Directions (6-10): 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. Find the addition of numbers obtained in step II.
    A) 113
    B) 167
    C) 88
    D) 104
    E) Other than options given
    View Answer
     Option D
    Solution:
    Step I: Subtraction.
    (8-3) (6-2) = 54………(4-1)(6-4) = 32…………16
    Step II: Multiplication of consecutive digits in each box.
    [Given that – Numbers of step II have been obtained by using at least 1 digit of each number in step I.] So
    5*3*1 = 15……………4*2*6 = 48
    Step III: Average.
    (1+5)/2 = 3……………(4+8)/2 = 6
    Step IV: Addition.
    (3+6) = 9
    So, now for given Input
    63…….43……..82……..27…….29…….14
    Step I: 44…..…26……..72
    Step II:      56……48
    Step III:    5.5……..6
    Step IV:          11.5   
  2. Find the multiplication of numbers obtained in steps III and IV.
    A) 228.5
    B) 379.5
    C) 354.5
    D) 318.5
    E) 273.5
    View Answer
     Option B
  3. If the digits of all numbers in step II are increased by 1 each, then what is the difference between the sum of numbers in step I and sum of numbers in step II?
    A) 16
    B) 17
    C) 14
    D) 15
    E) 19
    View Answer
     Option A
    Solution:
    In step II, 56 -> 67, and 48 -> 59
    So required difference = (44+26+72) – (67+59) = 16
  4. If all the decimal numbers are round off to their nearest greater integer, then how many numbers in all 4 steps are divisible by 4?
    A) Three
    B) One
    C) Four
    D) Five
    E) Two
    View Answer
     Option D
    Solution:
    In step III, 5.5 -> 6, In step IV, 11.5 -> 12
    So, numbers divisible by 4 are = 44, 72, 56, 48, 12
  5. What is the difference between the largest and second smallest number in any step?
    A) 42
    B) 75
    C) 63
    D) 47
    E) 66
    View Answer
     Option E
    Solution:
    Required difference = 72 – 6 = 66
