A unit recently organized a fitness activity, which was divided into a hiking group and a swimming group, with each employee participating in at most one group. Among the employees who participated in the activity, 42.5% were young people, 47.5% were middle-aged, and 10% were elderly. The employees in the hiking group accounted for $\frac{1}{4}$ of the total number of participants, and in this group, 50% were young people, 40% were middle-aged, and 10% were elderly. To understand the satisfaction levels of employees of different age groups in each group towards this activity, a stratified sampling method was used to draw a sample of 200 from all employees who participated in the activity. Determine:  
(Ⅰ) The proportion of young people, middle-aged people, and elderly people in the swimming group;  
(Ⅱ) The number of young people, middle-aged people, and elderly people that should be drawn from the swimming group.
