The logic followed here is:

The figure in image 2 is water image of the figure in image 1. The figure in image C of answer figure will be the water image of the figure in image 3.

Hence, image C of answer figure is the correct answer.

According to the sequence in the dictionary: 

The correct order of the given words is:

2. Arrange

1. Arrest

3. Arrogant

4. Arrow

Hence, the correct answer is "2, 1, 3, 4".

Additional Information

1. First of all, check the common letter in all.

2. Arrange them according to the alphabet they come first. 

3. When common letters are arranged, then go for the rest.

The above information can be summarized below diagram,

Therefore, the code for “was” will be “3”. 

Hence, option 4 is the correct answer.

The logic followed is:

In each next step 1 line segment is deleting from the given letter.

In figure A

The given shape is the letter "E".

In figure B

One line segment get deleted from the right end

Thus we get 

In figure C

Again the one-line segment gets deleted from the right end.

Thus we get 

Similarly,

In figure D

Again one line segment will get deleted from the previous image to obtained figure D.

Thus only one figure is satisfying the pattern.

Hence, the correct answer is "Option 2".

The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out. 

Given:

Five years ago, father's age was 5 times that of his son

After 3 years father will be 3 times as old as his son

Calculation:

Let the present age of son be x years 

Present age of father be y years 

According to the question,

Five years ago, father's age was 5 times that of his son

(y - 5) = 5 (x - 5)

⇒ y - 5 = 5x - 25 

⇒ y - 5x + 20 = 0     ---- (i)

After 3 years father will be 3 times as old as his son

(y + 3) = 3(x + 3)

⇒ y + 3 = 3x + 9

⇒ y - 3x - 6 = 0      ---- (ii)

Solving equation (i) and (ii) we get,

x = 13

∴ Present age of son is 13 years

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.

Only daughter of woman’s father is woman herself. So, the woman is person’s mother.

Let us assume 2∠A = 3∠B = 6∠C = K

Let AB be the kite and AC be the level ground
So that BC - AC.
At that point, ∠BAC = 60°and BC = 75m. Let AB = x meters.
Presently AB/BC = coses60° = 2/ √3
=> x/75 = 2/√3 => x = 150/√3 = 150 * √3/3 = 50 √3m.
∴ Length of the string = 50 √3m.

18% of x = 13.50% of y

50% of x = 37.50% of y
Hence, Option D is correct.

Hence, Option D is correct.

Either you can make a fraction from two whole numbers (denominator ≠ 0), thus a rational number. Or you can't, thus irrational.

Correct answer is D. 16.
= 

= (16)^{3/2  -  1/2}

= (16)¹

= 16.

Correct option is B. 
( 1/4-1/9 )x9/25x-8/27
5/36x9/25x-8/27
-2/135

1st term = 5
2nd term = 5 + (4*1) = 5 + 4 = 9
3rd term = 9 + (4*2) = 9 + 8 = 17
4th term = 17 + (4*3) = 17 + 12 = 29
5th term = 29 + (4*4) = 29 + 16 = 45

Thus, the missing number is 6th term = 45 + (4*5) = 45 + 20 = 65

The sequence is a combination of two series:

I. 19, 38, 114, (____)
II. 2, 3, 4

Considering Series I:
1st term = 19
2nd term = 19*2 = 38
3rd term = 38*3 = 114
Thus, the missing number is 4th term = 114 * 4 = 456

Hence, Option D is correct.

Let the two Trains pass after x hours,

then for Calcutta mail, we have

Distance travelled in x hours = 48x kms

Distance travelled after passing Bombay mail = 

Now, For Bombay Mail, we have

Distance travelled in x hours = 576Km

40% of 900 + x = 30% of 2600
360 + x = 780
x = 420
Hence, Option C is correct.
