in a class , there are 18 boys who are over 160 cm tall . if these constitute 3 - fourths of the boys and the total number of boys is two - thirds of the total number of students in the class , what is the number of girls in the class ?
n0 = 18.0
n1 = 160.0
n2 = 3.0
t0 = n2 / 4.0
t1 = 2.0 / n2
t2 = n0 / t0
t3 = t2 / t1
answer = t3 - t2
