Common Input tax credit

I have 1lakh of input on whole and ineligible ,input of exempted supplies comes to 35000 ,And I have both exempted supplies of 25000 and taxable supplies 60000 .How much amount of input should I book in my 3B for the electronic credit ledger?As far as I have studies it showed that total input (1lakh-35000) to be in electronic credit ledger and the proportionate itc to be reversed in Gstr-2 is that right or should I show the proportionate calculation in Gstr-3b itself? Please help me with this query!
