Partnership Notes & Questions
When two or more people invest their money in a business, persons are called Partners, their relationship is Partnership and money is Capital.
- If they invest money for the same time, it is called a Simple partnership.
- If they invest money for a different time, it is called a Compound partnership.
Partnership Problems
Profit is directly proportional to Time and Investments.
Profit ∝ Time Profit ∝ Investments
Profit ∝ (Time × Investments)
Example 1:
Three partners A, B, and C invest Rs.1500, Rs.1200, and Rs.1800 respectively in a company. How should they divide a profit of Rs.900?
Solution: Given, there is no time given, we can say profit is proportional to investment.
Ratio of profit = ratio of investment
Profit ratio of A:B:C = 1500:1200:1800 =5:4:6
so, total profit is 5+4+6 = 15 i.e. equal to 900
profit of A = (5/15)× 900 = 300
profit of B = (4/15)× 900 = 240
profit of C = (6/15)× 900 = 360
Example 2:
In a company, A invested Rs.1500 for 4 months and B invested Rs.1200 for 6 months and C invested Rs.3600 for 2 months. If a company has a profit of Rs.680. What will be the share of A, B, and C?
Solution:
Ratio of profit A:B:C = (1500 × 4):(1200 × 6):(3600 × 2)
= 60:72:72
= 5:6:6
total profit is 5+6+6 = 17 i.e. equal to 680.
we can say, 17 = 680
1 = 40
profit of A is 5, so 5× 40 = 200
profit of B is 6, so 6× 40 = 240
profit of C is 6, so 6 × 40 = 240
Note: Read questions carefully. If we can calculate capital invested and the time for which capital is invested. We can easily calculate shares in profit.
Example 3:
A and B enter into a partnership with Rs.50000 and Rs.75000 respectively in a company for a year. After 7 months, C gets into a partnership with them with Rs.30000 and A withdraws his contribution after 9 months. How would they share their profit of Rs.2600 at the end of the year?
Solution: A, B, and C do business for 1 year but, A contributed Rs.50000 for 9 months, B contributed 75000 for 12 months and C invested Rs.30000 for 5 months, not for 7 months.
So the ratio of profit A:B:C = 50×9: 75×12: 30×5
= 15 : 30 : 5
Hence total profit is (15+30+5) = 50 which is equal to 2600
So share of A = (15/50)× 2600 = 780
share of B = (30/50)× 2600 = 1560
share of C = (5/50) × 2600 = 260
Example 4:
A, B and C started a company in which A invested (1/3)^{rd} of the capital for (1/4)^{th} of the time, B invested (1/2)^{nd} of the capital for (1/6)th of the time and C invested the remaining capital for the whole of the time. If the profit at the end of the year is Rs.1200. How would they share it?
Solution: A invested (1/3)^{rd }of the capital and B invested (1/2)^{nd} of the capital
So, remaining capital invested by C = 1-((1/3)+(1/2)) = 1/6
The ratio of profit A: B:C = (1/3)× (1/4): (1/2)× (1/6): (1/6)× 1
= (1/12):(1/12):(1/6)
= 1 : 1 : 2
A’s share = (1/4)× 1200 = 300
B’s share = (1/4)× 1200 = 300
C’s share = (1/2)× 1200 = 600
Example 5:
A and B rent a field for 11 months. A puts 100 bags for 9 months. How many bags can be put by B for 3 months if the ratio of their rent is 2:3?
Solution: Let B puts X bags.
the ratio of rent of A: B is 2: 3
so, (100×9) : (X × 3 ) = 2 : 3
X = 450 bags
Example 6:
If A and B entered into a partnership and invested their capital in the ratio of 19:15. At the end of 19 months, B withdraws his capital. If they share profit in the ratio of 3:2, then for how many months A invested his ratio?
Solution: Let A invested for X months.
Ratio of profit A : B = X × 19 : 19 × 15
So, 19X : 19×15 = 3:2
X = 22(1/2) months
Example 7:
Sandeep, Vineet and Shekhar are three partners. Sandeep receives 1/5 of the profit and Vineet and Shekhar share the remaining profit equally. If Vineet’s income is increased by Rs.650 when the profit rises from 10% to 15%. Find the capitals invested by Sandeep, Vineet and Shekhar and total capital invested.
Solution: As given, the profit share of Sandeep is 1/5, remaining profit (1-1/5) = 4/5 is shared between Vineet and Shekar equally.
