Machine Input Output is an important chapter for IBPS exams. Most of the students don't know about the right approach to solve these questions. Today, I am providing the right approach for solving the Machine Input Output questions in the exams. Read shortcut trick for this chapter here.

- Machine Input/Output is scoring chapter in Quant because if once you understand the pattern, your all answers will be correct. As we know, there are many type of patterns in which questions are arranged. We have to understand that patterns and solve our questions.

- If you trying to solve these questions through traditional way that means you are wasting your time. Here are some shortcut tricks which can help you solving the questions quickly and saves your precious time during competitive exams.

## Different Types of Questions Used in Questions

### 1st Type of Questions

- How many steps are required to complete the following arrangement

### 2nd Type of Question

- When particular step is given in the question and you have to find the last step or any other step (i.e. find the fourth or fifth or third step)

### 3rd Type of Question

**Output**is given and you have to find the**Input**

(If question is asked that Output is given and find the Input, your answer always should haveNone of These)

### 4th Type of Question

- Which one will be the final arrangement?

### 5th Type of Question

- Which step will be last but one step

("Last but one step" meansSecond Last Step)

### Tricks

- Always remember,
**First Step is to observe Last Step.** - Last step in the question say much about that particular question. First of all, while solving the question last step should always be in consideration.

Lets understand all these thoroughly through some questions.

**Question**

**Input: but 32 71 glory fair south 65 84**

**Step I: south but 32 71 glory fair 65 84**

**Step II: south 84 but 32 71 glory fair 65**

**Step III: south 84 glory but 32 71 fair 65**

**Step IV: south 84 glory 71 but 32 fair 65**

**Step V: south 84 glory 71 fair but 32 65**

**Step VI: south 84 glory 71 fair 65 but 32**

In the above question it carries six steps that does not means all questions will contain same steps.

- To solve the question we have to understand the logic behind above rearrangements and to understand the logic observes the
**last step first.**

- If we see the output the order is first of all Alphabets comes then numbers, again alphabets and then again numbers and so on.

- Alphabets are in the decreasing order (reverse order) means alphabets are arranged in dictionary manner like Z to A. that is south, glory, fair and but
**in Output.**

- In the Output, Numbers are in decreasing order such as 84, 71, 65 and 32.

- From the output, we can understand each step ahead.In the Output,
**south**comes first that means in the first step they brought forward**south**and other numerical/alphabetical values remain same - Now again comes to Output. After the word
**south,**you can see**84.**It means in Step II, 84 move. You can easily observes that in Step II,**84**brought forward after**south**and other values remain same.

- Then in Step III,
**glory**comes forward after**84**and other values remaining same.

- In Step IV,
**71**comes forward after**glory**and other values remaining same. - In Step V,
**fair**comes forward after**71.** - In Last Step,
**65**after**fair**and other values remaining same.

- As a result of above arrangements, we easily found the pattern of output.

Now we have to answer the questions;

**Q1. Input: any hen 49 24 far wide 34 69****Find the output****.**

**Answer:**
Step I: wide any hen 49 24 far 34 69

Step II: wide 69 any hen 49 24 far 34

Step II: wide 69 any hen 49 24 far 34

Step III: wide 69 hen any 49 24 far 34

Step IV: wide 69 hen 49 any 24 far 34

Step V: wide 69 hen 49 far any 24 34

Step VI: wide 69 hen 49 far 34 any 24

Step IV: wide 69 hen 49 any 24 far 34

Step V: wide 69 hen 49 far any 24 34

Step VI: wide 69 hen 49 far 34 any 24

- It will consume much time. You don't have any need to write. Just from the output in question solve accordingly by this you can save your precious time during exam.

**Q2. After how many steps you can get output?**

**Answer:**We don't have any need to solve step by step. Simply after observing the output we can give the answer of steps like diagram below

- Take one common point.
**Wide**brought forward then numerical value**69**and so on as we see the pattern earlier.**any**and**24**does not show with arrows because they are automatically in their proper place after**34**brought forward.

**Number of Arrows = Number of Steps**

**Q3. How many more steps are required to complete the arrangement given below:**

**year 92 ultra 15 23 string house 39**

**Answer:**

- Now take help of arrows
- Number of arrows are 4 that means
**4 steps**more required to complete the arrangement according to output.

**Q4. What will be Third step if:-**

**Input: play over 49 37 12 match now 81**

a) play 81 over 49 37 match now 12

b) play 81 over 49 37 12 now match

c) play 81 over 49 now 37 match 12

d) There will be no such step

c) play 81 over 49 now 37 match 12

d) There will be no such step

**Answer:**- Put
**81**forward and cross its previous position then**over**and**49**is already in its right positions so no further cancellation.**Now**brings forward and cross its previous position.**37**is in its right position then**Match**brings forward and cancel its previous position. No further cancellation because**12**is automatically at the end.**Number of crosses on diagram shows the number of steps.**

**3 crosses are on the diagram that means 3 steps are done and answer is Option C.**

**Q5. What will be the 'definite' input if**

**Step II: Town 74 pair 15 31 nice job 42**

**Answer:**

- Answer of this question will be
**Can not be determined**because position of**74**can not be determined in step I, it may be after pair, after 15 after 31 and so on. But question is asked about definite input which is impossible. If he ask about**possible input**then we can take guess but now the case is**definite**input so answer will be**Can Not be Determined.**
