# Partnership - Concept and Problems

Partnership is an important chapter in Quantitative section of IBPS and other banking examination.

When two or more people joins hands with a common goal to attain profits. Every partner invests either time, money or his patents to help partnership firm to reap profits.

There are many problems in partnerships regarding profit shares, investment period etc. I will try to solve one question from each part.

Question - Raj invested Rs 76000 in a business. After few months Monty joined him and invests Rs 57000. At the end of year both of them share the profits at the ratio of 2:1. After how many months Monty joined Raj ?

Solution - We can simply compute per month investment of both partnership

Raj invested Rs 76,000 for 12 months and Monty invested Rs 57,000 for x months.

Now 76000 × 12 / 57000 × x = 2 :1

⇒ 76 × 12 / 2 = 57x

⇒ x = 8

So Monty invested his money for 8 months and he joined after 4 months.

Question - A and B started a business by investing money in ratio of 5:6. C joined them after few months by sharing an amount equal to B's share. At the end of year 20% profit was earned which was equal equal to Rs 98,000. How much money was invested by C ?
Solution -
= First of all we will calculate the weighted ratios

⇒ A = 5 × 12 = 60
⇒ B = 6 × 12 = 72
⇒ C = 6 × 6 = 36

Total investment at the end of year = 98000 × 100/20 = Rs 4,90,000

⇒ Investment by C = 490000 × 36 / 168 × 2 = Rs 210000

Question -A, B and C shared profits in ratio of 5:7:8. They partnered for 14 months, 8 months and 7 months respectively. What was he ratio of their investments ?

Solution - Simply multiply profit sharing ratio with investment ratio to get investment amount ratio.

Let X is the total investment

⇒14 x = 5
⇒ 8 x = 7
⇒ 7x = 8

⇒ Final investment ratio = 20 : 49 : 64

Question - Sita and Geeta started a business by investing Rs. 120000 and Rs.135000 respectively. Find the share of each out of an annual profit of Rs. 35700.
Solution :-
• When investors are there for the different duration of  time in the business , then the investments are calculated for  a unit of time by having ( investment x number of units of time) . Now gain or loss is divided in the ratio of these investments.
Question - Ravi started a business by investing Rs.36000. After 3 months Shayam joined him by investing Rs.36000. Find the share of each in the annual profit of Rs. 37100.
Solution -

Solution -

1. hello sir, i want some tricky questions on different concepts, like permutations & combinations, partnership etc. so pls provide me by sending it on my mail id. i'll be very thankful to you

1. Try to increase your speed. Remember you need to solve at least 1 question in a minute.

2. Thank you for the guidance Sir.
In the 2nd prob, I did not get how, C=6*6 when the no.of months C invested for is not mentioned in the question. Also could you please elaborate the last step in the same prob? Same with the last prob. I did not understand how you arrive at the final investment ratio with the 3 implications.

1. Second Problem : I think that's not few months its 6 months...

Third Problem :

Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively..

Then 14x:8y:7z = 5:7:8

14x/8y = 5/7 ---> y= (49/20)x

and 14x/7z = 5/8 ---> z= (16/5)x.

we can find x:y:z
x:y:z = x : (49/20)x : (16/5)x
x:y:z= 20:49:64

2. Thanks Chidipilli, noticing that you are answering many queries. Thanks a lot for helping me.
