  • Question
  • If the government wants to ensure that the traffic at S gets evenly distributed along streets from S to A, from S to B, and from S to D, then a feasible set of toll charged (in rupees) at junctions A, B, C, and D respectively to achieve this goal is:


  • Options
  • A. 0, 5, 4, 1
  • B. 0, 5, 2, 2
  • C. 1, 5, 3, 3
  • D. 1, 5, 3, 2

  • Correct Answer
  • 0, 5, 4, 1 

    Explanation

    According to question ,
    If all the five routes have the same cost, then there will be an equal flow in all the five routes, i.e. 20% in each route.
    But then the percentage of traffic in S - A = 20% (Only one route involving S - A)
    S - B = 40% (As there are two routes involving S - B)
    S - D = 40% (As there are two routes involving S - D)
    But here the given condition that traffic in S-A is equal to that in S - B, which in turn is equal to S - D is not satisfied.
    Of the routes, that can be used the number of routes involving S - A must be the same as S - B, which in turn is same as that as S - D.
    That is possible only when we block the junction C and that can be done by taking higher toll charge at C to achieve this goal c > 3.
    Hence , required answer will be option A .
