Answer 1

Concept:

n different objects are arranged around a circle, then the number of arrangements is (n – 1)!

Calculation:

First, arrange 5 men at the round table in (5 - 1)! ways = 4!

Now, women sit on the 5 spaces generated between the men

This can be done in ⁵P₃ ways

Hence the total number of ways is = 4! × 5P3
