Directions (1-5): Study the following information carefully and answer the given questions.
A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement.
Input: 42 chair 65 rocket 29 egg 98 still 85 52 holy apple.
Step I: apples 42 chair 65 rocket egg 98 still 85 52 holy 28
Step II: 41 apples 65 rocket egg 98 still 85 52 holy 28 chairs
Step III: eggs 41 apples 65 rocket 98 still 85 holy 28 chairs 51
Step IV: 64 eggs 41 apples rocket 98 still 85 28 chairs 51 holys
Step V: rockets 64 eggs 41 apples 98 still 28 chairs 51 holys 84
Step VI: 97 rockets 64 eggs 41 apples 28 chairs 51 holys 84 stills
Step VI is the last step of the above arrangement.
As per the rules followed in the steps given above, find out in each of the following questions the appropriate step for the given input.
Input: call 85 76 implicit land 59 94 under ape sold 15 90.
1. In which step are the elements ’apes 94 under sold 90’ found in the same order?

Step VI is the last step of the above arrangement.
As per the rules followed in the steps given above, find out in each of the following questions the appropriate step for the given input.
Input: call 85 76 implicit land 59 94 under ape sold 15 90.
1. In which step are the elements ’apes 94 under sold 90’ found in the same order?
(a) Fifth
(b) Seventh
(c) Third

(a) under
(b) apes
(c) 90

SOLUTION
Directions (9-13):
Logic: In the given machine input, in first step smallest letter
according to dictionary is arranged with addition of “s” at
extreme left side and the smallest number among all by
subtracting “1” is arranged at extreme right side and in next step
second smallest number among all by subtracting “1” is arranged
at extreme left side and second smallest letter according to
dictionary is arranged with addition of “s” at extreme right side.
And this process is continued upto last step.
Input: call 85 76 implicit land 59 94 under ape sold 15 90.
Step I: apes call 85 76 implicit land 59 94 under sold 90 14
Step II: 58 apes 85 76 implicit land 94 under sold 90 14 calls
Step III: implicits 58 apes 85 land 94 under sold 90 14 calls 75
Step IV: 84 implicits 58 apes 94 under sold 90 14 calls 75 lands
Step V: solds 84 implicits 58 apes 94 under 14 calls 75 lands 89
Step VI: 93 solds 84 implicits 58 apes 14 calls 75 lands 89 unders
