when the 30% deduction were not there the expenses of repair and maintenance were allowed from the rental income..... earlier it was the area for tax avoidance(e.g. people used to show expenses more then income or less rental income).... in order to pluck this lacuna the department gave 30% standard deduction from rental income so now only 30% allowed toward all expenses so people cannt declared the expenses more then rental income....
friend this is the actual reason behind 30% deduction from rental income......
