Rajaram’s monthly income is distributed in 5 expense heads namely house rent, groceries, transport expenses, electricity and water expenses and finally under the head miscellaneous expenditure. After meeting these expenses, the remaining amount (which is non zero) goes towards savings which is a fixed percentage of his income every month. It is known that these amounts can be expressed as percentage of his income as 6 distinctive integers. The percentage expenses under 5 heads are 5 integers such that difference between 2 consecutive expenses is a constant. The minimum percentage of his income that he saves per month is _______.
