i have have income from two house property and i have not maintain books of account then how can i file income tax return

You dont need to maintain books of accounts to file ITR of House Property. All You need is details of Total amount of Rent which you have received, details of house tax/property tax which you have paid Any interest on housing loan paid during the year. You need to file ITR 2 (if not doing business) or ITR 4(If doing business also) For details on how to compute Income from House Property,you can refer http://teachoo.com/subjects/income-tax/income-from-house-property/
