    Question

    Two trains started from stations ‘A’ and ‘B’ at

    same time and started travelling towards each other at speeds of 40 km/hr and 30 km/hr, respectively. At the time of their meeting, the faster train has travelled 100 km more than the slower train. Find the distance between the stations ‘A and ‘B’.
    A 720 km Correct Answer Incorrect Answer
    B 600 km Correct Answer Incorrect Answer
    C 700 km Correct Answer Incorrect Answer
    D 750 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the distance travelled by slower train be ‘x’ km So, distance travelled by faster train = ‘x + 100’ km ATQ, (x/30) = {(x + 100)/40} Or, 40x = 30x + 3000 Or, 10x = 3000 So, x = 300 Total distance between station ‘A’ and station ‘B’ = (300 + 300 + 100) = 700 km
