Input Output - Technique to Solve Quickly

Believe me, this is one of  the easiest topic of reasoning because what matters here is speed because accuracy flows in with practice.

Students get stuck with these questions and waste their precious time because it lures them being easy but lengthy to solve once not practiced.

Lets get into the race and start thinking like examiners as what mistakes they are expecting from us.So we'll expertise in this topic today and will make sure that this easiness doesn't harm our time in the exams.

Rule

There are certain patterns followed in these type of questions. We need to study the pattern and then follow the same pattern in the question asked.

Types:

Type1 : When the pattern consists of only numbers:

Example 1: An electronic device rearranges numbers step by step in a particular order according to set rules. The device stops when the final result ie step 4 is obtained. Study the arrangement and answer the following question.

Input    55   89   23   67   87   90  

Step 1   90   55   89   23   67   87

Step 2   90   89   55   23   67   87

Step 3   90   89   87   55   23   67

Step 4   90   89   87   67   55   23

question: What is the fourth element to the left of last element in step 3 of the following input  ?

INPUT   43  61  13  76  23  82

options:

a) 61                      b) 76                      c) 23                       d) 82                      e) none of the above

Solution: Now following the same pattern given above, we would obtain the final output for this given input as follows:

Step 1   82   43   61   13   76   23

Step 2   82   76   43   61   13   23

Step 3   82   76   61   43   13   23

Step 4   82   76   61   43   23   13--- FINAL OUTPUT

ANSWER: b

Type 2 : When the pattern consists of only words:

Example 2 :      Input        have an ace up your sleeve

Step 1   ace  have   an   up   your   sleeve

Step 2   ace   an   have   up   your   sleeve

Step 3   ace   an   have   sleeve   up   your

Question: What will be the step 2 of the following input?

INPUT   laugh all the way to bank

OPTIONS:

a)  all   bank   to   the   way   laugh

b)  all   bank   laugh  way   the   to

c)  all   bank   laugh   the   way   to

d) all   bank   laugh   to   the  way

e) none of the above

Solution: Now following the same pattern given above, we would obtain the final output for this given input as follows:

Step 1   all   laugh   the   way   to   bank

Step 2   all   bank   laugh   the   way   to

Step 3   all   bank   laugh   the   to   way

ANSWER: c

Type 3: When the pattern consists of both the numbers and words

Example 3:          INPUT   34   best   86   19    of   56   your    78    ability

Step 1   19   34   best   86   of   56   78   ability   your

Step 2   19   34   56   best   86   78   ability   of   your

Step 3   19   34   56   78   86   ability   best   of   your

Question:  How many steps are required to get the final output?

input         beyond   87   the  93  12   call  22  of   duty

options:

a) 2                         b) 3                        c) 4                         d) more than four            e) none of the above

Solution: Now following the same pattern given above, we would obtain the final output for this given input as follows:

Step 1   12   beyond  87   93   call   22   of   duty   the

Step 2   12   22   beyond   87   93   call  duty   of   the

Step 3   12   22   87   93   beyond   call   duty   of   the

ANSWER: b
