题目内容

某分包商承包了某专业分项工程，分包合同中规定：工程量为2400m3；合同工期为30d，6月11日开工，7月10日完工；逾期违约金为1000元/d。该分包商根据企业定额规定：正常施工情况下(按计划完成每天安排的工作量)，采用计日工资的日工资标准为60元/工日(折算成小时工资为7.5元/h)。延时加班，每小时按小时工资标准的120%计；夜间加班，每班按日工资标准的130%计。该分包商原计划每天安排20人(按8h计算)施工，由于施工机械调配出现问题，致使该专业分项工程推迟到6月18日才开工。为了保证按合同工期完工，分包商可采取延时加班(每天延长工作时间，不超过4h)或夜间加班(每班按8h计算)两种方式赶工。延时加班和夜间加班的人数与正常作业的人数相同。[问题] 若采取夜间加班方式赶工，加班期内白天施工平均降效5%，夜间施工平均降效15%，需加班多少天（计算结果四舍五入取整）
