Gain = (S.P) – (C.P)
15% Profit on item that means,
Cost price 100%
Selling Price 115%
Profit 15%

2. If Cost price is more then Selling price is called Loss.
Loss = ( C.P ) – ( S.P )
15% Loss on article that means,
Cost price 100%
Selling Price 85%

Profit or Gain Percent Shortcut Tricks

We are follow some important facts and formula without this we are not able to calculate any profit or Gain percent any articles using shortcut tricks.when we purchase some item and then sell it we make profit some time depends on the cost price and selling price of an particular item. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam.Under below given some more example for your better practice.
• Note : In case in Profit and Loss, the relation is between C P and S P is :
If Profit 30% accrued on an article its mean to we say that
• Cost Price of Particle is 100%
Selling Price of Particle is 130%
Profit of Particle after Selling 30%
• Formula: Gain % = (Gain x 100/C.P)
Example 1 : Rana purchase an ball for Rs.80 and sells it for Rs. 100. Find his gain percent.
Answer: C.P = 80 and S.P = 100.
Gain= 100 – 80 = 20
Gain % = 20 x 100/80 = 25%
So,his gain percent is 25%.
Example 2 : A farmer purchase an article for Rs.25 and sells it for Rs. 28. Find his gain percent.
Answer: C.P = 25 and S.P = 28.
Gain= 28 – 25 = 3
Gain % = 3 x 100/25 = 12%
So, his gain percent is 12%.
Example 3 : Sabir purchase an article for Rs.40 and sells it for Rs. 60. Find his gain percent.
Answer: C.P = 40 and S.P = 60.
Gain= 60 – 40 = 20 .
Gain % = 20 x 100/40 = 50%
So, his gain percent is 50%
Example 4: A untruthful retailer sell his product at cost price however uses a weight of 950 grams for a kg weight. Find his gain percent.
Answer : we apply gain% formula
1 Kg = 1000 grams.
Profit of untruthful retailer = ( 1000 grams – 950 grams ) = 50 grams.
Gain% = [ Error x 100 / ( True Value ) – (Error) ]%
50 x 100 / 950 = 100 / 19%
So, his gain percent is 100 / 19%.
Example 5: A women went to shop to bought chocolate at 6 for a rupee. To gain 20% profit how many for a rupee she sail ?
Answer : Cost price 6 chocolate 1 rupee.
So, To Gain 20% of 1 rupee = 100 / 120 = 5 / 6.
= 5 x 6 / 6 = 5.
To gain 20% profit she sail for a rupee of 5.

Example 6: Sunita bought a TV for Rs.18000, and sold it by Rs.22000, How much profit she get ?
Answer : ( 22000 – 18000 ) = 4000.
profit she get = 4000 x 100 / 18000 = 200 / 9 = 22.222222222%.
So, his gain profit is 22.222222222%.

Loss Percent Shortcut Tricks

We are follow some important facts and formula without this we are not able to calculate any Loss percent of any articles using shortcut tricks.when we purchase some item and then sell it we make Loss on some time depends on the cost price and selling price of an particular item.
This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below given some more example for your better practice.
Suppose Mr, Roy is an owner of a bakery shop he sell different product and due to some reason he can’t make profit means he sells product with loss, loss means selling price of a product is less than the cost price.
Remember always that profit and loss are always counted on cost price, and cost price is also 100% in profit and loss.
• Loss percent Shortcut tricks
Formula: Loss% = (Loss x 100/C.P)

Example 1:

A man purchased a toy for Rs. 120 and sold it for Rs. 90, Find the loss Percent.
C.P = 120 and S.P =90
So We Know the formula of Loss = C. P – S.P . Loss = (120 – 90) = 30
Loss% = 30 x 100/120 = 25%
So, the loss Percent is 25%.

