    Question

    Two trains β€˜A’ and β€˜B’ started from station

    β€˜P’ and β€˜Q’ towards station β€˜Q’ and β€˜P’ respectively at the same time. When they met after 15 hours, train β€˜B’ has travelled 150 km more than train β€˜A’. Find the distance travelled by train β€˜A’ in 10 hours if distance between both stations is 555 km.
    A 135 km Correct Answer Incorrect Answer
    B 119 km Correct Answer Incorrect Answer
    C 115 km Correct Answer Incorrect Answer
    D 105 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let distance travelled by train β€˜A’ at the time of meet = β€˜x’ km So, distance travelled by train β€˜B’ at the time of meet = β€˜x + 150’ km According to question; x + x + 150 = 555 => 2x = 405 => x = 202.5 Distance travelled by train β€˜A’ in 15 hours = 202.5 km Speed of train β€˜A’ = 202.5/15 = 13.5 km/h Distance travelled by train β€˜A’ in 10 hours = 10 Γ— 13.5 = 135 km
