Which of the following is fifth to the right of the twelth digit from the right end of the below arrangement?

1 8 5 9 4 7 1 2 5 8 3 6 5 9 2 7 6 4 5 2 9 2 6 4 1 2 3 5 1 4 2 8 3

  • A.3
  • B.1
  • C.2
  • D.7

Answer: A

Correct answer: 3

The arrangement holds 33 digits, so the twelfth from the right end is the \( 33-12+1 = 22 \)nd from the left, which is 2. Counting five places to its right lands on the 27th digit, 3.
