Let \(m\) denotes the number of ways in which 5 boys and 5 girls can be arranged in a line alternately and n denotes the number of ways in which 5 boys and 5 girls can be arranged in a circle so that no two boys are together. If \(m=k n\), then the value of \(k\) is
- A 30
- B 5
- C 6
- D 10
Answer & Solution
Correct Answer
(D) 10
