Answer» ary of an employee is increased by 20%. By what PERCENTAGE should the new salary be reduced to restore the original salary?The salary of an employee is increased by 20%. By what percentage should the new salary be reduced to restore the original salary?Taking the sample value to be 100.A 20% increase MEANS 100*1.2=120.Thus a total increase of 20.Now let's find the ratio of 20 to 120 i.e., 20/120=0.1666.Changing to percentage 0.1666*100=16.6%.Hence, a decrease of 16.6% to the new salary will restore the original salary.Hope this HELPS!Thanks, |
