Question

• A. $4^5$
• B. $2^5$
• C. $3^4$
• D. $7^4$

Answer 1

The correct option is A $4^5$

The first ring can be worn in any of the $4$ fingers. So they are $4$ ways of wearing it.

Similarly, each one of the other rings can be worn in $4$ ways.

Hence, the required number of ways $=4\times 4\times 4\times 4\times 4=4^5$.
