Practice Test: Logical Reasoning - 14 - SSC CGL MCQ

In each row, the number at the end is obtained by multiplying the sum first two numbers with the third number.

Eg: (3 + 4) × 2 = 7 × 2 = 14

and (6 + 5) × 4 = 11 × 4 = 44

Similarly, (5 + 2) × 7 = 7 × 7 = 49

=> Ans - (c)

Correct Option: A

4 × 1 = 4,

4 × 2 = 8,

8 × 3 = 24,

24 × 4 = 96,

96 × 5 = 480,

480 × 6 = 2880,

2880 × 7 = 20160

Hence, option A is correct

The pattern followed is that the given numbers are cubes of natural numbers in increasing order.

Thus, missing number = 8³ = 512

Let number in first row be 'x' , in second row be 'y' and in third row be 'z'

The pattern followed is: x + y - 1 = z

=> The missing number = 5 + 1 - 1 = 5

Ans - (b)

In the first column, the first number is obtained by adding the other two numbers.

Eg: 87 + 15 = 102

and 45 + 44 = 89

Similarly, 50 + 25 = 75

=> Ans - (c)

No painter is a man, thus painters who are either men or vegetarians are represented by blue region = E + B

Let the heights of these towers be represented by P, S, U, I, C

Pearl Towers is taller than Sky Towers but shorter than Unity Towers, => U > P > S

Unity Towers and Cyber Towers are of same height, => C = U > P > S

Pearl Towers is shorter than Indus Towers, => I is either the tallest or the second tallest building.

Thus, Pearl towers is the second shortest.

Expression: 8 x 3 ÷ 4 + 9 - 5 = 16

(a) 8 × 4 ÷ 3 + 9 − 5 = 16

L.H.S. = 10.67 + 4 = 14.67 ≠ R.H.S.

(b) 4 × 3 ÷ 8 + 9 − 5 = 16

L.H.S. = 1.5 + 4 = 5.5 ≠ R.H.S.

(c) 8 × 5 ÷ 4 + 9 − 3 = 16

L.H.S. = 10 + 6 = 16 = R.H.S.

(d) 8 × 3 ÷ 4 + 5 − 9 = 16

L.H.S. = 6 − 4 = 2 ≠ R.H.S.

=> Ans - (c)

No painter is a man, thus painters who are either men or vegetarians are represented by blue region = E + B

=> Ans - (b)

Expression = 7 : 32 : : 28 : ?

Both the numbers on the left are multiplied by 4.

Eg: 7 × 4 = 28

Similarly, 32 × 4 = 128

=> Ans - (a)

Palaeontology is the branch of science concerned with fossil, similarly Phrenology is the study of skull.

Night, morning and evening are periods of a day, while noon is a time (12 pm).

Expression = DBU : EEZ

The pattern followed is :

Similarly, for CJH :

=> Ans - (c)

Position of number in the English alphabet series is given.

Eg = L = 12 and M = 13

Similarly, U x W = 21 × 23

=> Ans - (d)

The animals given are:

(a) Elephant

(b) Rat

(c) Not possible

(d) Cricket

=> Ans - (c)

The colour of clear sky is 'blue' and as given, 'blue' is called 'sky'.

So, the colour of clear sky is 'sky'.

Joy and delight are synonyms, which is related to happiness, similarly, the word similar in meaning to gloomy is dull.

Expression = MIKE : OGMC

The pattern followed is =

Similarly, for CIAD:

=> Ans - (a)

Let the heights of these towers be represented by P, S, U, I, C

Pearl Towers is taller than Sky Towers but shorter than Unity Towers, => U > P > S

Unity Towers and Cyber Towers are of same height, => C = U > P > S

Pearl Towers is shorter than Indus Towers, => I is either the tallest or the second tallest building.

Thus, Pearl towers is the second shortest.

=> Ans - (a)

People who like cricket = 9 , 12 , 15 , 17

People who like tennis = 8 , 15 , 17 , 21

Now, people who like both (intersection of both) = 15 + 17 = 32

=> Ans - (b)

To complete the above figure, we need a bottom left quadrant of a circle.

=> (a) & (c) are eliminated.

Now, in the top right of the quadrant, we need 2 curved lines which is seen in option (b)

To make up the question figure, we need :

two black dots, two straight lines of equal length and two curved lines

These objects are clearly given in option (b)

Bottles that are not brown are represented by blue colour = 31 + 26 + 1 = 58

=> Ans - (a)

Gulp means to drink in large mouthful, similarly rush means to go in a hurry.

It is given that all Mondays and Sundays are offs.

If a month starts with a Monday and has 31 days, then number of Mondays = 5 

But number of Sundays = 4

Thus, total off days = 4 + 5 = 9

=> Ans - (c)
