Step by step explanation:
To calculate p % of y
(p/100) x y = (p x y)/100
p % of y = y % of p
To find what percentage of x is y: y/x × 100
To calculate percentage change in value
Percentage change = {change/(initial value)} x 100
Percentage point change = Difference of two percentage figures
. Increase N by S % = N( 1+ S/100 )
Decrease N by S % = N (1 – S/100)
If the value of an item goes up/down by x%, the percentage reduction/increment to be now made to bring it back to the original point is 100x/ (100 + x) %.
If A is x% more /less than B, then B is 100x/(100 + x) % less/more than A.
If the price of an item goes up/down by x %, then the quantity consumed should be reduced by 100x/ (100 + x)% so that the total expenditure remains the same.
Successive Percentage Change
If there are successive percentage increases of a % and b%, the effective percentage increase is:
{(a + b + (ab/100)}%
