Reasoning PYQs

Eight : persons A, B, C, D, E, F, G and H 

1. Only one person seat between G and A.

2. F and G seats opposite to each other and facing each other.

3) B seats third to the left of A.

4. G does not seat to the immediate left of  B.

Using this statement, case 2 will be eliminated.

5. E does not seat between A and F.

So, E sits between A and G.

6. D does not sit adjacent to B.

7. H and D are immediate left of each other.

The final arrangement is shown below:

F, H, A and G are sitting on the corners.

Hence, FHAG is the correct answer.

The final arrangement is shown below:

 

Hence, A is sitting immediate right of E.

Forward: (5, 9), (2, 4)

Backward: (2, 7), (2, 8)

Hence, four such pairs are there in the number ‘857169224’, each of which has as many digits between them in the number (both forward and backward direction) as they have between them in the natural number series.

Given statements: M < U ≥ Y > D; X ≥ B > U

On combining: X ≥ B > U > M; X ≥ B > U ≥ Y > D

Conclusions:

I. M < X → True (as X ≥ B > U > M → X > M)

II. B > D → True (as B > U ≥ Y > D → B > D)

Hence, Both I and II are True.

Given statements : M > A ≥ T > F = Y ≤ S < P 

Conclusions: 

I: F < P → True ( as F = Y ≤ S < P → F < P )

II: A > S → False ( as A ≥ T > F = Y ≤ S → A > Y and Y ≤ S ) → thus clear relation between A and S cannot be determined

Therefore, only conclusion I is True.

Given statements:  A ≥ B ≤ C > D > E < F = K ≥ M

Conclusions:

I. A > C → False ( as A ≥ B ≤ C → thus clear relation between A and C cannot be determined)

II. E ≤ M→ False ( as E < F = K  ≥ M→ thus clear relation between E and M cannot be determined)

Hence, Neither I nor II is True.

Given: A certain number of people are sitting in a linear row facing North.

Based on the given conditions, we get the following possibilities:

1. R sits fifth from the left end of the row.

Only two persons sit between R and G, who sits to the right of R.

Combining these, we get-

2. X sits second to the left of G.

Three persons sit between X and A, who sits second from the right end of the row.

Combining these, we get-

3. Only one person sits to the left of L.

L sits third to the left of R.

Combining these, we get-

4. V sits sixth to the right of R.

From this, we get the final arrangement as follows:

Therefore, we see that the total number of persons sitting in the row is 11. 

Hence, the total number of persons sitting in the row is 11.

From the given instructions:

Eight people P, Q, R, S, T, U, V and W, they have different designation as General Manager, Deputy General Manager, Assistant General Manager, Manager, Assistant Manager, Sectional Officer, Cashier and Clerk. The order of seniority is same as given above i.e. General manager is the senior-most and the Clerk is the junior-most. So, we can a draw a structure as:

 

1. Only five people have their designations between S and V. Sectional Officer is senior to V. So, we have two cases:

 

2. More than two people are senior to Q. Q is immediately junior to W. U is senior to at least three designations. U is junior to W. Only three people have their designation between P and U.

So, from above conditions we can say that U can only be placed at Assistant Manager. So, we can say,

 

So, here we can clearly see that Case 1 is invalid, as there is no space to place P. So, Case 1 gets cancelled out.

3. S is senior to R, who is senior to T.

So, Final Arrangement:

 

R is the Sectional Officer.
