The logic follows here is:

Now,

Karan is 17 years old, has a weight of 47 kgs, and a height of 161 cms.

It is clearly mentioned in the criteria of Physical in Sub-inspector and Army recruitment about the weight and height of the candidate. Karan has a weight of 47 kgs and a height of 161 cms which is less than the criteria set for both the recruitment. Therefore, Karan neither qualifies for Physical in Sub-inspector and Army recruitment.

Hence, the correct answer is "Neither Sub-inspector nor Army recruitment".

The All four part of the the figure is identical. So after folding the 2 times of the figure, it will become figure like option C.

As Ornithologist is a specialist of Birds similarly Archealogist is a specialist of Archealogy.

The Symbol table is as follows:

1) Rajiv is the brother of Atul.

2) Atul is the son of Sonia.

Implies, Rajiv is also the son of Sonia.

3) Sonia is the sister of Sunil.

Implies, Sunil is the maternal uncle of Rajiv and Atul.

Hence, Rajiv is the "son" of Sonia.

The Logic followed here is:

The third number = The First number × (second number ÷ 2)

In Row 1:- 10, 4, 20

The third number = 10 × (4 ÷ 2)

= 10 × 2 = 20

In Row 2:- 15, 8, 60

The third number = 15 × (8 ÷ 2)

= 15 × 4 = 60

Similarly,

In Row 3:- 25, 8, ?

The third number = 25 × (8 ÷ 2)

? = 25 × 4 = 100

Hence, the correct answer is "100".

The most common pattern asked in exams are based on:

• It could be the sum of two numbers divided by a constant
• It could be the average of numbers.
• It could be in the form of alphabets, where alphabets are increased by constant or increased by the square of numbers or increased by prime numbers.
• It could be the difference of product of two diametrically opposite numbers.
• It could be the difference in the sum of adjacent numbers.
• The difference of the numbers could be in the pattern 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the pattern 12 ± 1, 22 ± 1, and so on.
• Numbers could be 12, 22, 32, and so on or 13, 23, 33, and so on.
• The difference could be prime numbers or the difference could be the square of prime numbers.
• The difference could be in the form of N2 ± N or N3 ± N.
• The difference could be in the form of ×N + N or ×2 + 1, ×2 + 2, ×2 + 3, and so on.
• The difference could be in the form of ×2 ± 1 alternatively.
• Numbers could be ×1, ×2, ×3, and so on. 

Hence, the person will be allowed to write a written test.

Venn diagram according to the given information is:

Guava, Mangoes, Fruits

As Mangoes and guava both are fruits, so they will come inside the fruits.

But,

Individually both the guava and mangoes are different fruits so there will be no intersection or shared part, so they will come as a separate circle inside the fruits.

Hence, the correct answer is "Option 4".

The logic follows here is:

Pattern: Letter increased by +1, +2, +3, +4, +5, +6 and so on.

Similarly,

Hence, "FZDQURL" is the correct answer.

As 'Architect' makes 'Building' similarly 'Sculptor' makes 'Statue'.

As opposite meaning of peace is chaos similarly opposite meaning of creation is destruction.

As per the given information;

Distance between S and P = √(PQ² + QS²)
SP = √(6² + 8²)
SP = √(36 + 64)
SP = √100
SP = 10 km
Hence, S is 10 km in South-East with respect to P.

From the common explanation, we get T sits immediate right of P.

Hence, Option B is correct.

Final Arrangement:

Common Explanation:

References:

M is sitting fourth to the right of N.

P is sitting second to the left of N.

Inferences:

From the above reference, we get the following arrangements:

References:

Q is sitting third to the right of S.

Inferences:

From the above reference, we get two different cases:

Case 1:

Case 2:

References:

S is not sitting beside P.

T is sitting second to the left of O.

O is not sitting beside M.

Inferences:

So, from this case 1 will be eliminated as S is not sitting beside P.

Thus, the final arrangement,

If you fold the paper from left to right from dotted line, the left part figure will go in opposite direction. Please take a transparent paper and draw a similar figure and fold it.

In this figure counting the squares and we get the 27 squares.

As Tiger is found in Forest similarly Otter is found in the water.

Persons: A, B, C, D, E and F

1) E is sitting immediate left to the B.

2) A is sitting fourth right to the B.

3) F is sitting between A and D.

4) Final Sitting arrangement.

Hence, “C” is sitting immediate left to the D.

From statement I alone, we don’t get the answer.

From statement II alone, Q is sitting 2nd to the left of T. T is facing P. The number of friends sitting between P and Q is same as the number of friends sitting between P and W.

From statement II alone, we don’t get the answer.

Combining both statement I and II, we get,

From statements I and II together, we don’t get the answer.

Hence, option ‘D’ is correct.
