(B) 24

Let total number of men=x and women=y, then
Dancing men=(3/4)x and women=(4/5)y
As dancing men= Dancing women => (3/4)x =(4/5)y or 15x=16y
This condition satisfies for x=16 & y=15 where it is given, x+y is less than equal to 50.
So total people dancing=(3/4)x + (4/5)y =(3/4)*16 + (4/5)*15= 24
