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 153 , while 3 / 4 of all his trees are pure fuji . how many of his trees are pure gala ?
n0 = 10.0
n1 = 153.0
n2 = 3.0
n3 = 4.0
t0 = n0 / 100.0
t1 = n2 / n3
t2 = t0 + t1
t3 = n1 / t2
answer = t3 - n1
