the number of the members of a club is more than 50 and less than 80 . when 4 people sit at a table , other people exactly divided to 8 - people groups ( 8 people sit at a table ) or 7 - people groups ( 7 people sit at a table ) . if the members are divided to 9 - people groups , how many people will be left ?
import scipy
n0 = 50.0
n1 = 80.0
n2 = 4.0
n3 = 8.0
n4 = 8.0
n5 = 7.0
n6 = 7.0
n7 = 9.0
t0 = scipy.lcm(int(n3), int(n5))
t1 = n2 + t0
answer = t1 % n7
print(answer)
