Problems Based on Input-Output
Direction for example:
Given an input line the relations arranges the words and numbers step by step in a systematic manner as illustrated below:
Input: subsidy 76 48 follow 35 next 63 must
Step I: 35 subsidy 76 48 follow next 63 must
Step II: 35 subsidy 48 76 follow next 63 must
Step III: 35 subsidy 48 next 76 follow 63 must
Step IV: 35 subsidy 48 next 63 76 follow must
Step V: 35 subsidy 48 next 63 must 76 follow
Output in Step V is the final output and Step VI is the last step. As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.
(a) Three (b) Four
(c) Five (d) Six
(e) None of these
(a) 17 restriction 67 pearls garland 85 93 judgement
(b) 17 restriction 67 pearls 93 garland 85 judgement
(c) 17 restriction 85 pearls 67 garland 93 judgement
(d) 17 restriction 67 pearls 85 garland 93 judgement
(e) None of these

(d) cannot be determined
(e) None of these
(a) 26 shop 37 music 48 finance game 63
(b) 26 shop 37 music finance 48 game 63
(c) 26 shop 37 music 48 game finance 63
(d) There is no fifth step
(e) None of these
(a) Seven (b) Five
(c) Four (d) Eight
(e) None of these
Solutions for I to V:
The given problem is a miscellaneous type of input - output problem based on arrangement of words and numbers.
The input is: subsidy 76 48 follow 35 next 63 must
The rule here is: In step I: smallest number (i.e. 35) goes to first place and in second step the word starting with the last letter of alphabetical order (subsidy) goes to second place, but here subsidy is already at second place so the second smallest number (i.e. 48 goes to third place in second step) and continuing in the same manner we get the final step. Now all the problems can be solved easily.
Step III: "11 white 37 direct 72 status front 69"
Step IV: "21 white 37 status direct 72 front 69"
Step V: "21 white 37 status 69 direct 72 front"
Step VI: "11 white 37 status 69 front direct 72"
Step VII: "21 white 37 status 69 front 72 direct" (Which is the last step)
Hence 5 more steps are needed.
Hence [C]
Step I: "17 restriction 85 pearls garland 67 93 judgement"
Step II: "17 restriction 67 85 pearls garland 93 judgement"
Step III: "17 restriction 67 pearls 85 garland 93 judgement"
Hence [D]
Hence [D]
Step III: "26 shop 37 finance 48 game music 63"
Step IV: "26 shop 37 music finance 48 game 63"
Step V: "26 shop 37 music 48 finance game 63"
Hence [A]
Step I: "23 56 punish 48 find design lavish 36"
Step II: "23 punish 56 48 find design lavish 36"
Step III: "23 punish 36 56 48 find design lavish"
Step IV: "23 punish 36 lavish 56 48 find design"
Step V: "23 punish 36 lavish 48 56 find design"
Step VI: "23 punish 36 lavish 48 find 56 design"
Hence [E]
