Solution
The universal set is the set that contains all the other sets under consideration.
Here:
- P = Residents in Pune
- I = Residents in Indore
- H = Residents in Maharashtra
- M = Residents in Madhya Pradesh
- B = Residents in India
Since all residents of Pune, Maharashtra, Indore, and Madhya Pradesh are residents of India, set B contains all the other sets.
