    The HCF and LCM of two numbers are 11 and 385 respectively. If one number lies between 75 and 125, then that number is

    A)  77                   

    B)  88     

    C)  99       

    D)  110

    Correct Answer: A

    Solution :

    [a] We know that product of two numbers \[=HCF\times ~LCM\]of those numbers So, product of numbers \[=11\times 385\] \[=11\times ~75\times ~11\] Since one of them lies between 75 and 125 So this number would be \[=11~\times 7=77\] So the number is 77.
