why limit of partners in partnership firm is in company act

In response to your query,

A company is called a firm when it is a partnership of two or more persons. An organisation is an organized group of people with a particular purpose, such as a business or government department. Corporation is a large company or group of companies authorized to act as a single entity and recognized as such in law.

As a firm is also a company only with multiple partners therefore the limit in partnership in firms is mentioned in the Companies Act.
