    Stamps in an album can be arranged as \[12\] per page or \[18\] per page exactly. What is the greatest number of stamps one can have if they are fewer than\[500\]?

    A)  \[468\]                         

    B)                     \[540\]             

    C)                     \[504\]                         

    D)                     \[432\]

    Correct Answer: A

    Solution :

    \[L.C.M.\]of\[12\]and\[18\]is\[36\]. \[\therefore \]The required number of stamps is the largest multiple of\[36\], less than\[500\]. \[500\div 36=13\,\,R\,\,32\]as \[36\times 13=468\]and\[36\times 14=504\]. Thus, the required number of stamps \[=468\]
