Percentage

In this post, we will learn about percentage.

Percentage 

• One percent (1%) means 1 per 100. 
• Fifty percent (50%) means half of total.
• Hundred percent (100%) means full or 100 out of 100 or 1000 out of 1000.
• Two hundred  percent (200%) means twice of original. for example if your salary is 12 Lakh and change your job and you salary become 36 Lakh in this case you salary increased by (36 - 12) = 24 Lakh means twice of original means your salary increased by 200 %.  

Calculate Percentage

Example: Calculate 25% of 80

 100% of 80 = 80  
 1% of 80 = (80/100)  
 25% of 80 = (80/100)x25  

Shortcut: X percentage of Y = (Y x X)/100 

If only 10 of the 200 apples are bad, what percent is that?

 In 200 apple 10 are bad  
 In 1 apple (10/200) will be bad  
 In 100 apple (10/200)x100 = 5% will be be bad   

Shortcut: X is k percentage of Y means X = (k*y)/100
