Question

a income is 10% more than b income by how much percent is b income less than that of a

Answer 1

Let B income be x
So, A income = 10% + x
Loss = x - 10x / 100
         = - 9x / 100
Percent Of Decrease = Loss / 100 * CP
                                   = - 9x / ( 100 * 100 ) * x
                                   = - 9x / 10000 * x
                                   = - 9 x ^ 2 / 10000

Answer 2

let income b be x
so, 10/100×b + b= a
b/10 + b= a
(b+10b)/10 =a
11b/10=a ...eq 1

like this solve for b and put the value of a
