Reasoning: Machine Input-Output Questions Set 22 (SBI PO Pattern)

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 step 2?
    A) 23
    B) 26
    C) 25
    D) 35
    E) Other than options given
    View Answer
     Option A
    Solution:
    For given example:

    For given input:::
    Step I: 89……78…..86
    Step II:     23……23
    Step III:     1.5……..1.5
    Step IV:           0 
  2. What is the second largest number obtained in any step of given input?
    A) 89
    B) 86
    C) 78
    D) 23
    E) 45
    View Answer
     Option B
  3. Find the difference between sum of numbers obtained in 1st step and sum of numbers obtained in all other steps.
    A) 211
    B) 221
    C) 225
    D) 204
    E) 215
    View Answer
     Option D
    Solution:
    Required difference = (89+78+86) – (23+23+1.5+1.5+0)
  4. What is the difference between the largest and the third smallest numbers obtained in any steps?
    A) 84
    B) 70
    C) 66
    D) 61
    E) 58
    View Answer
     Option C
    Solution:
    Required difference = 89 – 23
  5. What is the average of numbers obtained in last 2 steps?
    A) Other than given in options
    B) 0.5
    C) 2
    D) 1.5
    E) 1
    View Answer
     Option E
    Solution:
    Required average =(1.5+1.5+0)/3 = 1 

Directions (6-10): Consider the following steps for given input and read the instructions to reach to the last step.

Instructions:
Step-I: Interchange the alphabets in input as arrows mentioned

Step-II: (i) If both letters are consonant and number is less than 6, then consonants change to previous letter in English alphabetical series.
(ii) If there is one vowel and one consonant, then add 4 to the number.
(iii) It there is single consonant, then consonant changes to next letter in English alphabetical series.

Step-III: has been derived using a special pattern taking similar (but not exactly) patterns of both step I and step II.

  1. What is the sum of all numbers in step II of given input?
    A) 42
    B) 40
    C) 33
    D) 36
    E) 43
    View Answer
     Option A
    Solution:

    In step III, we see that same number of alphabets are at same position, A changes to B, UM to TM, T to U, so if we take same pattern of step I, i.e. keeping letters constant and exchanging, we get the second figure as in below::

    Now try some application in this second figure as were given for step-II:
    We see when there is single letter, letter change to next letter.
    When both are consonants, then number is (number-2) e.g QF6 –> QF4
    And when one is vowel and other consonant, then vowel changes to previous letter and number to (number+1).  like in BI8 B is B, I -> H and 8->(8+1)9
    For given input:

  2. In last step, which of the following letter/s occur more than 1 time?
    A) C
    B) P
    C) N
    D) Both T and F
    E) Both N and T
