# Reasoning: Machine Input-Output Questions Set 30

Directions (1-5): A string of numbers is given as input. The further steps given are obtained by applying certain logic. Numbers of step II have been obtained by using at least 1 digit of each number in step I. Each step is a resultant of previous step only.

Input:

1. What is the average of numbers obtained in last two steps?
A) 1.5
B) 2
C) 1
D) 2.5
E) Other than options given
Â Option C
Solution:
For given example:

Step I : follow the arrows
2+3= 5, 8+1= 9, 59
4+4=8, 3+2= 5, 85â€¦.
So step I: 59â€¦â€¦â€¦85â€¦..76
Step II: Numbers of step II have been obtained by using at least 1 digit of each number in step I.
(5+8)*7 = 91â€¦â€¦.(9+5)*6= 84
So step II: 91â€¦â€¦..84
Step III: Subtract, 8â€¦â€¦â€¦..4
Step IV: Average- (8+4)/2 = 6
For given input:::
Step I: 57â€¦..â€¦69â€¦â€¦..84
Step II:Â Â Â Â  Â 88â€¦…..64
Step III:Â Â Â  Â Â 0â€¦â€¦..2
Step IV:Â Â Â Â Â Â Â Â Â Â  Â 1Â
2. If 7 is added to the number obtained in last step, what is the resultant?
A) 10
B) 13
C) 15
D) 8
E) 9
Â Option D
3. What is the difference between the largest and the smallest number in step I and II respectively?
A) 18
B) 45
C) 20
D) 26
E) 35
Â Option C
Solution:
Required difference = 84 â€“ 64 = 20
4. Find the HCF of numbers obtained in all steps.
A) 4
B) 5
C) 0
D) 3
E) 1
Â Option E
Solution:
HCF is highest common factor among all numbers. All numbers have highest common factor as 1.
0 = 1*0Â
5. The digit â€˜8â€™ is seen how many times in any of the steps?
A) None
B) One
C) Three
D) Five
E) Two
Â Option C
Solution:
In 84 and 88Â
