  1. OA E
    resultant outcome of this eqn is
    23times 9 followed by 440 i.e.
    9999999....(23times)...440
    sum of this number is 8 not divisible by 3..Hence OA E
    11,8,5,4 divisible

  2. Yep, good job Bhushan, answer is E. And also, if you are in a hurry you can quickly eliminate B, C, and D, because the number is gonna end in a zero, so it will be divisible by 5 and will have the two 2s and three 2s to make it divisible by 8.
