## Percentage Practice Solved Questions for Exams : Understanding the Concept of Percentage

Percent means for every 100 So, when percent is calculated for any value,

it means that we calculate the value for every 100 of the reference value.

- Percent is denoted by the symbol %. For example, x percent is denoted by

x% - x% = x/100, e.g.: 25%=25/100=1/4
- To express x/y as a percent, we have x/y=(x/y×100)%Example: 1/4=

(1/4×100)%=25% - If the price of a commodity increases by R%, the reduction in consumption

so as not to increase the expenditure = [R/(100+R)×100]% - If the price of a commodity decreases by R%, the increase in consumption

so as not to decrease the expenditure = [R/(100−R)×100]% - If the population of a town = P and it increases at the rate of R% per

annum, then Population after n years = P(1+R/100)n - If the population of a town = P and it increases at the rate of R% per

annum, then Population before n years = P/(1+R/100)n - If the present value of a machine = P and it depreciates at the rate of R%

per annum, Then Value of the machine after n years = P(1−R/100)n - If the present value of a machine = P and it depreciates at the rate of R%

per annum, Then Value of the machine before n years = P/(1−R/100)n
