  • Question
  • If toll tax at all of the toll booths is same and is devised such that the ratio of maximum cost to minimum cost of travel from X to Y is 28 : 19 then which one of the following is the cost of travel from X to Y through toll Both T3?


  • Options
  • A. 320 or 510
  • B. 330 or 560
  • C. 560 or 510
  • D. None of these

  • Correct Answer
  • 560 or 510 

    Explanation

    If toll tax at all of the toll booths is same and let it be k then expense in each path is as follows:
    Path 1: 240 + 3k
    Path 2: 260 + 5k
    Path 3: 260 + 6k
    Path 4: 260 + 5k
    Path 5: 230 + 3k
    So from the given condition On solving we will get k = 50
    Tool booth 3 will come in Path 3 and Path 4.
    So cost incurred is:
    Path 3: 260 + 6k = 260 + 300 = 560
    Path 4: 260 + 5k = 260 + 250 = 510
    Therefore , 560 or 510 is the cost of travel from X to Y through toll Both T3 .
