Question

A person is left with amount 4200 after deducting 10% income tax and deducting 12% for saving amount from the salary what is the salary of the person ?

Answer 1

let x be his salary
then deduction of 10% means left is 90%. And then after 12% deduction means 88% left with him so

x*(90/100)*(88/100) = saving =4200

solving it, x = 4200/(0.9*0.88)

x= Rs 5303.03

Answer 2

the equation will be x-(x/10)-(6x/25)=4200
                               =Rs.6,363.63636
