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 shortcuts 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 often comes in Quantitative Aptitude which is a very essential paper for banking exam. Given below 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
We can express 1% as 1/100. (1 part of total 100 part).
Similarly, we can say 10% as 10/100 (10 part of total 100 part),
And 50% as 50/100 (50 part of total 100 part).
If a student get 40% marks in Math that means student got marks in math is 40 out of 100 of full marks.
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% .
If the price of a commodity increases by R%, then the reduction in consumption as not to increase the expenditure is
[R / (100 + R) x 100]%
If the price of a commodity decreases by R%, then the increase in consumption as not to decrease the expenditure is
[R / (100 – R) x 100]%
Results on Population
Let the population of a town be P now and suppose it increases at the rate of R% per annual, then :
1. Population after n years = P(1 + R / 100)n
2. Population n years ago = P / (1 + R / 100)n
Result on Depreciation
Let the present value of a machine be P. Suppose it depreciates at the rate of R% per annual, 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
If A is R% more than B, then B is less than A by
[R / (100 + R) x 100]%
If A is R% less than B, then B is more than A by
[R / (100 – R) x 100]%
It help in fast calculation in percentage:
1 = 100%
1/2 = 50%
1/3 = 331⁄3%
1/4 = 25%
1/5 = 20%
1/6 = 162⁄3%
1/7 = 142⁄7%
1/8 = 121⁄2%
1/9 = 111⁄9%
1/10 = 10%
1/11 = 91⁄11%
1/12 = 81⁄3%
1/13 = 79⁄13%
25% = 1/4
6.25% = 1/16
125% = 5/4
150% = 3/2
200% = 2
350% = 7/2
