25% of the people at a party are dancing. 36 of the dancers are men. 3/5 of the non-dancers are women. Given that there are 86 more men who are nor dancing than women who are dancing. How many people were there at the party?

P - 1/4P ==3/4P non-dancers.

3/5*3/4P ==9/20P women non-dancers.

3/4P - 9/20P ==3/10P men non-dancers.

1/4P - 36 == women dancers.

3/10P ==1/4P - 36 + 86, solve for P

P==1000 people at the party.
