How to approach Reasoning Ability in RBI Grade B

The puzzles and seating arrangements carry the most marks and take the most time, so the skill is choosing which set to attempt and which to leave. Clear the quick scoring topics — inequality, syllogism, coding-decoding, blood relations — first, then spend the remaining time on one or two puzzles you can actually finish.

Sample Reasoning Ability questions with solutions

Written to the RBI Grade B pattern, with the answer key and the method behind it — a look at how the section is actually set before you drill the full topic sets.

Scheduling puzzle · solved example

Seven people - A, B, C, D, E, F and G - have an examination on seven different days of the same week, from Monday to Sunday, one examination each day. E has the examination on Wednesday. G has the examination on Sunday. Exactly one person has the examination before F. D has the examination immediately before F. C has the examination immediately after A. B has the examination immediately before A.

Who has the examination on Tuesday?

  • B
  • C
  • D
  • E
  • FCorrect

Solution

The single person before F is D on Monday, which places F on Tuesday.

Box puzzle · solved example

Six boxes - P, Q, R, S, T and U - are stacked one above another. The bottom position is 1 and the top is 6. Box P is at the top. Box S is at the bottom. Box Q is placed immediately above box R. Exactly three boxes are placed below T. Box U is placed immediately above T.

Four of the following five have a box immediately below them and so form a group based on their positions in the stack. Which one does not belong?

  • R
  • Q
  • T
  • U
  • SCorrect

Solution

R, Q, T and U each have a box directly beneath them in the stack. S is the bottom box, with nothing below it, so S is the odd one out.

Floor puzzle · solved example

Six people - P, Q, R, S, T and U - live on six different floors of a building. The lowest floor is numbered 1 and the highest is numbered 6. T lives on an even-numbered floor. Two people live between T and P. R lives on the floor immediately above Q. S lives on the topmost floor. U does not live on floor 1.

Which of the following statements is true of the final arrangement?

  • T lives immediately above U.
  • Exactly three people live above R.Correct
  • P lives on an even-numbered floor.
  • Q lives immediately below S.
  • None of these

Solution

The arrangement from floor 1 upward is P, Q, R, T, U, S. R is on floor 3, so floors 4, 5 and 6 are above it, holding T, U and S: exactly three people, making B true. A reverses the pair, since U on 5 is above T on 4. C is false because P is on floor 1, which is odd. D is false because Q is on 2 while S is on 6, with three people between them.

Syllogism · solved example

Statements: Some books are files. No file is a folder. Conclusions: I. Some books are not folders. II. All files are books.

  • Only conclusion I followsCorrect
  • Only conclusion II follows
  • Either I or II follows
  • Neither I nor II follows
  • Both I and II follow

Solution

The books that are files cannot be folders, since no file is a folder, so some books are not folders - I follows. II claims all files are books, but the statement only says some books are files, which does not force every file to be a book, so II does not follow.
