Answer: (C) 23
Answer: (C) 23
Answer: (C) 23
X + (X+2) + (X+4) + (X+6) + (X+8) = 95
=> 5X + 20 = 95
=> 5X = 95-20
=> 5X = 75
=> X = 15
Hence (X+8) = 15+8 = 23
X + (X+2) + (X+4) + (X+6) + (X+8) = 95 => 5X + 20 = 95 => 5X = 95-20 => 5X = 75 => X = 15 Hence (X+8) = 15+8 = 23
X + (X+2) + (X+4) + (X+6) + (X+8) = 95 => 5X + 20 = 95 => 5X = 95-20 => 5X = 75 => X = 15 Hence (X+8) = 15+8 = 23

The options listed are related to character encoding schemes, which are methods of representing text characters in computers. ASCII (American Standard Code for Information Interchange) is a widely used character encoding standard that represents text in computers, telecommunications equipment, and other devices. BCD (Binary-Coded Decimal) is a method of encoding decimal numbers where each decimal digit is represented by its own binary sequence. While primarily for numbers, it's a form of data representation or "code." EBCDIC (Extended Binary Coded Decimal Interchange Code) is another character encoding standard, primarily used on IBM mainframe operating systems.
