Hence, the correct answer is "Option 4".

Correct Option - 2

BODMAS Table:

Now, checking each option one by one:

1. 10 + 2 x 2 - 4 = 10

After replacing the symbols by their meaning, we get:

⇒ 10 − 2 + 2 ÷ 4 = 10

= 10 − 2 + 0.5 = 10

= 10.5 - 2 = 10

= 8.5 ≠ 10

⇒ LHS ≠ RHS

2. 14 ÷ 2 - 2 + 4 = 10

After replacing the symbols by their meaning, we get:

⇒ 14 × 2 ÷ 2 − 4 = 10

⇒ 14 × 1 − 4 = 10

⇒  14 − 4 = 10

⇒ 10 = 10

⇒ LHS = RHS

3. 12 x 2 + 4 - 1 = 27

After replacing the symbols by their meaning, we get:

⇒ 12 + 2 − 4 ÷ 1 = 27

⇒ 12 + 2 − 4 = 27

⇒ 14 − 4 = 27

⇒ 10 ≠ 27

⇒ LHS ≠ RHS

4. 8 + 4 - 2 x 1 = 10

After replacing the symbols by their meaning, we get:

⇒ 8 − 4 ÷ 2 + 1 = 10

⇒ 8 − 2 + 1 = 10

⇒ 9 − 2 = 10

⇒ 7 ≠ 10

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 2".

Statements:

All metals are elements.

Some elements are gases.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some metals are gases. - False (No definite relation given between metal and gases, so it can be possible only)

II. All gases beig elements is a possibility. - True (No definite relation given between metal and gases, so it can be possible only)

Hence, the correct answer is "Option 1".

Correct Option - 4

BODMAS Table:

Given equation:  4 – 2 × 3 + 6 = ?

After replacing the symbols by their meaning, we get:

⇒ 4 ÷ 2 + 3 × 6 = ?

⇒ 2 + 3 × 6 = ?

⇒ 2 + 18 = ?

⇒ 20 = ?

Hence, the correct answer is "Option 4".

Correct Option - 3

Given: The ratio of two numbers is 4:5 and their sum is 180.

Let the numbers be 4a and 5a.

According to question:

⇒ 4a + 5a = 180

⇒ 9a = 180

⇒ a = 180 ÷ 9

⇒ a = 20

Thus, the numbers are:

4a = 4 × 20 = 80

5a = 5 × 20 = 100

Hence, the correct answer is "Option 3".

Given word: T E C H N O L O G Y

2^nd letter = E

7^th letter = L

Letters between them (excluding 2^nd and 7^th):

C, H, N, O

Now, count consonants:

C 

H 

N 

O (vowel)

So,Total consonants = 3

Hence, the correct answer is "Option 1".

The address given in the problem is,

56/A, Greenwood Villa,Salt Lake City, Kolkata,West Bengal - 700091

Let's match this address with the given options one by one to figure out which one is exactly the same.

So, the address that is exactly the same as the given address is in option (3).

Hence, the correct option is "option (3)".

The logic followed here is:

B is the daughter of C.

 

So, A is the Son of C.

Hence, the correct answer is "Option 2".

Family Chart:

Given:

B is the sister of A.

A is the brother of C.

C is the daughter of D.

 

So, B is the Daughter of D.

Hence, the correct answer is "Option 1".

The logic followed here is:

thus, "50" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

Logic: Numbers which are divisible by 2 (Even numbers).

Now, checking the options:

Option 1) 2, 4, 6, 8

⇒ 2 is divisible by 2

⇒ 4 is divisible by 2

⇒ 6 is divisible by 2

⇒ 8 is divisible by 2

(All numbers are even numbers.)

Option 2) 3, 6, 9, 11

⇒ 3 is not divisible by 2

⇒ 6 is divisible by 2

⇒ 9 is not divisible by 2

⇒ 11 is not divisible by 2

(Not all are even.)

Option 3) 5, 10, 13, 21

⇒ 5 is not divisible by 2

⇒ 10 is divisible by 2

⇒ 13 is not divisible by 2

⇒ 21 is not divisible by 2

(Not all are even.)

Option 4) 7, 14, 26, 38

⇒ 7 is not divisible by 2

⇒ 14 is divisible by 2

⇒ 26 is divisible by 2

⇒ 38 is divisible by 2

(Not all are even.)

Hence, the correct answer is "Option 1".

The logic followed here is:

thus, "190" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

Given Statement: Despite the unpredictability of future technologies, regulatory frameworks must evolve to preempt ethical crises.

Now, 

Assumptions:

I. Unregulated technological growth can cause ethical dilemmas → Implicit (If technology does not cause ethical problems, there would be no need to evolve regulations to prevent them).

II. Ethical standards are often retrofitted to existing technology → Implicit (The statement suggests regulations should evolve before crises occur, implying that normally ethical rules are applied after technology appears).

III. Regulatory systems can always accurately predict technological outcomes → **Not implicit (**The statement actually says future technologies are unpredictable).

Only I and II are implicit

Hence, the correct answer is "Option 1".

Given Statement:

The education ministry has made moral education compulsory in schools.

Conclusion I: Students must attend moral education classes → Follow (If a subject is compulsory in schools, students studying in those schools must attend those classes).

Conclusion II: Schools were not offering moral education earlier → Does not follow ( The statement only says it is now compulsory. It does not state whether schools offered it earlier or not.Some schools may already have been teaching it**).**

Hence, only conclusion I follows.

Hence, the correct answer is "Option 1".

The correct chronological order (based on Age/History) is:

5. Stone Age
6. Bronze Age
7. Iron Age
8. Industrial Revolution
9. Information Age

Thus, The correct order is '5, 2, 4, 1, 3'.

Hence, the correct answer is "Option (1)".

The logic followed here is:

Logic: Tool and its primary function.

Given, Needle : Sew

⇒ A needle is used to sew.

Now, applying the same logic:

Keyboard : ?

⇒ A keyboard is used to type.

Now, checking the options:

Option 1) Draw

⇒ A keyboard is not used to draw.

Option 2) Type

⇒ A keyboard is used to type.

Option 3) Write

⇒ Writing is done using a pen or pencil, not directly by a keyboard.

Option 4) Print

⇒ Printing is done using a printer.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: Words having similar meaning (related to complexity).

Now, checking the words:

Complex → means complicated

Intricate → means very detailed and complicated

Sophisticated → means complex or advanced

Elaborate → means detailed and complicated

Simple → means easy or not complicated

Here, all words except "Simple" indicate something complicated or complex.

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: Units of temperature.

Now, checking the units:

Kelvin → Unit of temperature

Celsius → Unit of temperature

Fahrenheit → Unit of temperature

Rankine → Unit of temperature

Joule → Unit of energy

Here, all except "Joule" are units of temperature.

Hence, the correct answer is "Option 4".

The logic followed here is:

Logic: The 1^st and 2^nd letters are interchanged, the 3^rd and 4^th letters are interchanged, and the last three letters are rearranged as 7^th, 5^th, 6^th.

Given, M E T A P H O R

After rearrangement:

1^st and 2^nd → E M

3^rd and 4^th → A T

Last four letters P H O R → H P R O

So, METAPHOR : EMATHPRO

Now, applying the same logic:

N O R M A L

1^st and 2^nd → O N

3^rd and 4^th → M R

Last two letters A L → L A

So, NORMAL : O N M R L A

Hence, the correct answer is "Option 3".
