Partnership :

When two or more than two persons run a business jointly, they are called partners and the deal is known as partnership.

Ratio of Divisions of Gains :

1. When investments of all the partners are for the same time, the gain or loss is distributed among the partners in the ratio of their investments.

Suppose A and B invest x and y respectively for a year in a business, then at the end of the year:
(A's share of profit) : (B's share of profit) = x : y

2. When investments are for different time periods, then equivalent capitals are calculated for a unit of time by taking (capital x number of units of time). Now gain or loss is divided in the ratio of these capitals.

Suppose A invests x for p months and B invests y for q months :

(A's share of profit) : (B's share of profit)= xp : yq.

Working and Sleeping Partners :

A partner who manages the business is known as a working partner and the one who simply invests the money is a sleeping partner.
