Question 1
3 / -1

Direction: In the given matrix which option will replace the question mark.

15 12 11

21 14 51

37 28 ?

A
47

B
98

C
83

D
76

Solution

The logic follows here is:

From the first row :

15 12 11

15 - 12 = 3

32+ 2 = 9 + 2 = 11

From second row:

21 14 51

21 - 14 = 7

72+ 2 = 49 + 2 = 51

From Third row:

37 28 83

37 - 28 = 9

92 + 2 = 81 + 2 = 83

So, that Third column third row is "83".
Question 2
3 / -1

Direction: Select the number that will come next in the following series.

120, 60, 60, 90, 180, ?

A
450

B
360

C
420

D
540

Solution

The pattern followed here is:

Therefore, 450 is the correct answer.
Question 3
3 / -1

Which of the following answer figure completes the series of the question figure?

A

B

C

D

Solution

The pattern followed here is:

Step 1: Add a line in extreme right end in clockwise direction.

Step 2: Remove a line in extreme left end in clockwise direction.

Thus if we compare Fig. 1 and Fig. 2 we will observe the above case.

And so on comparing every alternate figure.

Thus when we Follow the above two steps for the problem figure, we get,

Thus the complete series will be
Question 4
3 / -1

Direction: Select a figure from amongst the four alternatives that when placed in the blank space (?) of figure X will complete the pattern. (Rotation is not allowed).

A

B

C

D

Solution

The figure from amongst the four alternatives that when placed in the blank space (?) of figure X will complete

the pattern when rotation is not allowed is shown below:
Question 5

702, 350, 174, 86, 42, ?

A
15

B
12

C
17

D
20

Solution

The pattern followed is,
Question 6
3 / -1

Direction: Select the figure that will come next in the following series.

A

B

C

D

Solution

The pattern followed here is,

From box 1 to box 2 , All the symbols move one position in an anticlockwise direction.

From box 2 to box 3 , the middle symbol along the sides interchange their position with the symbol in front of them, and symbols along the corners interchange their position diagonally.

Again From box 3 to box 4 , All the symbols move one position in an anticlockwise direction.

So In the next step, the middle symbol along the sides interchange their position with the symbol in front of them, and symbols along the corners interchange their position diagonally.

From box 4 to box 5 , we get

The figure which will come next is,
Question 7
3 / -1

Direction: In the following question, three statements are given followed by three conclusions I, II and III. You have to consider the given statements to be true even, if they seem to be at variance with commonly known facts. Read all the conclusions and decide which of the following logically follows from the given statements disregarding the commonly known facts.

Statements:

All Motors are Iron.

All Iron are Cheap.

Some Cheap are not Products.

Conclusion:

I. All Products are Iron.

II. Some Iron are Motors.

III. Some Products are not Iron.

A
Only II follows

B
Either II or III and I follows

C
Both I and III follows

D
Either I or III and II follows

Solution

The logic follows here is:

The least possible Venn diagram for the given statements is as follows,

Conclusion:

I. All Products are Iron $\rightarrow$ False (No direct relation is given hence, False)

II. Some Iron are Motors $\rightarrow$ True (All Motors are Iron so, Some Iron are Motors is True)

III. Some Products are not Iron $\rightarrow$ False (No direct relation given hence, False)

Conclusion I and III are complimentary pairs.

So, Conclusions Either I or III and II follows.
Question 8

86 : 62 : : 49 : ?

A
29

B
49

C
35

D
42

Solution

Here, the pattern is,

86= (8 × 6) + (8 + 6) = 48 + 14 = 62

Similarly,

49= (4 × 9) + (4 + 9) = 36 + 13 = 49

Thus, 49 is related to 49.
Question 9
3 / -1

$62 : 155 :: 58 : ?$

A
131

B
148

C
145

D
256

Solution

The pattern here is:

$62 = \frac{62}{2} = 31$

$31 \times 5 = 155$

Similarly,

$58 = \frac{58}{2} = 29$

$29 \times 5 = 145$

Thus, $58$ is related to $145$ .
