Explanation: 

Detailed explanation-1: -However, there is a simple direct method to convert an octal number to binary number. Since there are only 8 symbols (i.e., 0, 1, 2, 3, 4, 5, 6, and 7) in octal representation system and its base (i.e., 8) is equivalent of 23=8. So, you can represent each digit of octal in group of 3 bits in binary number.

Detailed explanation-2: -Count the number of digits present in the given number. Now multiply each digit of the number with 8n-1, when the digit is in the nth position from the right end of the number. Add all the terms after multiplication. The obtained value is the equivalent decimal number.
