    Ratio of speeds of β€˜A’ and β€˜B’ is 6:11,

    respectively. If they participate in a 220-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 190 metres Correct Answer Incorrect Answer
    C 120 metres Correct Answer Incorrect Answer
    D 100 metres Correct Answer Incorrect Answer

    Solution

    Let the distance covered by β€˜A’ in the time β€˜B’ covers 220 metres be β€˜x’ metres (x/220) = (6/11) Or, x = 120 So, m = 220– 120 = 100 metres