Example 2:

Anil purchased a mobile for Rs. 12000 and sold it for Rs. 8000, Find the loss Percent.
C.P = 12000 and S.P =8000
So We Know the formula of Loss = C. P – S.P, Loss = (12000 – 8000) = 4000
%Loss = 4000 x 100/12000 = 33.33%
So, the loss Percent is 33.33%

Example 3:

10% loss on selling price is what percent loss on the cost price ?
consider selling price be = Rs.100, Then loss = Rs.10
Cost price = Rs.( 100 + 10 ) = 110
So, loss% = ( 10 / 110 x 100 ) = 100 / 11 %

Example 4 :

A farmer purchased a cow for Rs. 200 and sold it for Rs. 180, Find the loss Percent.
C.P = 200 and S.P =180
So We Know the formula of Loss = C. P – S.P . Loss = (200 – 180) =20
%Loss = 20 x 100/200 = 10%.
So, the loss Percent is 10%.

• Find selling Price Profit and Loss Shortcut tricks
Formula: S.P = (100+Gain%)/100 x C.P.

Example:

We can find the Selling Price of article Using this above Formula
If C.P of a product is a Rs. 180, Gain = 30%, then Find the S.P.
S.P = 130% of Rs. 180, Gain = ( 100+30 ) = 130, ( 130 / 100 x 180 ) = Rs. 234
So, Selling Price is Rs. 234

Shortcut Tricks
130/100 x 180 = 234.

• Formula: S.P = (100 – Loss%)/100 x C.P

Example:

If C.P of a product is a Rs. 180 , Loss = 30%, then Find the S.P.
S.P = 70% of Rs. 180, Loss = (100 – 30) = 70, ( 70/100 x 180 ) = Rs. 126
So the Selling Price is Rs. 126

Shortcut Tricks
70/100 x 180 = 126

Example :

Rajan bought a bike for Rs.60,000 and spent Rs. 4000 on repair and Rs. 1000 on transport and sold it with 25% profit. What price did he sell the car ?
Solution:
Cost price =Rs. 60,000 Spent on repair =Rs. 4000 transport =Rs. 1000 and profit 25%
So, Cost price =Rs.( 60,000 + 4000 + 1000 ) = Rs. 65,000
So, Selling price = Rs. 65,000 x 125 / 100 = 81250.

Profit and Loss Example

We can find the cost Price of an article using this Formula we are follow some important facts and formula without this we are not able to calculate any Loss percent of any articles using shortcut tricks.
when we purchase some item and then sell it we make profit or loss some time it depends on the cost price and selling price of an particular item. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below given some more example for your better practice.

Example 1 :

If the C.P is 75% of the selling price, then What is the profit percent ?
Let S.P = Rs 100,
Then C.P = 75
Profit = Rs 25
Profit% = ?
= 25x 100 / 75
= 100 / 3 = 33.3
Profit % = 33.3

Example 2 :

Find the single discount equivalent to a series discount of 30%, 20% and 10%.
Let price be Rs. 100.
Then Net S.P = ( 90 x 80 x 70 / 100 x 100 x 100 ) x 100
= 36 x 7 / 5
= 252 / 5
= 50.4
Required Discount is = ( 100 – 50.4 ) = 49.6

Example 3 :

A Farmer purchased a cow and carriage for Rs. 3500. He sold the cow at a gain of 35% and the carriage at loss of 10%, So gaining 2% on the entire. Find the cost of the cow.
We consider C.P of the cow Rs. x
Then C.P of the Carriage Rs. ( 3500 – x )
So,
35% of x – 10% of ( 3500 – x ) = 2% of 3500
( 35x / 100 ) – 10( 3500 – x ) / 100 = 2 x 3500 / 100
( 7x / 20 ) – ( 3500 – x ) / 10 = 70
7x – 2x 7000 = 1400
5x = 5600
x = 5600 / 5
x = 1400.
the cost of the cow is 1400.

Example 4:

If the cost price of 14 pens is equal to the selling price of 8 pens, the gain percent is :
Let C.P of each pen is Rs. 1.Then
C.P of 8 pens = Rs. 8 : S.P price of 8 pens = Rs. 14
Gain % = 6 x 100 / 8 = 75%
the gain percent is 75%.

Example 5 :

The Profit gained by selling an item for Rs.630 is equal to the loss incurred if the same article is sold for Rs. 370. To gain 50% profit what would be the sale price ?
Let C.P price be x
Then
630 – x = x – 370
2x =1000
x = 500
Required S.P = 150% of 500
= 150 x 500 / 100
= 750
the sale price for making 50% profit is 750.
