```							The answer is 10!-(6!5!). The total number of ways of arranging 5 boys and five girls is 10!. Now we consider the total number of ways of seating them such that the 5 girls are always together and we subtract this from 10!.For that, Let us consider the 5 girls as 1 unit. Therefore total number of ways of seating 5 boys and the 1 unit =6!5! ( Multiplying by 5! as the five girls can be arranged amongst themselves in 5! ways), Thus, the answer is 10!-(6!5!)
