Directions: (1-5)Study the following information carefully and answer the given questions:
A number arrangement machine when given an input line of numbers rearranges them following a particular hide in each step. The following is an illustration of input and rearrangement.
And step 11 is the last step of the above input. As per the rules followed in the above step, find out the appropriate step for the given output. INPUT: erode rose 23 village 19 strong 39 42 apple 18
1.In step 8, what is the sum of fourthelement from right end and fourthelement from left end?
A. 47
B. 28
C. 39
D. 48
E. None of these
Show Correct Answers
D. 48
Logic: – Starting with numbers-
for number arrangement:
First we will find out the addition of numbers.
For ex: 23 = 2 + 3 = 5, 19 = 1 + 9 = 10
39 = 3 + 9 = 12, 42 = 4 + 2 = 6, 18 = 1 + 8 = 9
So, greatest addition is 12(39 = 3 + 9), so, 39 will arranged first from left side and same additional value is placed to the extreme right end.
For example:
Step 1: 39 erode rose 23 village 19 strong 42 apple 18 12
And this process will be continue in very alternate steps for arrangement of numbers, And after arrangement numbers is shifted to right side in every next alternate step.
for word arrangement: – we have to find no. of vowels in every word of input
Example: erode = 3 (e, o, e), village = 3(i, a, e)
Strong = 1 (o), apple = 2(a, e)
So, word which have greatest no. of vowels will arranged first from the right end. And if words having same number of vowels then we have to compare first vowels of two words and greatest rank of vowel will arranged first.
Example: – erode = 3 (e, o e) village = 3(i, a,e)
“i” has greater rank then “e”. So, village will arranged first and succeeding letter of last letter of “village” will replace first letter of “village”. Now-
INPUT: erode rose 23 village 19 strong 39 42 apple 18
Step 1: 39 erode rose 23 village 19 strong 42 apple 18 12
Step 2: 39 erode rose 23 19 strong 42 apple 18 12 fillage
Step 3: 19 39erode rose 23 strong 42 apple 18 12 fillage 10

Step 5: 18 19 39 rose 23 strong 42 apple 12 fillage 10 frode 9
2.What is the position of ‘strong’ in the step fifth?
A. Seventh from the left end
B. Sixth from the left end
