Profit and Loss Tricks:

• Trick(1): Agar x articles ke cost price y articles ke selling price ki equal hua to 

Profit% = [(x-y)/y X 100]%, x>y and Loss% = [(y-x)/y X 100]%, y>x.

Example1: Mann legiye 25 articles ke cost price 20 articles ke selling price ke barabar hai, yesme profit percent kya hoga.
profit% = [(25-20)/20 X 100]% = (5/20) X 100 = 25%, x>y
Example2:  12 articles ke cost price 16 articles ke selling price ki barabar hai,loss percent kya hai?
loss% = [(16-12)/16 X 100] = (4/16) X 100 =25%, y>x.

• Trick(2): Agar y articles ke cost price x rupees and x articles ke selling price y rupees hua to

profit% = [(y^2 - x^2)/x^2 X 100]%, y>x and loss% = [(x^2 - y^2)/x^2 X 100]%, x>y.

Example1: 5 banana ke cost price 4 rupees and 4 banana ke selling price 5 rupees,profit percent kya hai. profit% = [(5^2 - 4^2)4^2 x 100]% = 9/16 X 100% = 225/4%

Example2: 4 banana ke cost price 5 rupees and 5 banana ke selling price 4 rupees, loss percent kya hai. loss% = [(5^2 - 4^2)/5^2 X 100]% = 9/25 X 100 = 36 %.

• Trick(3): Jab koi article ke uppar two times x% and y% profit kiye jata hai tube resultant profit hoga  [ x + y + (xy)/100 ]%

Note: Agar x% and y%, koi ek yaa dono loss samjayega , tube trick me x and y ke jaga -ve  sign use karna hoga.

Example:  A sells a bicycle to B at a loss of 10% but B sells it to C at a profit of 30% . what is the resultant profit or loss?
x = -10%, y = 30%. profit or loss = [-10+30-(10 X 30)/100] = 17%
yaha hum dekhe rahe hai ki 17% ki sign +ve he,isliye resultant profit = 17%.
