Triangular based seating arrangement

Directions (1-4): Study the following information carefully and answer the questions below.

Eight people are sitting in a triangular table. There is 1 chair placed at each corner, 3 chairs are kept on one edge and 2 chairs each are kept on remaining two edges. The persons on the corner of the table are facing away from center and the persons on edge of the table are facing center. Each person likes different number viz. 13, 14, 16, 19, 21, 24, 27 and 32.No two adjacent chairs are vacant.

F, who likes prime number, sits four places away from the one who likes 32. C sits fourth to the left of the one who likes 21, who sits on the immediate right of G. K, who likes even number, sits third to the left of the one who likes 32. C neither sits at any corner nor sits adjacent to F. G neither sits adjacent to the one who likes 24 nor sits at corner of the table. Sum of the numbers liked by F and C is equal to the number liked by B. The one who likes 21 neither sits adjacent to F nor sits adjacent to H. Two persons sit between R and the one who likes a number which is a perfect square. H, who likes 32, sits facing opposite direction to that of K. Sum of numbers liked by B and D is twice the number liked by K. One person sits between D and B, who neither sits adjacent to F nor sits at corner. B sits second to right of the one who likes 19.

Statement-Assumptions

Directions 9-10: In the question given below, there is a statement followed by two assumptions numbered I and II. An assumption is something supposed or taken for granted. You have to consider the statement and assumptions and then decide which of the assumption(s) is/are implicit in the statement.

Answers :

Directions (1-4):

We have:

  • K, who likes even number, sits third to left of the one who likes 32.
  • H, who likes 32, sits facing opposite direction to that of K.

That means, in case (1) K sits on corner, in case (2) H sits at corner.

  • F, who likes prime number, sits four places away from the one who likes 32.

That means, in case (1a) & case (2a) F sits fourth to right of H, in case (1b) & case (2b) F sits fourth to left of H.

Based on above given information we have:

Again, we have:

  • C neither sits at any corner nor sits adjacent to F.
  • C sits fourth to the left of the one who likes 21, who sits on the immediate right of G.
  • G neither sits adjacent to the one who likes 24 nor sits at corner of the table.
  • The one who likes 21 neither sits adjacent to F nor sits adjacent to H.

Since, K doesn’t like odd number, thus in case (1a) C sits second to the right of H, in case (1b) C sits on the immediate left of H, in case (2b) C sits on the immediate left of K, case (2a) is not valid.

  • Sum of numbers liked by B and D is twice the number liked by K.

Since, only such combinations are (13, 19, 16), (14, 24, 19), (27, 21, 24) & (32, 16, 24).

  • Sum of the numbers liked by F and C is equal to the number liked by B.

Since, only such combinations are (13, 14, 27) & (13, 19, 32).

Also, we clearly, know that H likes 32, thus B must like 27.

Thus, D must like 21 and K likes 24.

  • One person sits between D and B, who neither sits adjacent to F nor sits at corner.
  • B sits second to the right of the one who likes 19.

That means, in case (1a) B sits on the immediate left of H, case (1b) & case (2b) are not valid.

Based on above given information we have:

Case 1(b) gets eliminated as One person sits between D and B, who neither sits adjacent to F nor sits at corner.

case 2(a) will get eliminated as One person sits between D and B, who neither sits adjacent to F nor sits at corner.)

case 2(b) will get eliminated as B sits second to the right of the one who likes 19. 19 cannot be placed anywhere in case 2(b). So it will get eliminated.)

Again, we have:

Since, F likes prime number, thus the only remaining prime number is 13.

  • Two persons sit between R and the one who likes a number which is a perfect square.

That means, R must like 19 and G likes 16.

Since, the only remaining number is 14, thus C likes 14.

Based on above given information we have final arrangements as follows:

1) Answer: A

2) Answer-B

3) Answer: D

4) Answer: C

Directions (5-8) :

Logic

1) Smallest odd numbers on the right end and smallest even numbers on the left end. Position of symbols unchanged.

2) After completing the steps, add 1 to even and subtract 1 from odd numbers.

3) At last arrange the numbers in the ascending order.

Input: * 5 $ 9 / 8 4 © 3 + 2 = 6 %

Step I: 2 * 5 $ 9 / 8 4 ©+  = 6 % 3

Step II: 2 4 * $ 9 / 8 ©+  = 6 % 3 5

Step III: 2 4 6 * $ / 8 ©+  =  % 3 5 9

Step IV: 2 4 6 8 * $ /  ©+  =  % 3 5 9

Step V: 3 5 7 9 * $ /  ©+  =  %  2 4 8

Step VI: 2 3 5 7 9 * $ /  ©+  =  %   4 8

Step VII: 2 3 4 5 7 9 * $ /  ©+  =  % 8

Step VIII:2 3 4 5 7 8 9 * $ /  ©+  =  %

5) Answer: D

6) Answer: A

7) Answer: C

8) Answer-D

Directions (9-10) :

9) Answer: A

Option a is the correct answer. As we see in the statement, The chairman of the company urged to all employees not making long personal calls because it may be affected in your productivity. In assumption I, Employees should respond positively to the chairman’s appeal because it will give positive results in future. The assumption I is implicit while Assumption has a negative impact which not implicit.

10) Answer: E

A decision is taken if it is felt that the decision would be an acceptance among most of the people. Hence, Assumption I is implicit. Assumption II is also implicit as the reason behind need
