The equivalent hexadecimal notation for octal number 2550276 is :
ADOBE
Convert octal to binary by writing each octal digit as 3 bits, then regroup the bits in 4s from the right to read the hexadecimal digits.
\(2550276_{8} = 010\ 101\ 101\ 000\ 010\ 111\ 110_{2}\)
Regrouping: \(1010\ 1101\ 0000\ 1011\ 1110_{2}\)
\(= A\ D\ 0\ B\ E = AD0BE_{16}\)
The letter O in the printed choice stands for the digit 0, so the value reads as ADOBE; FADED, AEOBE and ACABE give different bit patterns.
Check: \(AD0BE_{16} = 708798_{10}\) and \(2550276_{8} = 708798_{10}\).
Hence, ADOBE.
