A number arrangement machine, when given a particular input,...

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\quad 41, \quad 19, \quad 218, \quad229, \quad 317, \quad 64, \quad 107 Step I: 317,19,218,229,41,64,107\quad 317, \quad 19, \quad 218, \quad 229, \quad 41, \quad 64, \quad 107 Step II: 317,229,19,218,41,64,107\quad 317, \quad 229, \quad 19, \quad 218,\quad 41, \quad 64, \quad 107 These steps get repeated thereafter. What will be the sixth step of the following input? Input: 320, 211, 59, 68, 119, 158, 63

Options

  1. A59, 211, 320, 119, 68, 158, 63
  2. B320, 211, 158, 119, 68, 59, 63
  3. C320, 211, 158, 119, 68, 63, 59
  4. DCannot be determined

Correct answer

D. Cannot be determined

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. Input: 320,211,59,68,119,158,63320, 211, 59, 68, 119, 158, 63 Step I: 320,211,158,68,119,59,63320, 211, 158, 68, 119, 59, 63 Step II: 320,211,158,119,68,59,63320, 211, 158, 119, 68, 59, 63 Step III: 320,211,158,119,68,63,59320, 211, 158, 119, 68, 63, 59 Since all the nos. are fully arranged in descending order only in three steps hence the machine will not operate on these numbers.
