• if 1M dance with 3 Womens and
  1W dance with 3 mens then
  this means that 3 mens are dance with 3 womens = 6 peoples ,
  but now in the party 2 mens and 2 womens are present = 4 peoples are now present
  then 6-4 = 2
  add that 2 in the 6members then w will get the total number of people in the party they are = "8"
