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

    View Answer
     Option C
    Solution:
    For given example:

    Step I : follow the arrows
    2+3= 5, 8+1= 9, 59
    4+4=8, 3+2= 5, 85….
    So step I: 59………85…..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 = 91…….(9+5)*6= 84
    So step II: 91……..84
    Step III: Subtract, 8………..4
    Step IV: Average- (8+4)/2 = 6
    For given input:::
    Step I: 57…..…69……..84
    Step II:      88……..64
    Step III:      0……..2
    Step IV:            1 
  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
    View Answer
     Option D
