    Two numbers are in the ratio of 15 : 11. If their HCF is 13, then numbers will be

    A) 195 and 143

    B) 190 and 140

    C) 185 and 163

    D) 185 and 143

    Correct Answer: A

    Solution :

    Let the required numbers be 15x and 11x. Then, their HCF is x.
    So, \[x=13\]
     \[\therefore\]  The numbers are \[15\times 13\] and \[11\times 13\]  
    i.e. 195 and 143.