So, the profit share of Vineet = 2/5 and profit share of Shekhar = 2/5
when profit % increases, Vineet’s income increase by Rs.650
(15%-10%) = 5% = 650
100% = 13000
So, Vineet’s capital = 13000
i.e (2/5) of total capital = 13000
total capital = 32500
and Shekhar’s capital = 13000
Sandeep’s capital i.e (1/5) of total capital or ½ of (Vineet or Shekhar’s Capital) = 6500
Example 8:
A and B are partners in a business. They invest in the ratio 5: 6, at the end of 8 months B withdraws. If they receive profits at the end of the year in the ratio of 5: 9, find how long A’s investment was used? (SBI PO Pre 2016 Memory based)
Solution: Let A’s investment used for X months.
Given, the ratio of invest (A: B) = 5: 6
ratio of time = X : 8
the ratio of profit = 5X: 6×8 and given ratio of profit = 5: 9
so 5X/48 = 5/9
X = 48/9
X = 16/3 months
Example 9:
A, B, and C started a business with their investments in the ratio 1: 2: 4. After 6 months A invested the half amount more as before and B invested the same amount as before while C withdrew (1/4)^{th} of his investment after the 9 months. Find the ratio of their profits at the end of the year. (SBI Clerk Mains)
Solution: Ratio of investments A:B:C = 1:2:4, there are no changes in the investment of A and B up to 6 months and in the investment of C up to 9 months.
At the end of 6 months, A invested half the amount more as before so A’s investment = 1 +(1/2)
Similarly B invest the same amount more as before = 2 + 2 = 4
But, C withdraw the (1/4)^{th }of the amount after 9 months = 4 – 1 = 3
ratio of profit = (1×6 + (3/2)× 6) : (2× 6 + 4× 6) : (4× 9+3× 3)
= 15 : 36 : 45
= 5 : 12 : 15
Example 10:
A sum of money is divided amongst P, Q and R in the ratio of 3: 4: 5. Another amount is divided amongst A and B in the respective ratio of 2: 1. If B got Rs. 1050 less than Q, what is the amount received by R?
Solution: Let the sum of money divided amongst P, Q and R is 3x, 4x and 5x respectively and the sum of money divided amongst A and B is 2y and y respectively.
4x – y = 1050
another relation between x and y cannot be established. So, it cannot be determined.
Directions (12-15): In the following table, the investments and profit of three persons is given for different years in a joint business.
| Investments (In Rs.) | Profit (In Rs.) | ||||
Year | A | B | C | A | B | C |
2010 | 15000 | ----- | 23000 | ----- | 82500 | 115000 |
2011 | ----- | 6000 | ---- | ---- | 15000 | 17500 |
2012 | ----- | ------ | 18000 | 42000 | 27000 | 24000 |
2013 | ----- | 17000 | 10000 | ---- | ----- | 14000 |
2014 | 11000 | 20000 | ---- | ---- | ---- | ---- |
Note:
1. Except for the year 2012, they invested the amounts for the same period.
2. Some values are missing. You have to calculate these values per given data.
Example 11:
If the total profit in 2011 is 45000, then find the ratio of the investment of B in 2010 to the investment of A in 2011.
Solution: profit of A in 2011 is 45000-(15000+17500) = 12500
B makes the profit of 15000 by investing 6000
So, investment of A in 2011 = (6000/15000)× 12500 = 5000
In 2010, 23000 investment of C makes the profit of Rs.115000
So, investment of B = (23000/115000)× 82500 = 16500
required ratio of (B:A) is 16500:5000 = 33:10
Example 12:
If the total investment in 2014 is 46000, then the ratio of profit in 2014 is?
Solution: investment of C is 46000 – (20000+11000) = 15000
The time period is the same, so the ratio of profit will be also the same as the ratio of investment = 11:20:15
Example 13:
In the year 2012 total investment of A and B is 30000, A and B invested their amount for 4 months and 6 months respectively then find the number of months that C invested his amount?
Solution: ratio of profit (A:B) = 42000: 27000
A× 4 : B× 6 = 42000 : 27000
A : B = 21 : 9 = 7 : 3
So, investment of A is 21000 and investment of B is 9000.
let C invest 18000 for X months.
So, (18000× X) : (21000 × 4) = 24000 : 42000
X = (8/3) months, Hence C invested for 8/3 months.
