    If the sum of three consecutive even numbers is 234, which is smallest among them?

    A)  \[76\]                                  

    B)                         \[78\]  

    C)                         \[80\]                                  

    D)                         \[68\]

    Correct Answer: A

    Solution :

    Let the three consecutive even numbers be \[2x-2,\text{ }2x\] and\[2x+2\]. We have, \[(2x-2)+2x+(2x+2)=234\] \[\Rightarrow \] \[6x=234\,\,\,\Rightarrow \,\,x=39\] \[\therefore \] The least even number \[=2x-2=2(39)-2=76\]
