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 followed is:

The bottom number = sum of the square of all the first three number column-wise 

In column-wise operation:

Column 1:

69 = 7² + 4² + 2² 

69 = 49 + 16 + 4

69 = 69

Column 2:

91 = 32 + 92 + 12 

91 = 9 + 81 + 1

91 = 91

Similarly,

Column 3:

? = 22 + 62 + 52 

? = 4 + 36 + 25

? = 65 

Hence, the correct answer is "65".

Additional Information

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 patterns 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the patterns 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. 

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.

Let AB be the building and AC be its shadow.
Then, AC = 20m and ∠ACB = 60°. Let AB = x m.
Presently AB/AC = tan 60° = √3 => x/10 = √3
=> x = 10√3m = (10 * 1.732) m = 17.32m.
∴ Height of the building is 17.32m.

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
