Question

After increasing 12.5 % a person gets Rs 2700 .find his previous income

Answer 1

let previous income be x
x+12.5% × x = 2700
x+125/1000× x = 2700
x+x/8 = 2700
9x/8 = 2700
x = 2700×8/9
x = 2400
previous income = rs 2400

Answer 2

your answer is :-

let the original income be x
increased income %=12.5%
increased income :-
=x+12.5%ofx
=x+125x/1000
=1125x/1000

Given his increased income =Rs 2700
=>1125x/1000=Rs 2700
=>x=Rs 2700*1000/1125
=>x=Rs 2400

So Your Answer is Rs 2400
