Concept: The question tests on the basics of Counting

Solution:

The number of permutations of n things in a circle, when clockwise and anti clockwise are considered to be different is = (n - 1)!

Let us consider the 3 women as 1 unit. So we have 6 units (5 boys + 1 unit of 3 women) to arrange.

External arrangement = (6 - 1)! = 5! = 120

Internal arrangement of the women = 3! = 6

Total number of ways = 120 * 6 = 720
