    Question

    Ratio of speeds of тАШAтАЩ and тАШBтАЩ is 11:13,

    respectively. If they participate in a 130-metre race and тАШBтАЩ gives тАШAтАЩ, a head start of тАШmтАЩ metres, then they finish the race at the same time. Find the value of тАШmтАЩ.

    D 12 metres Correct Answer Incorrect Answer

    Solution

    Let the distance covered by тАШAтАЩ in the time тАШBтАЩ covers 130 metres be тАШxтАЩ metres (x/130) = (11/13) Or, x = 110 So, m = 130 тАУ 110 = 20 metres
