Question

The number of ways in which $6$ rings of different type can be had in $4$ fingers is

• A. $4096$
• B. $4000$
• C. $4098$
• D. None of these

Answer 1

The correct option is A $4096$

The first thing can be worn in any of the 4 fingers. So, there are 4 ways of wearing it. Similarly, each one of the other rings may be worn in 4 ways
$\therefore$ total number of ways $=4^6=4096$
