Question

How many garlands can be formed using 10 different flowers?

• A. $\frac{9!}{2}$
• B. $\frac{10!}{2}$
• C. $10!$
• D. $10!\times 2!$

Answer 1

The correct option is A $\frac{9!}{2}$

Here anticlockwise and clockwise direction cannot be distinguished, so for n number of flowers, total number of garlands$\to \frac{(n-1)!}{2}=\frac{9!}{2}$
