Reasoning is a game of wits and presence of mind! Yes, it is true and it might seem as the greatest of the challenge after English Section’s surprises but yet this one can easily be dealt with. 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.

Solution

Solution (1-5):
Concepts for words arrangement:- Words are arranged according to reverse alphabetical order from right to left.

Number arrangement→ the largest number is arranged in extreme left in first step. And then smallest number is arranged at extreme left in second step. And in Step III second largest number is arranged. In Step IV second smallest number is arranged. And this process is continued in further step.

Solution(6-10):
Concepts for words arrangement:- There are total six words in which three words start from vowel letter while other three words start from consonant letter. The words which start from vowel arrange first alphabetically from left to right. And then words which start from consonant arrange from left to right alphabetically.

Number arrangement→ There are three prime number and three even number. Prime numbers are arranged in first three steps in ascending order. And then even number are arranged from left to right in ascending order.

Solution (11-15):
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.
a) For words arrangement- Words are arranged in ascending order according to English dictionary from left to right.
b) For number arrangement- Numbers are arranged in descending order according to right to left in each step.
