Reasoning paper in Bank P.O Exams presents a tough job of solving difficult problems in little time. Logical and simple Approach makes solution speedier for many Reasoning paper topics. Input-Output interpretations, Blood relationships, Sitting arrangement around circle and straight line, Puzzles, Inequalities, Possibility and conditional Conclusions in syllogism are regularly appearing topics in Bank P.O Exams. These questions are solved very speedily by Logical approach. Below are the Illustrations

Directions (9-13): Study the following information carefully and answer the questions given below:

Pete, Lila, Remo, Symon and Tom are five friends who travelled to five different cities- A, B, C, D, and E by three different modes of transport – train, aeroplane, and car from city Z not necessarily in the same order.

Directions (Q 14-16): In all the questions that follow different symbols have been used with different meanings. For each set of questions you have to assume given statements to be true and then decide which of the two given conclusions is/are definitely true.

Give answer:

(1) if only (a) is true

(2) if only conclusion (b) is true

(3) if either conclusion (a) or (b) is true

(4) if neither (a) nor (b) is true

(5) if both are true

Directions (14-16): In the following questions, the symbols @, #, $, &, + are used with the following meaning:

P @ Q means P is greater than Q.

P # Q means P is either greater than or equal to Q.

P $ Q means P is equal to Q.

P & Q means P is smaller than Q.

P + Q means P is either smaller than or equal to Q.

14. Statements: T @ V, V + W, W + X

Conclusions: (a) T @ X (b) W $ X

Ans. (4): (Statements: T > V, V ≤ W, W ≤ X) (Conclusions: (a) T > X (b) W = X)

Combined Inequality: T > V ≤ W ≤ X. Inequality signs between T and X in combined Inequality points in different directions so T > X does not follow. W = X is obviously false

15. Statements: L + K, M & R, K $ M

Conclusions: (a) R @ L (b) K + R

Ans. (1) : (Statements: L ≤ K, M < R, K = M)

(Conclusions: (a) R > L (b) K ≤ R)

Combined Inequality : L ≤ K = M < R. Inequality signs between L and R in combined notation points in same direction, so we have L < R (carry lighter ‘<’ sign) which means R > L. From combined Inequality we have K < R so K ≤ R is wrong.

16. Statements: X @ Y, Z + A, Y $ Z

Conclusions: (a) X @ A (b) Y $ A

Ans. (4): (Statements: X > Y, Z ≤ A, Y = Z) (Conclusions: (a) X > A (b) Y = A)

Combined Inequality notation: X > Y = Z ≤ A. Inequality signs between X and A in combined Inequality notation points in different directions so X > A does not follow. From combined Inequality notation we have Y ≤ A so Y = A does not follow

Possibility means probability more than zero and less than 100 percent. So to conclude possibility one must check that a given conclusion is not a sure event (100 percent) or not a possible event (Zero percent).

Three possible situations are

1. Possibility criteria is wrong for event being a sure event

2. Possibility criteria is wrong for event being a sure non occurring event

3. Possibility criteria correct. I.e. event is true in some but not all possible Euler figures.

To determine the validity of given type conclusions of the format: S who are P are not R by Raval’s method we have to check SS/RR or BB /RR if either of them is valid then S who are P are not R or P who are S are not R is true conclusion.
