35% x (56-44)% x (전체 spectators) = 84. So, 전체 spectators = 2000명. 1% x 2000 = 20명. So, the answer is 20.

If there were 10000 people in total,
men, 10000 x 32/100 = 3200
women, 10000 x 33/100 = 3300
girls, 10000 x 35/100 x 56/100 = 1960
boys, 10000 x 35/100 x 56/100 = 1540.
Then, there are 420 more girls than boys.

If there were 1000 people in total,
men, 1000 x 32/100 = 320
women, 1000 x 33/100 = 330
girls, 1000 x 35/100 x 56/100 = 196
boys, 1000 x 35/100 x 56/100 = 154.
Then, there are 42 more girls than boys.

Now, I get it.
If there are 2000 people in total,
men, 2000 x 32/100 = 320x2
women, 2000 x 33/100 = 330x2
girls, 2000 x 35/100 x 56/100 = 196x2
boys, 2000 x 35/100 x 56/100 = 154x2.
Then, there are 84 (=42x2) more girls than boys.

Therefore, there are 20 (=330x2-320x2) more women than men.

(.35 * .56) * total -> girl
(.35 * .44) * total -> boy
(.35 * .12) * total -> 84
So, total = 2000
.33 * total = 660 -> women
.32 * total = 640 -> men

Answer: 20 more women.
