SSC Selection Post Mock Test - 3 - SSC Selection Post MCQ

The logic followed here is:

Hence, '77' is the correct answer,

The least possible Venn diagram for the given statements is as below:

Conclusions: 
1. No K is J → False (It is possible but not definite).
2. Some J are not T → True (As no T is J then some J is not T is also a definite conclusion).
3. Some R are J → False (It is possible but not definite).
Hence, the correct answer is "Only conclusion II follows".

Using options and making required changes:
8 ÷ 4 - 6 + 9 × 3 = 10
1) × and ÷
⇒ 8 × 4 - 6 + 9 ÷ 3 = 10
⇒ 32 - 6 + 3 = 10
⇒ 29 = 10 (INCORRECT)
2) - and ×
⇒ 8 ÷ 4 × 6 + 9 - 3 = 10
⇒ 12 + 9 - 3 = 10
⇒ 18 = 10 (INCORRECT)
3) ÷ and -
⇒ 8 - 4 ÷ 6 + 9 × 3 = 10
⇒ 8 - (2/3) + 27 = 10
⇒ (-59/3) = 10 (INCORRECT)
4) + and ÷
⇒ 8 + 4 - 6 ÷ 9 × 3 = 10
⇒ 8 + 4 - 2 = 10
⇒ 10 = 10 (CORRECT)
Hence, the correct answer is "Option (4)".

The positional value of the English alphabet is given below:

Logic:
Letters are changed to their opposite letters.
'CLOWN' is written as 'XOLDM'

And,
'TOWEL' is written as 'GLDVO'

Similarly, 
'CLOTH' is written as '?'

Hence, the code for CLOTH is XOLGS.

The figure that completes the pattern of the given figure is shown below:

Hence, 'option 3' is the correct answer.

The logic follows here is,
The arrangement of all the given words in the order in which they appear in an English dictionary is as shown below:
The three letters N, A and R are common in all words, so we will start arranging the word from the fourth letter as per alphabetical order.
1. Narcoanalyses
2. Narcoanalysis
3. Narcotization
5. Narrativizing
4. Narrowcasting
Hence, the correct answer is "13254".

Here, we need to find the pattern
The logic here is: The code language is the square of the total number of letters in a word.
So, for the word ACTION = 6 letters = 6² = 36
And, for the word PIZZA = 5 letters = 5² = 25
Thus, for the word GALLERY = 7 letters = 7² = 49
Hence, the code language is 49 for the given word.

The mirror image of the given figure when the mirror is placed at MN is shown below: 

The word ends with the letter P. So, the mirror image will start with mirror image P (q) however, options 2,3,4 are eliminated.
Hence, "Option 1" is the correct answer.

The ratio of the ages:
Child : Father : Grandfather = 1 : 5 : 9
Three years hence, the age of the child is = 10 years
The age of child in present time = (10 - 3) = 7 years
As per the given ratio:
⇒ Child = 1 = 7 years
⇒ Present age of the grandfather = 9 = (9 × 7) = 63 years
⇒ Present age of the grandfather = 63 years
Hence, the correct answer is "Option (2)".

The logic followed here is :- Difference between the first two and the last two letter's position value according to English alphabetic series is equal.
​So,

• Option - (1) : SQO
  ​
• Option - (2) : YWU
  ​
• Option - (3) : MKI
  ​
• Option - (4) : GED
  ​

Here, Only 'GED' difference between first two and last two letter's position value according to English alphabetic series is not equal.
Hence, the correct answer is "GED".

Given :

Statement given : W # Q @ T & Y @ M % K
So,

• W # Q → W is the mother of Q.
  
• Q @ T → Q is the son of T.
  
• T & Y → T is the brother of Y.
  
• Y @ M → Y is the son of M.
  
• M % K → M is the wife of K.
  ​

Thus, according to the final family tree K is the father-in-law of W.
Hence, "Father-in-law" is the correct answer.

The table shows the place value of the alphabet from A to Z and Z to A.

The logic followed here is:
Now, JUG is coded as 38 
 
WATER is coded as 67

Similarly,  GLASS be coded as 
Therefore, GLASS be coded as "58".
Hence, the correct answer is "Option (1)"

The least possible venn diagram for the above statements is shown below.

For conclusions:
I. Some wickets are bats → True (As, some bats are wickets, some wickets are bats. Hence, it is true)
II.  All balls are wickets → False (As, All balls are bats, some bats are wickets, no relation given between balls and wickets. Hence, it is false)
Hence, "If only conclusion I follows" is the correct answer.

