    Solution

    Here the rule followed is: The sum of the digits is calculated. Then in step I, the number with lowest sum of its digits interchanges with the first number. [If the first number has already the lowest sum of its digits then the number with second lowest sum of its digits interchanges with the second number.] The process continues until the numbers get arranged in ascendingorder on the basis of their sum of digits.
