    The HCF and LCM of two numbers is 16 and 192 respectively if one of the numbers is 64, the other one is

    A) 48                

    B) 24

    C) 72                  

    D) None of these

    Correct Answer: A

    Solution :

    We know that the product of two numbers \[\text{=LCM }\!\!\times\!\!\text{ HCF  x  }\!\!\times\!\!\text{  }64=1932\times 16\] \[x=\frac{192\times 16}{64}=48.\]Thus, other number = 48.
