To determine the number of men paid weekly, follow these steps:

1. Determine the Number of Women Employed:

The company employs 100 people, 65 of whom are men. Therefore, the number of women is:
$$\text{Number of women}=100-65=35$$

2. Determine the Total Number of People Paid Weekly:

60 people are paid weekly, and this includes all the women.

3. Calculate the Number of Men Paid Weekly:

Since all 35 women are paid weekly, the number of men paid weekly is:
$$\text{Number of men paid weekly}=\text{Total people paid weekly}-\text{Number of women}$$
$$\text{Number of men paid weekly}=60-35=25$$

The number of men that are paid weekly is 25.

The correct answer is C. 25.
