Question 66

Find the number of ways in which ten different flowers can be strung together to make a garland in such a way that three particular flowers are always together?

Now total number of flowers is '8' and these flowers can be arranged in 8! ways. And

Three particular flowers are arranged in 3! ways.

Total number of ways = 8! x 3! = 241920
