composite number means a number that can be formed by multiplying two smaller numbers
3n-1 for n=2, 3n-1=3*2-1=6-1=5
3n-1 for n=10, 3n-1=3*10-1=30-1=29
5 is composite because 2*2.5=5
29 is composite because 5*5.8=29

Adult+student=170 ----(1)
5adult+3student=650 ----(2)
(1)*3; 3adult+3student=510 ----(3)
(2)-(3); 2adult = 140
so adult = 70
then student = 170-70 = 100
