**Solution**

• The 7’s complement = 5264.

• Therefore, the octal number = (2513)8.

• The binary equivalent = (010 101 001 011)2 = (10101001011)2.

• Also, (10101001011)2 = (101 0100 1011)2 = (0101 0100 1011)2 = (54B)16.

• Therefore, the hex equivalent of (2513)8 = (54B)16 and the binary equivalent of (2513)8 =(10101001011)2.
