 English books and 7 French books. In 2000, she read twice as many French books as English books. If 60% of the books that she read during the two years were French, how many books did she read in 2000?
Homework Equations
Linear equation in single variable based problem
The Attempt at a Solution
1999: E(10), F(7) = 17
2000: E(x), F(2x)
Two years total books = 10 + 7 + x + 2x
1.666x /*60 % */ + 2.5x /* 40 */ = 17 + 3x
4.166 - 3x = 17
X = 14.579
2x = 29
Total = 15 + 29 = 44 (wrong answer)
Some body please guide me.
