  • Question
  • If toll tax is devised in such a way that total cost of travel remains same irrespective of the path then what is the minimum cost of travel from X to Y?


  • Options
  • A. 240
  • B. 260
  • C. 310
  • D. None of these

  • Correct Answer
  • 260 

    Explanation

    From the given condition ,
    cost incurred in path 2 is equal to that in path 3 then T3 = 0
    Similarly ,equating cost of path 3 and path 4 T7 = 0
    Equating cost of path 4 and path 5 we will get
    260 + T6 + T8 = 230 + T5
    ? T5 = T6 + T8 + 30
    Equating cost of path 1 and path 2 we will get ,
    240 +T1 = 260 + T2+ T4
    or T1 = T2 + T4 + 20
    For minimum total cost T1 = 20 and T5 = 30 then cost incurred is Rs 260.
    Therefore , the minimum cost of travel from X to Y is Rs 260 .
