Q: The number 93248x6 are divisible by 11. Then digit x is equal to.
  • A. 5
  • B. 2
  • C. 8
  • D. 7
Correct Answer: Option D - Divisibility rule of 11–In a given number if the difference of sum of all digit even place and placed at odd place is zero or multiple of 11, then that number will also be divisible by 11. (9+2+8+6)–(3+4+x) 25 – (7+x) = 11 18–x = 11 x = 18 – 11 Hence, x = 7
