**Directions (1-5): Study the given information and answer the questions:**

When a number arrangement machine is given an input line of numbers, it arranges them following a particular rule. The following is an illustration of an input and its rearrangement.

Step IV, is the last step of the above arrangement as the intended arrangement is obtained.

As per the rules followed in the given steps find out the appropriate steps for the given input:

**Input: 61 22 15 52 71 36 18 11**

**Q1. What is the sum of the numbers at both the ends in step III of the given arrangement?**

(a) 22

(b) 44

(c) 53

(d) 72

(e) None of these

**Q3. What is the products of the numbers which is 2nd from the right end and 2nd from the left end in final step of the given arrangement?**

(a) 180

(b) 72

(c) 13.5

(d) 180

(e) None of these

**Q4. Which element is 2nd to the left of the one which is 4th from the left end in step II?**

(a) 22

(b) 44

(c) 89

(d) 72

(e) None of these

**Q5. What is the sum of the numbers at both the ends in step IV of the given arrangement?**

(a) 36

(b) 63

(c) 60

(d) 16.5

(e) None of the above

**Solutions (1-5): **

Sol. In this input output question numbers are arranged following different rules in each step. Let us understand the logic behind it- In each step the numbers are arranged

In step 1: the numbers are multiplied with 3 and then 2 alternatively.

Step 2: the first two numbers are subtracted, then 2nd and 3rd number are added and alternatively process is repeated till the last number.

Step 3: Multiplication of the digits of the resultant in the previous step.

Step4: The numbers in the previous step is divided by 2.

**Directions (6-10):** In each of the questions given below, a group of digits is given followed by four combinations of letters/ symbols numbered (a), (b), (c) and (d). You have to find out which of the four combinations correctly represents the group of digits based on the letter/ symbol codes and the conditions given below. If none of the four combinations represents the group of digits correctly, give (e) ‘None of these’ as the answer.

Condition for coding the group digits:

(i) If the first digit is odd and last digit is even, the codes for the first and the last digits are to be interchanged.

(ii) If the first as well as the last digit is even, both are to be coded by the code for the last digit.

(iii) If the first as well as the last digit is odd, both are to be coded as ‘X’.

**Directions (11-15): Study the following information carefully and answer the given questions. **

A, B, C, D, W, X, Y and Z are eight friends sitting around a square table, two on each side. All of them are facing away from the centre and each is opposite to another.
