An employed  person receives HRA along with medical allowences in addition to basic and DA components. He calculates HRA exemption according to the rule: amount of rent paid in excess of 10% of salary. Now here salary is sum of basic and DA and excluding HRA, medical allowences and arrears. Is this method  correct?
