What is Partnership?
Partnership: Persons  two or more than two persons when start and run the new  a business  jointly of there own choice, the persons start they are called partners and the deal is done between the partners 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 Rs. x and Rs. 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 Rs. x for p months and B invests Rs. y for q months then,
(A's share of profit) : (B's share of profit)= xp : yq.

A. Rs 2380
B. Rs 2300
C. Rs 2280
D. Rs 2260

ANSWERS AND SOLUTION :
1(B)Explanation:
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.
Now, 14x/8y  = 5/7  =>  98x = 40y   =>  y = 49/20 x
And, 14x/7z = 5/8 =>  112x = 35z    => z = 112/35 x = 16/5 .x.
So  x : y : z  =  x : 49/20 x : 16/5 x = 20 : 49 : 64.

2(D)Explanation :
The ratio of their initial investment = 1/2 : 1/3 : 1/4
= 6 : 4: 3
Let's take the initial investment of P, Q and R as 6x, 4x and 3x respectively
A:B:C = (6x * 2 + 3x * 10) : 4x*12 : 3x*12
= (12+30) : 4*12 : 3*12
=(4+10) : 4*4 : 12
= 14 : 16 : 12
= 7 : 8 : 6
B's share = 378 * (8/21) = 18 * 8 = 144

3(D)Explanation:
Let C = x.
Then, B = x + 5000 and A = x + 5000 + 4000 = x + 9000.
So, x + x + 5000 + x + 9000 = 50000
=> 3x = 36000
=> x = 12000
A : B : C = 21000 : 17000 : 12000 = 21 : 17 : 12.
So  A's share = Rs. (35000 x 21/50) = Rs. 14,700.

4(C)Explanation :
P:Q:R = (25*1+35*2) : (35*2 : 25*1) : (30*3)
= 95 : 95 : 90
= 19 : 19: 18

5(A)Explanation:
A : B : C = (20,000 x 24) : (15,000 x 24) : (20,000 x 18) = 4 : 3 : 3.
So  B's share = Rs. (25000 x 3/10) = Rs. 7,500.

6(C)Explanation :
Assume that investment of C = x
Then, investment of A =2x
Investment of B = 4x/3
A:B:C = 2x : 4x/3 : x = 2 : 4/3 : 1 =6 : 4 : 3
B's share = 157300 * 4/(6+4+3) = 157300*4/13
= 12100*4 = 48400

6(A)Explanation:
A : B : C = (10 x 7) : (12 x 5) : (15 x 3) = 70 : 60 : 45 = 14 : 12 : 9.
C's rent = Rs.(175 x 9/35) = Rs. 45.

7(D)Explanation :
Let P's capital = p, Q's capital = q and R's capital = r
Then
4p = 6q = 10r
=> 2p = 3q = 5r
=>q = 2p/3
r = 2p/5
P : Q : R = p : 2p/3 : 2p/5
= 15 : 10 : 6
R's share = 4650 * (6/31) = 150*6 = 900

8(C)Explanation :
Suppose C's capital = x then
B's capital = 4x (Since B's Capital is four times C's capital)
A's capital = 6x ( Since twice A's capital is equal to thrice B's capital)
A:B:C =6 x : 4x : x
= 6 : 4 : 1
B's share = 16500 * (4/11) = 1500*4 = 6000

9(C)Explanation :
Let the amount invested by Q = q
40000 : q = 2 : 3
=> 40000/q = 2/3
=> q = 40000 * (3/2) = 60000

10(A)Explanation:
Now as per question, Kamal invested for 12 months and Sameer invested for 7 months.
So  Kamal: Sameer = (9000*12):(8000*7)
= 108 : 56
=  27 : 14
Sameer Ratio in profit will be  =(6970*14/41)=Rs2380

Concept And Tricks Of Ratio And Proportion


Concept And Tricks Of Ratio And Proportion

What is Ratio?
A ratio is a relationship between two numbers by division of the same kind. The ration of a to b is written as a : b = a / b In ratio a : b , we can say that a as the first term or antecedent and b, the second term or consequent.


Example :  The ratio 4 : 9 we can represent as  4 / 9 after this 4 is a antecedent and , consequent = 9

Rule of ration :  In ratio multiplication or division of each and every term of a ratio by the same non- zero number does not affect the ratio.

Different type of ratio problem is given in Quantitative Aptitude which is a very essential topic in competitive exam. Under below given some more example for your better practice.
Anything we learn in our school days was basics and that is well enough for passing our school exams. Now the time has come to learn for our competitive exams. For this we need our basics but also we have to learn something new. That’s where shortcut tricks and formula are comes into action.

What is Proportion?
The idea of proportions is that two ratio are equal.
If a : b = c : d, we write a : b : : c : d,
Ex. 3 / 15 = 1 / 5
a and d called extremes, where as b and c called mean terms.

Proportion of quantities
the four quantities a, b, c, d said proportion then we can express it
a : b = c : d
Then a : b : : c : d  <–> ( a x d ) = ( b x c )
product of means = product of extremes.

If there is given three quantities like a, b, c of same kind then then we can say it proportion of continued.
a : b = b : c the middle number b is called mean proportion. a and c are called extreme numbers.
So, b^2 = ac. ( middle number )^2 = ( First number x Last number ).

TRICKS  FOR SOLVING QUESTIONS RELATED TO PROFIT AND LOSS:
COST PRICE : The price at which an article is purchased is called its cost price (C.P.)

SELLING PRICE : The price at which the article is sold is called its selling price (S.P.)

