Question

plzzz solve this.......​

Answer 1

Answer:

Since there are 9 men and each man dances with 4women (presumably this means each man dances exactly 4 times), there are exactly 36 dance pairs.

Let w be the number of women.

Since each woman dances with 3 men (presumably this means each woman dances exactly 3 times), there are exactly 3w dance pairs.

Thus, 3w=36, so w=12.
