11. Consider the following matrix: [2013-II]

 

What is the number at 'X' in the above matrix?

Correct Answer: (c)
Solution:Consider 2โฟแตˆ element in each row. Sum up the digits of each number.
3 + 7 + 0 = 10
2 + 2 + 4 = 8
7 + 3 + 0 = 10
Now redraw the table agains:

12. Examine the following three figures in which the numbers follow a specific pattern: [2013-II]

The missing number (?) in the third figure above is

Correct Answer: (b) 16
Solution:Observe the first two figures carefully:

Hence for the third figure,

13. A cube has six numbers marked 1, 2, 3, 4, 5 and 6 on its faces. [2013-II]

Three views of the cube are shown below:

What possible numbers can exist on the two faces marked A and B, respectively on the cube?

Correct Answer: (a) 2 and 3
Solution:When we opened the cube

Now, (A) and (B), two possible numbers can exist on two faces are 2 and 3.

14. Consider the following figures: [2013-II]

Which one of the following figures would logically come in the 7th position indicated above by a question mark?

Correct Answer: (d)
Solution:From fig. (1) to (2), all arrows are moving clockwise direction. From fig. (2) to (3), all arrows are moving anti-clockwise direction. From (3) to (4), one arrow is in reversed direction and others are moving clockwise. Same pattern is followed for the rest.

15. Consider the following statements: [2013-II]

(i) A primary group is relatively smaller in size.

(ii) Intimacy is an essential characteristic of a primary group.

(iii) A family may be an example of a primary group. In the light of the above statements,

which one of the following is true?

Five cities P, Q, R, S and T are connected by different modes of transport as follows:

P and Q are connected by boat as well as rail.

S and R connected by bus and boat.

Q and T are connected by air only.

P and R are connected by boat only.

T and R are connected by rail and bus.

Correct Answer: (d) Members of a primary group know each other intimately.
Solution:As intimacy is an essential characteristic of a primary group, members of a primary group know each other intimately.

16. Which mode of transport would help one to reach R starting from Q, but without changing the mode of transport?

Correct Answer: (a) Boat
Solution:Looking at the above diagram, we can see that we have only one route i.e. Q โ†’ P โ†’ R which has a single mode of transportation i.e. boat.

17. If a person visits each of the places starting from P and gets back to P, which of the following places must he visit twice?

Correct Answer: (b) R
Solution:

With the given options, we have the following possibilities:

P โ†’ Q โ†’ T โ†’ R โ†’ S โ†’ R โ†’ P

P โ†’ R โ†’ S โ†’ R โ†’ T โ†’ Q โ†’ P

In both the cases, R should be visited twice as S is connected only to R.

18. Which one of the following pairs of cities is connected by any of the routes directly without going through any other city?

Correct Answer: (d) None of these
Solution:None of the cities in the given options directly connected. Therefore, option (d) is the correct answer.

19. Between which two cities among the pairs of cities given below are there maximum travel options available? [2013-II]

Correct Answer: (a) Q & S
Solution:

Going by options:
Q and S: Q โ†’ T โ†’ R โ†’ S

Hence, all the options are available. Therefore, option (a) is the correct answer.

20. If Y is selected and B is rejected, the team will consist of which one of the following groups?

Correct Answer: (b) A, C, X and Y
Solution:If Y is selected, W shall not be selected. So options (a) and (d) are out. As C cannot play with Z, option (c) is also out. Hence, (b) is the correct answer.