The number of triangles can be calculated by naming each corner as follows:

We can observe the following triangles:
EGF, BCD, ABC, GFD, BED, EFD
Thus, the total number of triangles is 6.
Hence, the correct answer is 6.

According to the given condition, we have to select a figure in which a shaded small circle is present between two parallel lines and there should be no line passing through the circle.
The figure given below has the given question figure embedded in it.

Hence, this is the correct answer.

We know that when a mirror is placed at the bottom side of the figure, then the left and right parts of the image remain the same, while the top and bottom sides of the image will be interchanged in the mirror image i.e. the figure is flipped vertically.
So, the shaded circle will come in the bottom-left part of the circle.
Hence, the correct answer is:
 

We are given the following information in the problem:

19 D 3 A 11 B 12 C 132  
= 19 – 3 + 11 × 12 ÷ 132 
= 19− 3 + 11 x (12)/132
= 19 - 3 + 1 = 17
Hence, the correct answer is 17.

In dictionary words are written according to the alphabet series.
All letters are starting with ‘’C’’, so we will check the second letter of each word and try to write the words in the sequence.
Crane
Creep
Crest
Crow
Gown

The place value of the letters are given below:

In the given series, we can observe that the letters are decreasing by a positional value of 2.
For example, X −2 = V, etc.

Hence, the correct answer is T.

8 + 5 = 13  
5 + 5 = 10  
7 + 5 = 12  
9 + 5 = 14 ≠ 16
We can observe that second number of each group is equal to the sum of first number and 5. Thus, the odd pair is (9 −16).

According to the given condition, the garment is an item of clothing.
So, trouser and shirt are garments, but trouser is not a shirt, and vice-versa.
Thus, the correct relationship between Trouser, Shirt, and Garment, is:

Hence, this is the correct answer.

We know that
12² = 144
We can observe that second number of first part is square of the first number.
Therefore,
? = 14² = 196

We need to find which word cannot be formed using the letters from the word “SINGULAR ”.
No, extra letter should be used in the word's formation.
"RAISE" cannot be formed, as the letter ‘’E’’ is not present in the word SINGULAR.

Following symbols are used to solve the blood relation problem:

Draw the relationship diagram from the given relationship.

Clearly, C is the nephew of E.

Write the positional number of all the alphabets as shown below:

The pattern followed by the letters is,

The positional values of the letters of the word SPROUT is increased by 5.
So, the answer will follow the same pattern and the correct answer is,

Thus, “XYJFR” is the correct answer.

Given:
Days taken by A to complete the work = 6 days
Efficiency of B = 25% more efficient than A
Calculation:
⇒ Work done by A in one day = 1/6
⇒ According to the question,
⇒ Number of days B would take to complete the work = 1/6 + 25% of 1/6
⇒ Number of days taken by B to complete the work = 
⇒ Time in which B can complete the work = 24/5 = 4(4/5) days
∴  The time B would take to finish the work is 4(4/5) days.

Given:

Formula used:
(a + b)² - (a - b)² = 4ab
Calculations:
(a + b)² - (a - b)² 
⇒ a² + b² + 2ab - {a² + b² - 2ab}
⇒ 2ab + 2ab = 4ab
Now, 

∴ The answer is 4.

Given:
20 men work in 6 hours for 7 days.
Formula used: 
M₁ × D₁ × H₁ = M₂ × D₂ × H₂
Where, M = Men , D= Days , H = Hours
Calculation:
Here,
M₁ = 20 , H₁ = 6 hours , D₁ = 7 Days
M₂ = 10, D₂ = 12 days , H₂ = ?
As we know,
M₁ × D₁ × H₁  =  M₂ × D₂ × H₂
⇒ 20 × 7 × 6 = 10 × 12 × H₂
⇒ H₂  =  7 hours
Hence, 7 hours is taken by 10 men to complete the same work.

Given:-
Radius ratio =  2 : 1 and Height ratio = 1 : 2
Formula used:-
Volume of cylinder = πr²h
Calculation:- 
Let the radius and height of cylinder-1 and cylinder-2 be r , h  and R , H respectively
As given,
r : R = 2 : 1
h : H = 1 : 2
Let their volumes be V₁ and V₂, So

On reducing π from numerator and denominator then by substituting the values of radius and heights,

The ratio of volumes of two cylinders is 2 : 1.

Given:
Amount = Rs. 112, rate = 4%, time = 3 years.
Formula used:

Amount = principal + SI
Amount = principal + 
Amount = principal 
Calculations:
112 = principle 
112 = principle 
112 = principle × (28/25)
Principle = 
Principle = 4 × 25 = 100
∴ The answer is Rs. 100.
