Capital gains on gold bond plus presumptive income

Hello

Greetings to you

My sovereign gold bonds matured this year and i have earned capital gains on its maturity, which is tx free

I file my itr under sec 44ada presemtive income scheme for professionals (50% profit ) in itr 4. (Income less than 10 lakhs)

My query is 

Should i fill itr4 as usual and put the gains amount in exempt income tab provided in itr 4 

Or 

Should i  fill itr 3 because it  is meant for income from capital gains plus business income and fill the presumpfive income tab in itr3

Thanks 

Regards
