Percentage problems tricks(SSC,BANK,PO)

Percentage is a fraction whose denominator is always 100. x percentage is represented by x%. To express x% as a fraction :  We know x% =  x /100 Thus 10% =  10 /100 (means 10 parts out of 100 parts) =  1 /10 (means 1 part out of 10 parts) To express x/y as a percentage : We know that  x /y  = ( x /y× 100 ) Thus  1 /4 = (  1 /4 ×100 )% = 25% and 0.8 = (  8 /10 ×100 )% = 80% If the price of a commodity increases by R%, then reduction in consumption as not to increase the expenditure is- [  R / (100+R) ×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) ×100 ] % Result on Population :  Let the population of a town be P now and suppose increases the rate of R% per annum, then : Population after n years = P ( 1+  R /100 ) n   Population  n years ago =  P  / ( 1+  R /100 ) n  ...
