    Question

    Ratio of speeds of β€˜A’ and β€˜B’ is 5:7,

    respectively. If they participate in a 350-metre race and β€˜B’ gives β€˜A’, a head start of β€˜m’ metres, then they finish the race at the same time. Find the value of β€˜m’.
    A 110 metres Correct Answer Incorrect Answer
    B 120 metres Correct Answer Incorrect Answer
    C 100 metres Correct Answer Incorrect Answer
    D 130 metres Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the distance covered by β€˜A’ in the time β€˜B’ covers 350 metres be β€˜x’ metres (x/350) = (5/7) Or, x = 250 So, m = 350 – 250 = 100 metres
