Question

my income is 25% more than my friend s income by how much %his income is less than my income

Answer 1

let your income "a" = 25%

and total income "b" = 100%

a / b = 25 / 100 = 1 / 4

let,here a =1 , b = 4

you friend's income will be
{a / ( b +a ) } % less than you .

{a / ( b + a) } % = { 1 / (4 + 1)} %

=(1 / 5 )%= 1 /5 × 100

= 20 %

hence , his income is 20% less than you .
