The decimal equivalent of the hexadecimal number F is _________?

• A. 10
• B. 15
• C. 12
• D. 14

Answer: (B)

Hexadecimal uses base 16, so each digit can represent values from 0 to 15. The digits 0–9 have their usual values, and the letters A–F represent 10–15 respectively. The symbol F is the highest single hex digit and corresponds to decimal 15. Therefore, the decimal equivalent of F is 15. The other options reflect the values of the hex digits A (10), C (12), and E (14), not F.
