    If 738A6A is divisible by 11, then the value of A is

    A) 6

    B) 3

    C) 9

    D) 1

    Correct Answer: C

    Solution :

    [c] Since, 738A6A is divisible by 11, therefore Sum of odd places - Sum of even places = Either multiple of 11 or 0 \[(7+8+6)-(3+A+A)=\] Either multiple of 11 or 0 \[\Rightarrow \]   \[21-2A+3=\]Either multiple of 11 or 0 \[\Rightarrow \]   \[18-2A=0\] (\[\because \]It can't be a multiple of 11) \[\Rightarrow \]   \[2A=18\]\[\Rightarrow \]\[A=9\]
