    A box had some pens in it. When the pens are distributed equally to \[18\] children, none remained but while distributing to \[19\] children, \[5\] children got \[1\] pen less than the others. How many pens were there in the box?

    A)  \[70\]                           

    B)                     \[76\]                           

    C)                     \[90\]                           

    D)                     \[85\]               

    Correct Answer: C

    Solution :

    According to the problem, the number of pens is exactly divisible by\[18\]. Also, the number is 5 less to be divisible by\[19\]. \[\therefore \]The required number is\[19\times 5-5\] \[=95-5=90\], which is exactly divisible by\[18\]
