D. 8 / 512
Please scroll down to see the correct answer and solution guide.
Right Answer is: C
SOLUTION
The pattern followed is,
3 / 26 → 3 / (33 – 1); 33 = 27, 27 – 1 = 26;
And,
4 / 65 → 4 / (43 – 1); 43 = 64, 64 – 1 = 63;
Similarly,
11 / 1332 : → 11 / (113 – 1); 113 = 1331, 1331 – 1 = 1330;
And,
9 / ? → 9 / (93 – 1); 93 = 729, 729 – 1 = 728 ≠ 730 or 729.
Therefore, 9 / 730 or 9 / 729 are not correct alternatives.
8 / ? → 8 / (83 – 1); 83 = 512, 512 – 1 = 511 ≠ 512
Therefore, 8 / 512 is not correct alternative.
Hence, “8 / 511” is the correct answer.
