  • Options

  • C. 1, 5, 4, 2
  • D. 0, 5, 2, 3

  • Correct Answer

    Explanation

    From the given diagram ,
    Let the toll charged at junctions A, B, C and D be a, b, c and d respectively.
    Then 1st we will list down all the routes and corresponding cost of travel.
    Since the cost of travel including toll on routes S-A-T, S-B-C-T, S-B-A-T and S-D-C-T is the same. And D-T has no traffic due to high toll charge at D.
    From the last solutions we will get b = 5, 14 + a = 7 + b + c = 12 + c, or a + 2 = c 7 + b + c = 10 + c + d = 12 + c or d = 2, hence the result is B = 5, d = 2 and c-a = 2 that is satisfied by option (E).
