  • Question
  • The auto-rickshaw fare consists of a fixed charge together with the charge for the distance covered. For a journey of 10 km, the charge paid is ?85 and for a journey of 15 km, the charge paid is ?120. The fare for a journey of 25 km will be


  • Options
  • A. ?175
  • B. ?190
  • C. ?180
  • D. ?225

  • Correct Answer
  • ?190 

    Explanation

    Let use assume the fixed charge = ? a
    and charge for 1 km is ? = b
    According to question,
    for 10 KM journey charge paid = 85
    a + 10 x b = 85
    a + 10b = 85 .........................(1)
    for 15 KM journey charge paid = 120
    a + 15b = 120.........................(2)
    Subtract the equation (1) from equation (2). we will get,
    a + 15b - a - 10b = 120 - 85
    5b = 35
    b = 7
    Put the value of b in equation (1). we will get
    a + 10 x 7 = 85
    a = 85 - 70
    a = 15
    Charges for 25 km = a + 25 x b
    Put the value of a and b in above equation.
    Charges for 25 km =15 + 25 x 7 = 15 + 175 = 190
    Charges for 25 km =?190
