Thus, Rajat is applicable for both the clauses, but the age is non-negotiable factor , therefore will be referred to the CEO's desk.

Hence, "Option 2" is the correct answer.

Given: A bag has 4 fair coins (1 head 1 tail) and 4 double-headed coins. A coin is drawn and flipped 3 times all heads. 

So, probability of choosing a fair coin → \(\frac{4}{8}\) = \(\frac{1}{2}\)

And, probability of choosing a double-headed coin → \(\frac{4}{8}\) = \(\frac{1}{2}\)

If the coin is fair, probability of 3 heads is → \((\frac{1}{2})^3\) = \(\frac{1}{8}\)

If the coin is double-headed, probability of 3 heads is → 1

So, probability of 3 heads will be P (3H) → (1 × \(\frac{1}{2}\)) + (\(\frac{1}{8}\) × \(\frac{1}{2}\))

→ \(\frac{1}{2}\) + \(\frac{1}{16}\) = \(\frac{9}{16}\)

So, probability of double-headed will be → (1 × \(\frac{1}{2}\)) = \(\frac{1}{2}\)

Thus, the required probability will be → \(\frac{1}{2} \over \frac{9}{16}\) = \(\frac{8}{9}\)

Hence, "Option 2" is the correct answer.

The logic followed here is:

Here, 'a' is '4'

5a = 20 → 5 × 4 = 20

And,

7a = 28 → 7 × 4 = 28

Similarly,

9a = ? → 9 × 4 = 36

Hence, "Option 3" is the correct answer.

According to the question, after interchanging the given two signs and numbers respectively:

So, checking each option one by one:

Option 1) Signs × and-, Numbers 5 and 4

10 + 4 - 5 × 2 = 19 ⇒ 10 + 5 × 4 - 2 = 19

⇒ 10 + 5 × 4 - 2 = 19

⇒ 10 + 20 - 2 = 19

⇒ 30 - 2 = 19

⇒ 28 ≠ 19 (LHS ≠ RHS)

Option 2) Signs - and +, Numbers 10 and 5

10 + 4 - 5 × 2 = 19 ⇒ 5 - 4 + 10 × 2 = 19

⇒ 5 - 4 + 10 × 2 = 19

⇒ 5 + 20 - 4 = 19

⇒ 25 - 4 = 19

⇒ 21 ≠ 19 (LHS ≠ RHS)

Option 3) Signs × and +, Numbers 2 and 4

10 + 4 - 5 × 2 = 19 ⇒ 10 × 2 - 5 + 4 = 19

⇒ 10 × 2 - 5 + 4 = 19

⇒ 20 + 4 - 5 = 19

⇒ 24 - 5 = 19

⇒ 19 = 19 (LHS = RHS)

Option 4) Signs + and -, Numbers 10 and 2

10 + 4 - 5 × 2 = 19 ⇒ 2 - 4 + 5 × 10 = 19

⇒ 2 - 4 + 5 × 10 = 19

⇒ 2 + 50 - 4 = 19

⇒ 52 - 4 = 19

⇒ 48 ≠ 19 (LHS ≠ RHS)

Hence, "Option 3" is the correct answer.

The logic followed here is:

Blue, Green and Red are different types of colors but Smooth is an adjective describing a texture, not a color.

Hence, "Option 1" is the correct answer.

Decoding signs:

Given: 150 × 25 - 5 ÷ 10 + 2 = ?

150 × 25 - 5 ÷ 10 + 2 = ? ⇒ 150 + 25 ÷ 5 - 10 × 2 = ?

⇒ 150 + 25 ÷ 5 - 10 × 2 = ?

⇒ 150 + 5 - 10 × 2 = ?

⇒ 150 + 5 - 20 = ?

⇒ 155 - 20 = ?

⇒ 135 = ?

Hence, "Option 3" is the correct answer.

The logic followed here is:

21463: 43685 → 21463 + 22222 = 43685

Similarly,

38521:? → 38521 + 22222 = 60743

Hence, "Option 4" is the correct answer.

The folding the paper cutting along the lines to make a cubical box is shown below:

⇒ As the alternate positions become opposite to each other, the remaining two faces become opposite to each other.

So, opposite pairs are:

 →

 →

→

So, each checking option one by one:

Option 1)

⇒  Cannot be made because 

 is adjacent to 

.

Option 2) 

⇒ Cannot be made because 

 is adjacent to

.

Option 3) 

⇒ Can be made because all are the opposite sides..

Option 4) 

⇒ Cannot be made because 

 is adjacent to 

.

Hence, "Option 3" is the correct answer.

The logic followed here is: 

Option 1) 

→ The number of shaded elements are equal to number of non-shaded elements.

Option 2) 

→ The number of shaded elements are equal to number of non-shaded elements.

Option 3)

→ The number of shaded elements are equal to number of non-shaded elements.

Option 4) 

→ The number of shaded elements are more than number of non-shaded elements.​

Hence, "Option 4" is the correct answer.

The logic followed here is:

→ The whole element rotate 90º anticlockwise and the outside facing line at the vertex face the opposite direction.

Similarly,

→ The whole element rotate 90º anticlockwise and the outside facing line at the vertex face the opposite direction.

Hence, "Option 3" is the correct answer.

The number of triangles in the given figure is shown below:

Thus, there are a total of 27 triangles.

Hence, "Option 1" is the correct answer.

Alternate Method

1) Number of triangles = \({n(n + 2)(2n + 1)\over 8}\) , Where; n = 4 (number of triangles at the baseline)

= \({4(4 + 2)(2 \times 4 + 1)\over 8}\)

= \({4(6)(8 + 1)\over 8}\)

= \({4 \times 6 \times 9\over 8}\)

= 27

The logic followed here is digit-wise addition of +2 to each digit of the number:

14825 : 36047 

→ 1 + 2 = 3, 4 + 2 = 6, 8 + 2 = 10 (unit digit = 0), 2 + 2 = 4, 5 + 2 = 7

Similarly,

27416 : ?  

→ 2 + 2 = 4, 7 + 2 = 9, 4 + 2 = 6, 1 + 2 = 3, 6 + 2 = 8 

So, 27416 ⇒ 49638

Hence, "Option 1" is the correct answer.

The logic followed here is:
