Reasoning PYQs

Given: Seven persons – D, E, F, G, H, J and K go to purchase different stationary items on seven different days of a week starting from Monday to Sunday, but not necessarily in the same order. The different stationary items are- Pencil, Eraser, Scale, Books, Marker, Highlighter and Pen.

1. E goes to purchase item immediately before J.
2. Three persons purchase stationary items between J and the one who purchased Books.
3. J purchased item before the one who purchased Books.
4. The number of persons go to purchase item after E is same as the number of persons go to purchase item before K who purchased Marker. 

There are 2 cases i.e., Case 1 and Case 2.

 

5. Three persons go to purchase item between K and the one who purchase Scale.
6. The one who go to purchase Scale purchased it two persons before H.
7. D purchased Highlighter.
8. D purchased the item after J. 

 

9. As many persons purchased between the ones who purchased Highlighter and Eraser as between Eraser and G. 
10. Pencil was purchased before Pen but not immediately before. 

Case 1 is eliminated because Pencil will come just before Pen. So, the final arrangement: 

 

Correct combination: G- Pencil

Hence, the correct answer is ‘G- Pencil’.

Given

Statements:

T ≥ M ≥ Q; G < O ≤ K; V > G ≥ T; C = O

On combining: K ≥ C = O > G ≥ T ≥ M ≥ Q; V > G

Conclusions

I. C = V → False (C = O > G and V > G → relation between C and V cannot be determined.)

II. K ≥ M → False (K ≥ C = O > G ≥ T ≥ M → K > M)

III. G ≥ Q → True (G ≥ T ≥ M ≥ Q → G ≥ Q)

Thus, only conclusion III is true.

Given

Statements:

O > F ≥ E; K < L ≤ Q; P = L; E > P; Z ≥ Q

On combining: Z ≥ Q ≥ L = P > K; O > F ≥ E > L = P

Conclusions

I. K < O → True (O > F ≥ E > L = P and L = P > K → O > K)

II. F > P → True (F ≥ E > L = P → F > P)

III. O ≤ Z → False (Z ≥ Q ≥ L = P and O > F ≥ E > L = P → relation between O and Z cannot be determined.)

Thus, both conclusions I and II are true.

Given

Statements:

J ≤ K = L ≤ M, P > J ≥ R = S, A < B < S < C.

Conclusions:

I) L > P → False (as, L = K ≥ J < P → Thus clear relation between L and P cannot be determined.)

II) K > C → False (as, K ≥ J ≥ R = S < C → Thus clear relation between K and C cannot be determined)

III) B < J → True (as, B < S = R ≤ J → B < J)

Hence only conclusion III is True

Given: Nine boxes R, S, T, U, V, W, X, Y and Z are placed one above the other in a stack but not necessarily in the same order.

1. Five boxes are placed between box T and box Z.
2. Box W is placed two boxes below box Z.
3. Number of boxes placed between box W and box T is three more than the number of boxes placed below box S. 

There are 3 cases i.e., Case 1, Case 2 and Case 3. (Because five boxes are placed between T and Z) 

 

4. One box is placed between box S and box X.
5. Box U is placed five boxes above box R. 

Case 2 is eliminated because there is no place for X. Case  1 is eliminated because there is no place for box U and R. 

 

6. Box Y is not placed above box V. So, the final arrangement is:

 

I. Two boxes are placed above box Z. This is false.

II. Box U is placed above box W. This is true. 

III. Box R and S are adjacent boxes. This is false.

Hence, the correct answer is ‘Only II’.
