Practice Test: Logical Reasoning - 11 - SSC CGL MCQ

Both professionals and Chartered Accountants can be female, and all chartered accountants are professionals, hence the second diagram best describes above relationship.

All natural numbers are integers and all integers are complex numbers.

Thus, the third figure represents above relationship.

All fathers are definitely males, and the engineers can be either males or fathers.

Thus, the third figure best represents the above relationship.

When the six squares are folded, we get :

3 lies opposite black dot

W lies opposite slanted 1

1 lies opposite white dot

Thus, Ans - (a)

All staff members and managers are workers, and some staff members are also managers, hence the second figure best describes above relationship.

The question figure is embedded in the following figure in blue colour.

In the question figure, the tree is on the left of the house, => It will appear on the right in the mirror

=> (d) is eliminated.

The flag is facing east in the figure, thus it will face west in mirror.

=> (b) is eliminated.

There is a small dot in the middle of the flag which will not change in the mirror, which is present in option (c)

Ans - (c)

Since, a vertical mirror is placed, thus the top and bottom positions will remain same, while the left and right positions will be swapped.

The black triangle at the top left will appear at top right and thus the second and third figure will be eliminated.

Now, the position of lines in the top right triangle will also change. The lines are parallel to the side of the triangle that does not contain any shaded regions. The mirror image should retain the same relationship. Therefore, option D is the right answer. 

By folding the squares, B will be the base and E will become the top of the cube.

Similarly, O will face N and D will face A.

Thus, ADE and BNO cannot be the adjacent sides of the cube.

From the first 2 figures, it is evident that +, ^, * and % will not face '$' as they all are adjacent to it.

From the third figure, there is only one remaining figure which will face '$' that is = '&'

Smaller triangles = 6

Triangles formed by combination of 3 triangles = 2

Larger triangles (at the diagonals) = 4

Thus, total triangles = 6 + 2 + 4 = 12

=> Ans - (c)

People who study only Mathematics and Chemistry = 6

People who study only Chemistry and Physics = 12

People who study only Mathematics and Physics = 5

=> People who can study only 2 subjects = 6 + 12 + 5 = 23

=> Ans - (b)

As seen form the middle point, the 8 lines originating are at equal intervals

=> (a) is eliminated

The diagonal arrow is facing top left, thus in the mirror it will ace top right.

=> (b) is eliminated.

Now, if we look at the vertical line, the top triangle is facing east and the bottom one is facing west, => in the mirror the top will face west and the bottom will face east

=> (d) is eliminated

Ans - (c)

In the question figure, there are two outer squares which are given in all the options, if we look inside it, we find :

two squares of different length, one black dot, and four straight lines of length less than the smaller square of the two.

Thus we need: 12 straight lines(4 * 2 + 4) in group of 3( each group of different lengths) and one black dot which is clearly given in option (a)

If we complete the remaining portion in the question figure, we get :

Now, the third figure resembles the part in blue colour.

Piano and Guitar are both different types of music instruments, thus the second figure best describe their relation.

=> Ans - (b)

Both pens and pencils are part of stationary, and also pens are different from pencils.

Thus, the venn diagram that best describe above relationship is :

Ans - (c)

In the above diagram:

Triangle represents Mothers

Circle represents Teachers

Rectangle stands for Women

So, women who are both mothers and teachers, we need to find the area which consist of triangles, circles and rectangles.

Clearly 'C' represents such area.

Both leopard and lion are animals but are completely different from each other.

Thus, the third figure best describes above relationship.

=> Ans - (c)

All cities are part of a state and all states are part of a country.

Thus, the last figure perfectly describes the above relationship.

=> Ans - (d)

India can consist both black eyed people and brown haired people.

Similarly, A black eyed person can have brown hair and belong to India, and also a brown haired person can have black eyes and belong to India.

Thus, the venn diagram that best depicts above relationship is:

Milk is in liquid form, thus all milk is liquid, and pizza is neither related to milk nor liquid. Thus, the last diagram best represents the relationship among the given classes.

Surgeons are represented by = A + B + C + F + G

Mothers = A + F + H

Singers = C + D

Now, surgeons who are either mothers or singers = Surgeons ∩ mothers ∪ singers

= A, F, C

=> Ans - (b)

Weights of 4 boxes = 40, 70, 80 and 50 kilograms

(a) 240 = 40 + 50 + 70 + 80

(b) 160 = 40 + 50 + 70

(c) 200 = 50 + 70 + 80

(d) 220 = not possible

=> Ans - (d)

Weights of 4 boxes = 100, 70, 50 and 90 kilograms

(a) 310 = 50 + 70 + 90 + 100

(b) 260 = 70 + 90 + 100

(c) 230 = not possible

(d) 210 = 50 + 70 + 90

=> Ans - (c)