1. If the cost price (C.P.) of the article is equal to the selling price (S.P.), then there is no loss or gain.
2. If the selling price (S.P.) > cost price (C.P.), then the seller is said to have a profit or gain,
Gain/Profit = S.P. - C.P.
3. If the cost price (C.P.) > selling price (S.P.), then the seller is said to have a loss,
Loss = C.P. - S.P.
4.  Gain% = {(Gain*100)/C.P.}

5. Loss% ={(Loss*100)/C.P.}

6. S.P. = {(100+Gain%)/100 * C.P.}

7. S.P. = {(100 - Loss%)/100 * C.P.}

8. C.P. = {(100/(100+Gain%) * S.P.}

9.C.P. = {(100/(100 - Loss%) * S.P.}

10. If an article is sold at a profit/gain of 30%, then S.P. = 130% of the C.P.
11. If an article is sold at a loss of 20%, then S.P. = 80% of the C.P.
12. When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then in this transaction the seller always incurs a loss given by: 
                        {x^2/100}%
13. A single discount equivalent to discount series of x% and y% given by the seller is equal to 

                                   {x +y - xy/100}%

A. 1000
B. 2000
C. 1200
D. 920

ANSWER AND SOLUTION :

1(A)Explanation :
Let cost price of goods be Rs 100.
Gain = 20%
Therefore, Selling price = Rs 120
Discount = 25%
Marked Price = (100/100-25)x120
= Rs. 160
i .e.  60% more

2(D)Explanation :
If a trader professes to sell his goods at cost price, but uses false weights, then
Gain% = {Error/(True value - Error) x 100}%
In the given question, Error = 1000 - 850 = 150
Thus, Gain% = {150/(1000 - 150) x 100}%
= 17 11/17%

3(D)Explanation :
Let the cost price be Rs. x.
Selling Price at 10% loss = 90x/100
Selling Price at 15% gain = 115x/100
Thus, according to the problem,
115x/100 - 90x/100 = 40
x = Rs.160

4(D)Explanation :
Let the Cost Price (CP) of one article = 1
=> CP of x articles = x ------------------------------(Equation 1)
CP of 20 articles = 20
Given that cost price of 20 articles is the same as the selling price of x articles
=> Selling price (SP) of x articles = 20--------------(Equation 2)
Given that Profit = 25%
(SP-CP/CP)=25/100=1/4------------( Equation 3)
Substituting equations 1 and 2 in equation 3,
(20-x)/x=1/4
80-4x=x
5x=80
x=80/5=16

5(B)Explanation:
 Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
 Required percentage = (295/420 x 100)% = 1475/21 % = 70% (approximately).

6(C)Explanation :
Let CP = x
Percentage profit earned by selling an item for Rs. 1920
= (SP-CP/CP0 ×100
=(1920-x)/x×100
Percentage loss incurred by selling the same item for Rs. 1280
= (CP-SP)/CP×100
= (x-1280)/x ×100
Given that Percentage profit earned by selling an item for Rs. 1920=Percentage loss incurred by selling the same item for Rs. 1280
(1920-x)/x ×100 = x-1280/x ×100
(1920-x)/x = (x-1280)/x
1920–x = x–1280
2x=1920+1280=3200
x=3200/2
=1600
Required Selling Price = CP×125/100
=1600×125/100 =1600×5/4
=400×5=2000

7(D)Explanation:
Suppose, number of articles bought = L.C.M. of 6 and 5 = 30.
C.P. of 30 articles = Rs.(5/6 x 30) = Rs. 25.
S.P. of 30 articles = Rs.(6/5 x 30) = Rs. 36.
 Gain % =  (11/25 x 100) % = 44%.

8(A)Explanation:
C.P. of 1 orange = Rs.(350/100) = Rs. 3.50
S.P. of 1 orange = Rs (48/12) = Rs. 4
 Gain% = (0.50/3.50  x 100) %  = 100/7 % = 14 2/7%

9(B)Explanation :
CP of 1st variety rice=20
CP of 2nd variety rice=36
CP of the 56 kg rice mixture=(26×20+30×36)=520+1080=1600
SP of the 1 kg rice mixture=30
SP of the 56 kg rice mixture=30×56=1680
Gain=SP-CP=1680-1600=80
Gain%=Gain/CP×100=80/1600×100=100/20=5%

10(A)Explanation :
Let the labeled price=x
SP=704
Initial Discount=20%
Price after initial discount=x×80/100
Additional discount=12%
Price after additional discount=x×80/100 × 88/100
But Price after additional discount=SP=704
=> x×80/100 × 88100=704
=>x×4/5 × 22/25=704
=>x=704×25/22 × 5/4=176×25/22×5
=8×25×5=40×25=1000

Concept And Tricks On Average

What is Average
An average or more accurately an arithmetic mean is, in crude terms, the sum of n different data divided by n.
Averages of a group is defined as the ratio of sum of all the items in the group to the number of items in the group.

Average = (Sum of all items in the group)/ Number of items in the group

Now, sum of all items can be ‘the sum of number of quantities like apple, people etc’ or ‘sum of values of the item like 10 coins of 2Rs each etc’.

Some Important Concepts:

1. Average =total of data/No.of data

2. If the value of each item is increase by the same value a, then the average of the group or items will also increase by a.

3. If the value of each item is decreased by the same value a, then the average of the group of items will also decrease by a.

4. If the value of each item is multiplied by the same value a, then the average of the group or items will also get multiplied by a.

5. If the value of each item is multiplied by the same value a, then the average of the group or items will also get divided by a.

6. If we know only the average of the two groups individually, we cannot find out the average of the combined group of items.

7.Average of n natural no's=(n+1)/2

8.Average of even No'=(n+1)

9.Average of odd No'= n

10.General Formula=(1st number +Last number)/2
