Question
If β655, 436, 764, 799, 977, 572, 333β is the
input, which of the following steps will be β333, 436, 572, 655, 977, 764,799β? Directions : A number arrangement machine,when given a particular input, rearranges it following a particular rule. The following is the illustration of the input and the steps of arrangement: Input: 245, 316, 436, 519, 868, 710, 689 Step I: 710, 316, 436, 519, 868, 245, 689 Step II: 710, 316, 245, 519, 868, 436, 689 Step III: 710, 316, 245, 436, 868, 519, 689 Step IV: 710, 316, 245, 436, 519, 868, 689 Step IV is the last step for the given input.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.
