You just need correct practice and hardwire your brain to quickly make decisions of what to attempt and what to leave. And for same we are providing you questions on Input-Output as per the 47 days study plan for RRB. To Practice more with these new pattern Reasoning Question for RRB PO Exam 2017.

(e) None of these

Q5. In step VI, ‘time’ is related to ‘on’ and ‘never’ is related to ‘put’. In the same way ‘fix’ is related to?
(a) time
(b) 11
(c) on
(d) and
(e) None of these

Solution (1-5):
Students let us understand the Logic behind this Question and let’s understand how to solve it. When we see the each step, then we can find that there is both number and words are arranged in each step.
1) For words arrangement- Words are arranged according to ascending order given in English dictionary. In first step the words which come first according to English dictionary arranged first to extreme right. And in second step next word according to English dictionary are arranged to extreme left.
And this process is continued in further step.
2) For number arrangement- Number are arranged according to ascending order. There are three odd number and three even numbers. In first three step odd number are arranged in ascending order first to extreme left end then to extreme right. And in last three step even number are arranged in ascending order. (Each odd number is added by 1 while they are arranged and each even number is subtracted by 1 while they are arranged).

Input:  17 and 32 on 12 never 29 time 7 put 4 fix
Step I:  8 17 32 on 12 never 29 time put 4 fix and
Step II:  fix 8 32 on 12 never 29 time put 4 and 18
Step III:  30 fix 8 32 on 12 time put 4 and 18 never
Step IV:  on 30 fix 8 32 12 time put and 18 never 3
Step V: 11 on 30 fix 8 32 time and 18 never 3 put
Step VI:  time 11 on 30 fix 8 and 18 never 3 put 31

(e) None of these

Solution(6-10):
Concepts for words arrangement:- Each words are arranged in ascending order according to English dictionary  from left to right.

Number arrangement→ There are three prime number and two odd number. First we arrange prime number in ascending order and then odd number in ascending order. Subtract one (-1) from each prime number while they are arranged & add one (+1) to each odd number while they are arranged.
