Partnership
Overview
Partnership is a fundamental arithmetic topic in IBPS PO Prelims that tests your ability to divide profits (or losses) among business partners based on their capital contributions and the duration of investment. This topic directly builds on your understanding of ratios and proportions, making it a natural extension of basic arithmetic concepts.
In IBPS PO Prelims, partnership questions typically appear as 1-2 questions in the Quantitative Aptitude section. They range from straightforward profit-sharing calculations to more complex scenarios involving multiple partners, changing capitals, and working vs. sleeping partners. Mastering this topic gives you quick, reliable marks because the underlying logic remains consistent across all question variations.
Students must understand two core principles: profit shares are proportional to capital invested, and when time varies, you must calculate the "capital-time product" for each partner before finding ratios.
Key Concepts
- **Simple Partnership**: All partners invest for the same duration. Profit ratio equals the ratio of their capitals directly.
- **Compound Partnership**: Partners invest for different time periods. Profit ratio equals the ratio of (Capital × Time) for each partner.
- **Capital-Time Product**: The effective investment of a partner = Capital × Number of months invested. This is the basis for all compound partnership calculations.
- **Working Partner vs. Sleeping Partner**: A working partner manages the business and may receive a salary or extra share before profit distribution. A sleeping partner only contributes capital.
- **Changing Capital**: When a partner adds or withdraws capital mid-year, calculate separate capital-time products for each period and sum them.
- **Profit Distribution Formula**: Partner A's share = (A's capital-time product ÷ Total capital-time product) × Total Profit.
- **Loss Sharing**: Losses are shared in the same ratio as profits unless specifically stated otherwise in the partnership agreement.
Formulas / Key Facts
**Simple Partnership (same time period):** Profit Ratio = Capital of A : Capital of B : Capital of C
**Compound Partnership (different time periods):** Profit Ratio = (C₁ × T₁) : (C₂ × T₂) : (C₃ × T₃) Where C = Capital invested, T = Time in months
**Individual Share Calculation:** A's Profit = (A's contribution ÷ Total contribution) × Total Profit
**When capital changes during the year:** Effective Capital = (C₁ × T₁) + (C₂ × T₂) Where C₁ is initial capital for T₁ months, C₂ is changed capital for T₂ months
