What is percentage?
Percentage is most important chapter and its shortcut tricks are need to know why because it uses other chapters for calculation like data interpretation chapter so we first learn percentage shortcut tricks and Percentage is  A fraction or a numerical expression or a ration with 100 assumed as denominator. So we can represent 1 percentage as 1%.
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.
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 are comes into action .

Basic fact and Formula
Now 1% we can express it as a 1%=1/100. Similarly we can write 10%=10/100 and 50%=50/100 ( 50 part of total 100 part ).
II. If a student get 40% marks in Math that means student got marks in math is 40 out of 100 of full marks.

III.
To Express p/q as a percentage:
We express it as p/q = (p/qx100)% .
so we can express like 1/4 = (1/4×100)% = 25% .
and Now, 0.4 = 4/10 = (4/10 x 100)% = 40% .
    IV. If the price of a commodity increases by R%, then the reduction in consumption as not to increase the expenditure is [R/(100+R)x100]%
    V. If the price of a commodity decreases by R%, then the increase in consumption as not to decrease the expenditure is [R/(100-R)x100]%

VI. Results on Population :
Let the population of  a town be P now and suppose it increases at the rate of R% per annul, then :
1. Population after n years = P(1+R/100)n
2. Population n years ago = P/(1+R/100)n

VII. Result on Depreciation :
Let the present value of a machine be P. Suppose it depreciates at the rate of R% per annul, then :
1. Value of the machine after n years =P(1-R/100)n .
2. Value of the machine n years ago = P/(1-R/100)n .

VIII.
If A is R% more then B, then B is less than A by
[R/(100+R)x100]% .
If A is R% less than B, then B is more than A by
[R/(100-R)x100]% .

Remember it :
It help in fast calculation in percentage:
1 = 100% 1/3 = 33×1/3%
1/2 = 50% 1/5 = 20%
1/4 = 25% 1/7 = 14×2/7%
1/6 = 16×2/3% 1/9 = 11×1/9%
1/8 = 12×1/2% 1/11 = 9×1/11%
1/10 = 10% 1/13 = 7×9/13%
1/12 = 8×1/3%
