Profit and Loss is not a very big topic. So lets combine Profit and Loss, Partnerships and Percentages. I will post questions...!!!
HydRocker SaysProfit and Loss is not a very big topic. So lets combine Profit and Loss, Partnerships and Percentages. I will post questions...!!!
Still there are very good questions on P&L; left....U must have some good quality questions.....
Also I would give a way to remember %ages so that would take time....tooo...
Partnerships can be merged but we need to give a bit of time to %ages...some 3 days so that everybody remembers it properly ....

PROBLEMS :-
1) The Percentage increase in the value of Exports of apples of a country is as follows :
2001 - 2002 ---> 25%
2002 - 2003 ---> 20%
2003 - 2004 ---> 10%
What is the percentage increase in the value of exports of apples of the country from 2001 to 2004?
2)The length of a rectangle is increased by 10% and the breadth is increased by 20%. What is the consequent percentage increase in its area.?
3) If the price of an item goes up by 10%, by what percentage should the new price be reduced to bring it down to the original price?
4) If Dinesh's salary is 20% less than Eswar's salary, then by what percentage is Eswar's salary more than Dinesh's salary?

i know that method of percentages. I guess you wanted to say conversion of fraction to percentages and percentages to fractions. We shall do these 3 topics together. Lets take 5 more days and complete these topics. I will keep posting questions from all topics. As we are still doing basics i didn't post any difficult question yet...

Ok it looks good I suppose 5 days will be enough but pls all puys must actively participate in this otherwise we 2 are definitely there to discuss it out......but that would not make this thread successful.

Few Simple Concepts of Percentages :-
1) If there are successive increases of p%,q% and r% in three stages, the effective percentage increase is { ( 100+p/100)(100+q/100)(100+r/100)-1} * 100.
If one or more of p,q and r are decrease percentage figures and not increase percentage, then it will be taken as a negative figure and not as positive figure.
2) If the value of an item goes up/down by x% the percentage reduction/increment to be now made to bring it back to the original level is
100x/(100+/-x) %.
Note :- If A is x% more/less than B, then B is 100x/(100+/-x) % less/more than A.
3) When two articles are sold at the same price such that there is a profit of p% on one article and a loss of p% on another article then, irrespective of what S.P actually is, the net result of the transaction is LOSS.
Loss Percentage = (Common profit or loss)^2/100 = p^2/100

Not as of now as because we are currently going with P & L ,Partnerships and Percentages....If u are strong then you can obviously do what is to help...
We will be taking up Geometry a bit later.
Thanks

Nice initiative. I suggest everyone to watch Sir Ravi Handa's video in youtube.
Basics are awesome in those videos. I started my prep with those videos . All the best puys.
I am in even ๐ 
Percents:
What is a % of b? Problem Set-Up: x = (a/100)*b
a is what percent of b? Problem Set-Up: a = (x/100)*b
What % of a is b? Problem Set-Up: b = (x/100)*a
a is b% of what number? Problem Set-Up: a = (b/100)*x
a% of what number is b? Problem Set-Up: b = (x/100)*a
Percent Changes:
Percent Change (Actual Change/Original Value) * 100 %
Percent Increase ((New Value V Original Value)/ (Original Value)) * 100 %
Percent Decrease ((Original Value V New Value)/(Original Value)) * 100 %
To Increase a number by K%, multiply it by (100% + K%)
To Decrease a number by K%, multiply it by (100 - K%)
If a number is the result of increasing another number by K%, then, to find the original number, divide by (100% + K%)
If a number is the result of decreasing another number by K%, then, to find the original number, divide by (100% - K%)
Successive Percent Changes
Apply the following steps when two or more series of subsequent percent changes are applicable:
Step-1: Compute the first percentage change on the original base. If the original base is not given, assume it to be 100
Step-2: Add/Subtract the first percent change from the base of 100 to find the value after first percent change, also known as the intermediate value.
Step-3: Compute the second percent change on the value of first percent change
Step-4: Add/Subtract the second percent change from value after the first percent change to find the final percent change
Percent Discounts
Original Price = Sale Price + Discount Amount
Original Price = (Discount Amount/Discount %) * 100
Original Price = Sale Price / (100% + Markup %)
New Price Original Price (100 % + Mark-up %) or Original Price (100 % - Mark-up %)
Sale Price Original Price - Discount Amount
Discount Amount Original Price - Sale Price
Discount % (Rate of Discount) ((Original Price - Selling Price)/Original Price) * 100 (Discount Amount/Original Price) * 100
Percent Mark-Ups/Downs
Cost Price: Amount that costs the seller without any profit or loss. It is the cost that the seller pays or incurs to procure or produce an item.
Selling Price: Amount that a seller sells an item for, which may include a profit (mark-up) or loss (mark-down) or neither (break-even price)
Break-Even Price: Nothing but the Cost price
Mark-up or Profit = Selling price cost price
Selling Price = Cost Price + Profit
Original Price or Cost Price= Sale Price/ (100% + Mark-Up %)
New Price = Original Price + Mark-up (Increase)
Mark-down or Loss = Cost price - Selling price
Selling Price = Cost Price - Loss
Original Price = Sale Price/ (100% - Mark-down %)
New Price ฤฦยจ Original Price - Mark-Down (Decrease)
What is a % of b? Problem Set-Up: x = (a/100)*b
a is what percent of b? Problem Set-Up: a = (x/100)*b
What % of a is b? Problem Set-Up: b = (x/100)*a
a is b% of what number? Problem Set-Up: a = (b/100)*x
a% of what number is b? Problem Set-Up: b = (x/100)*a
Percent Changes:
Percent Change (Actual Change/Original Value) * 100 %
Percent Increase ((New Value V Original Value)/ (Original Value)) * 100 %
Percent Decrease ((Original Value V New Value)/(Original Value)) * 100 %
To Increase a number by K%, multiply it by (100% + K%)
To Decrease a number by K%, multiply it by (100 - K%)
If a number is the result of increasing another number by K%, then, to find the original number, divide by (100% + K%)
If a number is the result of decreasing another number by K%, then, to find the original number, divide by (100% - K%)

