This video explains how to use Ratios to solve problems in this topic. This is a branch of Applied Mathematics. Also taught in CBSE Class 12.

A Partnership is when 2 or more partners invest equal amounts of money for different time periods or unequal amounts for the same time period.

You are introduced to the two types of partnerships, namely simple and compound.You are also given the formulas for each partner's share in the profit in both partnerships.
