Yrrr simply by seeing this what we can think that straight approch to find number of ways for this is not simple so we think in a different manner and what is this....... This is that we first find total number of ways and then subsitute the the number of ways in which girls sits opposite to each so
Total number of ways to sit 6 different person in a round table is (6–1)! =5!=120
And now for sitting of any two girls sits oppsite we take 2 girls and sit in each opposite and then sits remaining 4 in any possible way so the final result for this is 3C2×4!=72
And the reuried answer is 120-72=48
