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: 41, 19, 218, 229, 317, 64, 107 Step I: 317, 19, 218, 229, 41, 64, 107 Step II: 317, 229, 19, 218, 41, 64, 107 These steps get repeated thereafter. The third step of a given input is 574, 479, 153, 79, 354, 432, 106, 84. What will be
Options
- A574, 479, 432, 354, 106, 153, 84, 79
- B574, 479, 432, 354, 79, 153, 106, 84
- C574, 479, 432, 354, 153, 106, 79, 84
- D574, 479, 432, 354, 153, 106, 84, 79
Correct answer
C. 574, 479, 432, 354, 153, 106, 79, 84
Step-by-step solution
Here the rule followed is the numbers are getting arranged in descending order. Step I: The largest of the given numbers interchanges its place with the first number. [In case the largest number is already arranged, the second largest is interchanged with the number next to the largest and so on.] Step II: The same process as that of step I will happen here but in this step, nos. will be shifted rightwards instead of interchange. Step III: 574, 479, 153, 79, 354, 432, 106, 84 (Given) Step IV: 574, 479, 432, 153, 79