Percent Discounts
Original Price = Sale Price + Discount Amount
Original Price = (Discount Amount/Discount %) * 100
Original Price = Sale Price / (100% + Markup %)
New Price Original Price (100 % + Mark-up %) or Original Price (100 % - Mark-up %)
Sale Price Original Price - Discount Amount
Discount Amount Original Price - Sale Price
Discount % (Rate of Discount) ((Original Price - Selling Price)/Original Price) * 100 (Discount Amount/Original Price) * 100
Percent Mark-Ups/Downs
Cost Price: Amount that costs the seller without any profit or loss. It is the cost that the seller pays or incurs to procure or produce an item.
Selling Price: Amount that a seller sells an item for, which may include a profit (mark-up) or loss (mark-down) or neither (break-even price)
Break-Even Price: Nothing but the Cost price
Mark-up or Profit = Selling price cost price
Selling Price = Cost Price + Profit
Original Price or Cost Price= Sale Price/ (100% + Mark-Up %)
New Price = Original Price + Mark-up (Increase)
Mark-down or Loss = Cost price - Selling price
Selling Price = Cost Price - Loss
Original Price = Sale Price/ (100% - Mark-down %)
New Price ฤฦยจ Original Price - Mark-Down (Decrease)
#1. cost price of 12 articles = selling price of 15 articles . wat will be the profit or loss percentage????? just want ur approach as it is a cake walk to solve ????
#2. cost price of 25 articles = selling price of 20 articles. find profit or loss percentage ?????
In 6 q. 1920-x = x-1280
2x= 3200
x= 1600
In 10. q 6/5 - 5/6
= 36-25/30
= 11/30 which is equal to app. 39%

Guys for a person who nearly flunked his 10th board exams just because he was pathetic in maths...:banghead:
How should he start preparing for CAT quants...??
What materials should he start with..??
P.s : That guy is me

Start from the very basics . Don't go for any mock level questions. You should complete your basics by April. And in may you should do mock level questions and then start giving mocks and analyse. That will help...!!!!
Basically which area should i start from...??
#1. cost price of 12 articles = selling price of 15 articles . wat will be the profit or loss percentage????? just want ur approach as it is a cake walk to solve ????
#2. cost price of 25 articles = selling price of 20 articles. find profit or loss percentage ?????
1) lets say C.p of 1 article is x.
C.p of 12 articles = 12x = S.p of 15 articles
C.P of 15 articles = 15x
C.P > S.P (loss)
Loss = C.P - S.P = 15x - 12x = 3x
Loss % = 3x/15x * 100 = 20%
2) Lets say C.P of 1 article is x.
C.P of 25 articles = 25x = S.P of 20 articles
C.P of 20 articles = 20x
S.P > C.P ( Profit )
Profit = S.P - C.P = 25x - 20x = 5x
Profit % = 5x/20x * 100 = 25 %

PROBLEMS :-
1) The Percentage increase in the value of Exports of apples of a country is as follows :
2001 - 2002 ---> 25%
2002 - 2003 ---> 20%
2003 - 2004 ---> 10%
What is the percentage increase in the value of exports of apples of the country from 2001 to 2004?
2)The length of a rectangle is increased by 10% and the breadth is increased by 20%. What is the consequent percentage increase in its area.?
3) If the price of an item goes up by 10%, by what percentage should the new price be reduced to bring it down to the original price?
4) If Dinesh's salary is 20% less than Eswar's salary, then by what percentage is Eswar's salary more than Dinesh's salary?
1) Lets say the value is 100 in 2001
100 * 1.25 * 1.20 * 1.1 = 125 * 1.20 * 1.1 = 125 * 1.32 = 165
So the value increased by 65%.
Note :- You can use the formula also
{(100+p/100)(100+q/100)(100+r/100)-1} * 100
2) Let the length be l and breadth be b initially.
Length increases by 10% = 1.1 l
Breadth increases by 20% = 1.2 b
Area = l*b = 1.1 l * 1.2 b = 1.32 lb
So the percentage increase is area is 32%
3) Lets use the formula here .
100*x/100+x = 100*10/100+10 = 1000/110 = 9.09 %
OR
Let the value be 100. Now it is increased by 10%. So it becomes 110.
Now to bring it back to 100 we should decrease it by 10.
10/110 * 100 = 100/11 = 9.09%
4) Lets use the formula here.
100*x/100 -x = 100*20/100-20 = 200/80 = 25%
OR
Let Eashwar salary be 100.
Now dinesh salary is 20% less = 80
Eashwar salary is more than dinesh salary by 100-80 = 20
Percentage = 20/80*100 = 25%
