Answer
Find out the how many women were there .
To prove
Let us assume that the x is the scalar multiple of men and women.
As given
The ratio of men to women was 3 : 2.
Than
The total number of men = 3x
The total number of women = 2x
As given
If 120 men used the gym.
thus
120 = 3x
x = 40
The total number of women = 2 × 40
= 80
Therefore 80 women were there in the gym .

EXPLANATION
A basic sine curve has equation in the form:
Where 'a' is the amplitude.
In this case a=2 because the amplitude is 2.
For a transformed sine function, the general equation is:
where a=2 is still the amplitude
This is also a sine function with an amplitude of 2.
