    The sum of three consecutive integers is 75. Which is the largest among them?

    A)  26                           

    B)         25

    C)  24                                         

    D)  23

    Correct Answer: A

    Solution :

       Let the smallest integer be \[x-1\].    Then the three consecutive integers are \[x-1\], x and \[x+1\].               Their sum = 75                    \[\Rightarrow \] \[(x-1)+x+(x+1)=75\] \[\Rightarrow \] \[x=25\] \[\therefore \]  The largest of the numbers                                 \[x+1=26\]
