There are four bus routes from A to B and three bus routes between B and C.A man can travel a round trip in number of ways from A to C via B.If he doesn't want to use a bus route more than once, in how many ways he can make a round trip ?

• From A To B there are 4 choices and from B to C , there are 3 choices.
  From C to B, only 2 choices are left and from B to A, only 3 choices are left.
  
  So total ways = 4*3*2*3 = 72
