Presumptive taxation scheme

Mr. X is an individual having manufacturing business with Turnover of Rs. 90 lacks. And other income of Rs. 5 lacks and 2 lacks including sale of fixed assets & interest on fixed deposit respectively (related to his business). He opts for Presumptive taxation scheme. Now my question is whether his business income is 8% of 97 lacks or 95 lacks? I.e. whether interest on FD shall be included in calculation of Business income under PTS or it will come under “Other Sources”.
