Reasoning PYQs

Six people A, B, C, D, E, and F.

A is taller than D and C. 

B is taller than A but shorter than E. 

C is not the shortest person. 

D is shorter than only three-person. The third tallest person has 170 cm in height.

E > B > A > D > C > F

Now, A + E = 235------- (i)

and A + D = 220--------(ii)

A is the third tallest person = 115 cm

E = 235 - 115 = 120 cm

 Hence, the height of E is 120 cm.

Given,

i) B lives on an odd-numbered floor above floor 3.

From the above statement, we get two cases, i.e. Case-1 & Case-2

 

ii) Two people live between B and C.

From the above statement, we get two sub cases of Case-1, i.e. Case-1(a) & Case-1(b)

 

iii) Three people live between C and D.

 

iv) The number of people who live below C is equal to the number of people who live above A.

 

v) A lives on one of the floors above D.

From the above statement, this condition is violated. So, Case-2 is eliminated.

 

vi) F lives on two floors above C.

From the above statement, there is no place for F in Case-1(a). So, Case-1(a) is eliminated.

 

vii) G lives on one of the floors below E and H lives on one of the floors above G & E.

 

All of have 1 person sitting in between them except CD.

Hence, CD is the correct answer.

Given,

i) B lives on an odd-numbered floor above floor 3.

From the above statement, we get two cases, i.e. Case-1 & Case-2

 

ii) Two people live between B and C.

From the above statement, there is no place for F in Case-1(a). So, Case-1(a) is eliminated.

 

vii) G lives on one of the floors below E and H lives on one of the floors above G & E.

 

Four people live exactly between C and A.

Hence, 4 is the correct answer.

Putting all the signs step by step in place of @ and # we get:

S ≥ Z = R ≥ Y; A = Z ≥ B = N; N > Y is False

S ≥ Z = R < Y; A = Z > B = N;  N > Y is False 

S ≥ Z = R > Y; A = Z < B = N;  N > Y is True

S ≥ Z = R ≤ Y; A = Z ≥ B = N;  N > Y is Flase

S ≥ Z = R ≥ Y; A = Z > B = N;  N > Y is False

Hence, the correct answer is '>, <'

In G < H = I = J → J = H

In H > G > I = J → H > J → so in this statement H < J is definitely false.

In J = I ≥ G > H → J > H → so in this statement H < J is definitely true.

In H ≥ G > I < J → we can’t say whether H > J or H < J.

Hence in expression J = I ≥ G > H, H < J is definitely true.

Let us check each option:

1. Z > T ≥ L and P < A ≤ L → A ≤ T; B ≤ T and Z > T ≥ L → B < Z as required

2. Z > T ≥ L and P < A < L → A < T

3. Z ≤ T and B ≤ T → relation between B and Z can’t be determined.

4. Z < T and B = T → B > Z

Hence,>, ≤, ≤ are to be placed so that both A ≤ T and B < Z  hold definitely true.

The pattern followed here is;

As per the English alphabetical series,

D + 3 = G; G + 2 = I; I + 2 = K,

Z - 3 = W; W - 2 = U; U - 2 = S,

K + 3 = N; N + 2 = P; P + 2 = R,

Q + 3 = T; T + 2 = V; V + 2 = X,

H + 3 = K; K + 2 = M; M + 2 = O

Hence, 'ZWUS' is the odd one out.
