  • Question
  • The government wants to devise a toll policy such that the total cost to the commuters per trip is minimized. The policy should also ensure that not more than 70 percent of the total traffic passes through junction B. The cost incurred by the commuter travelling from point S to point T under this policy will be:


  • Options
  • A. $ 7
  • B. $ 9
  • C. $ 10
  • D. $ 13

  • Correct Answer
  • $ 10 

    Explanation

    On the basis of above given question , we can say that
    There must be one other route other than those involving B.
    We must take S - D - C - T as the other route.
    S - B - C - T, if toll at B = 3, total cost = 10
    S - D - C - T, if toll at D and C is 0, total cost is 10.
    Hence ,$ 10 is the least cost.
