    Which of these numbers has the least value?

    A)  \[CDCX\]                     

    B)                     \[CDXL\]                     

    C)                     \[DCLX\]                     

    D)                     \[DCXL\]                     

    Correct Answer: B

    Solution :

    \[CDCX=(500-100)+100+10\] \[=400+110=510\] \[CDXL=(500-100)+(50-10)=440\] \[DCLX=500+100+50+10=660\] \[DCXL=500+100+(50\text{ }-10)=640\] \[\therefore \]\[CDXL\]has the least value.
