Question

amans income is 20% less than that of Anil how much percent is Anil income more than amans income

Answer 1

Let Anil's income be X:

Aman's income is 80/100 x  = 0.8x

The % will be found by Anil's income/Aman's income x 100%

(x/0.8x)100     .....cancel out the x

(1/0.8)100    =  100/0.8    =  1000/8  =  125%

There Anil's income is 125% more than Aman's

Answer 2

let the income of anil be 100
income os amans will be 80/100×100=80
thus anil's income - amans income will be
100-80=20
in percentage 20/100×100=20%
