Easy pps read full question ans below salary of a person was reduced by 10% by what percent should his reduced salary be raised so as to bring it at par with his original salary answer pls explain last step ans is below how 1.11 becomes 11 percent let's say that a person earned $100 per day before the salary reduction. then, $100 - ($100 x 0.10) = $100 - $10 = $90 the percentage needed to get back to the original salary is given by x% x $90 = $100 solving for x, we get x = $100 / 90 = 1.11, so the person needs an 11% increase to restore the original pay
