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 136, while 3 / 4 of all his trees are pure fuji. how many of his trees are pure gala?  Choose the correct choice from the following choices:
A) 24
B) 33
C) 55
D) 77
E) 88

subtract(divide(136, add(divide(10, const_100), divide(3, 4))), 136)
let f = pure fuji , g = pure gala and c - cross pollinated . c = 10 % of x where x is total trees . c = . 1 x also 3 x / 4 = f and c + f = 136 = > . 1 x + 3 / 4 x = 136 = > x = 160 160 - 136 = pure gala = 24 . a
