A farmer has an apple orchard consisting of Fuji and Gala apple trees. Due to high winds this year 10% of his trees cross pollinated. The number of his trees that are pure Fuji plus the cross-pollinated ones totals 238, while 3/4 of all his trees are pure Fuji. How many of his trees are pure Gala?
Choose the correct answer.
A) 22 B) 33 C) 55 D) 42 E) 88
Let f = pure fuji , g = pure gala and c - cross pollinated.   c = 10% of x where x is total trees.   c = .1x   also 3x/4 = f and c+f = 238 =&gt; .1x + 3/4x = 238 =&gt; x = 280   280 - 238 = pure gala = 42.   Answer 42
