    A)  1365    

    B)  2035

    C)  1935                           

    D)  1585

    E)  None of these

    Correct Answer: A

    Solution :

     Let the consecutive odd numbers be x, x + 2, x + 4, x + 6 and x + 8 respectively,      According to the question, \[x+x+2+x+4+x+6+x+8\] \[=\text{ }5\times 37\] \[\Rightarrow 5x+20=185\] \[\Rightarrow 5x=185-20=165\] \[\Rightarrow x=\frac{165}{5}=33\] \[\therefore \,\,A=33,\] \[B=33+2=35\] \[D=x+6=33+6=39\] \[\therefore B\times D=35\times 39=1365\]
