    A) 1684                

    B) 1464

    C) 1784                            

    D) 1844

    E) None of these

    Correct Answer: E

    Solution :

    Let the five consecutive even numbers be
    \[2x,\]\[2x+2,\]\[2x+4,\]\[2x+6,\]\[2x+8.\]
    According to the question,
    \[2x+2x+2+2x+4+2x+6+2x+8=230\]
    \[\Rightarrow \]   \[10x+20=230\]
    \[\Rightarrow \]   \[10x=210\]
    \[\Rightarrow \]   \[x=21\]
    \[\therefore \] Required sum \[=50+{{(42)}^{2}}=1814\]
