(b) (6612)8

(c) (4532)8

(d) (6745)8

This question was addressed to me during an interview for a job.

I'd like to ask this question from Number System in chapter Number System and Codes of Digital Circuits

Answer 1

Correct option is (b) (6612)8

For explanation: The binary equivalent is segregated into groups of 3 bits, starting from left. And then for each group, the respective digit is written. Thus, the octal equivalent is obtained.

(110110001010)2 = (6612)8.
