Direction (1 - 3): Study the following information carefully and answer the given questions :

A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement.

Input : 96 gain 63 forest 38 78 deep house

Step I : deep 96 gain 63 forest 38 78 house

Step II : deep 38 96 gain 63 forest 78 house

Step III : deep 38 forest gain 96 63 78 house

Step IV : deep 38 forest 63 gain 96 78 house

Step V : deep 38 forest 63 gain 78 96 house

Step VI : deep 38 forest 63 gain 78 house 96 and Step VI is the last step of the rearrangement of the above input.

As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.

1. Input: train 59 47 25 over burden 63 sky

5. Who is to the immediate left of T?

(1) Q (2) W (3) R (4) Date inadequate (5) None of these

 

Direction (6 - 10): In the following questions, the symbols ⋆, δ %, @ and © used with the following meaning as illustrated below:

'P % Q' means 'P is not smaller than Q'.

'P © Q' means 'P is neither smaller than nor equal to Q'.

'P ⋆ Q' means 'P is neither greater than nor equal to Q'.

'P 5 Q' means "P is not greater than Q'.

'P @ Q' means 'P is neither greater than nor smaller than Q'.

Now in each of the following questions assuming the given statements to be true, find which of the three conclusions I, II and III given below them is/are definitely true and given your answer accordingly.

(2) Only II and III are true

(3) Only I and III are true

(4) All I, II and III are true

(5) None of these

 

7. Statements:

Z@M, M © K , K ⋆ F

Conclusions: I. F © Z

II. K • Z

III. F © M

(1) None is true

(2) Only I is true

(3) Only II is true

(4) Only III is true

(5) Only II and III are true

 

8. Statements:

Conclusions: I. M * J

II. B © M

III. W ⋆ B

(1) None is true

(2) Only I is true

(3) Only II is true

(4) Only III is true

(5) Only I and III are true

 

9. Statements:

Answers

(1 - 3): After careful analysis of the given input and various steps of rearrangement, it is clear that in the first step one word is rearranged and in the second step one number is rearranged. These two steps are continued alternatively till all the words get rearranged in alphabetical order and all the numbers get rearranged in ascending order.

1. 2;

Input: train 59 47 25 over burden 63 sky

Step I: burden train 59 47 25 over 63 sky

Step II: burden 25 train 59 47 over 63 sky

Step III: burden 25 over train 59 47 63 sky

Step IV: burden25 over 47 train 59 63 sky

Step V: burden25 over 47 sky train 59 63

Step VI: burden 25 over 47 sky 59 train 63

2. 5;

Input: service 46 58 96 over there desk 15

Step I: service 46 58 96 over there 15

Step II: desk 15 services 46 58 96 over there

Step III: desk 15 over 46 services 46 58 96 there

Step IV : desk 15 over 46 service 58 96 there

Step V : desk 15 over 46 services 58 there 96

3. 4; It is possible to determine the input from any given step.

(4 - 5):

Sitting arrangement

4. 5; In none of pairs the third person is sitting between the first and the second persons.

5. 1; Q is to the immediate left of T.

(6 - 10):

6. 4; R δ K = R < K

K * M = K < M

M @ J = M = J

Therefore, R < K < M = J

Conclusions

I. J © K = J > K : True

II. M © R = M > R : True

III. R * J = R < J : True

7. 1; Z @ M = Z = M

M © K = M > K

K * F = K < F

Therefore, Z = M > K < F

Conclusions

I. F © Z = F > Z: Not True

II. K * Z = K < Z: Not True

III. F © M = F > M: Not True

8. 2; B * J = B < J

J % W = J > W

W © M = W > M

Therefore, B < J > W > M

Conclusions

I. M * J = M < J: True

II. W * B = W < B: Not True

III. B © M = B > M: Not True

9. 5; V % H = V > H

H @ F = H =F

F δ E = F < E

Therefore, V > H = F < E

Conclusions

I. F @ V = F = V: Not True

II. F * V = F < V: Not True

F is either smaller than or equal to V.

Therefore, either I or II is true.

III. E % H = E > H: True

10. 1; W © T = W > T

T δ N = T < N

N % D = N > D

Therefore, W > T < N > D

Conclusions

I. D * T = D < T: Not True

II. W © N = W > N: Not True

III. D @ T = D = T: Not True Advertisements
