Choosing correct itr form

Hi, i am a partner in a firm. we share profit (50/50). we are not maintaining the regular books of accounts. Our nature of business is 14005 - other IT enabled services. And we are declaring Presumptive income @ 10 %. Gross recipt is less than 75000. we already filed ITR4 for our partnership firm. 

Now i need to file my (individual) returs. my income comes from profit in the firm and income from other source (interest from Fixed Deposit). Which ITR form is applicable for me.? ITR3 or ITR4. 

please.

Thanks
