The provided sequence represents the Continents of the World arranged in descending order based on their total geographical land area.

2. Asia  is the largest continent, covering approximately 44,579,000 square kilometers, which is about 30% of Earth's total land area. Hence, 2 is the first entry.

3. Africa ranks as the second-largest continent, spanning roughly 30,370,000 square kilometers and accounting for about 20% of the planet's land surface. Hence, 3 follows Asia.

1. North America is the third-largest continent with an area of about 24,709,000 square kilometers. Hence, 1 is the third entry.

4. South America occupies the fourth position, covering an area of approximately 17,840,000 square kilometers. Hence, 4 is the fourth entry.

6. Antarctica  is the fifth-largest continent, encompassing about 14,200,000 square kilometers and is nearly double the size of Australia. Hence, 6 is the fifth entry.

5. Europeis the sixth-largest continent, measuring roughly 10,180,000 square kilometers. Hence, 5 is the sixth entry.

7. Australia is the smallest continent on Earth, covering approximately 8,600,000 square kilometers. Hence, 7 is the final entry.

Now,

Correct order is: 2, 3, 1, 4, 6, 5, 7

Hence, the correct answer is “Option 4”.

1. Point (4): It is the most fundamental dimensionless unit in geometry.
2. Line (1): A one-dimensional figure formed by connecting at least two points.
3. Angle (3): Formed when two lines or rays intersect at a common vertex.
4. Triangle (2): A closed polygon formed by three lines meeting at three angles, creating a two-dimensional shape.

The logical sequence is 4 → 1 → 3 → 2.

Therefore, the correct meaningful order for the given words is 4132.

Hence, the correct answer is “Option 3”.

Mirror image of given figure is,

Hence, the correct answer is “Option 4”.

Pattern followed here is,

Similarly,

Hence, the correct answer is “Option 3”.

Logic followed here is.

Logic: The figures are categorized into groups based on their geometric shapes and the number of sides that form each boundary.

For Group (2, 3, 6) → Figures 2, 3, and 6 are all Having their smaller one inside the larger one on the lower side.

For Group (1, 7, 9) → Figures 1, 7, and 9 having their smaller one inside the larger one in the centre.

For Group (4, 5, 8) → Figures 4, 5, 8 are intersect in equal parts.

Therefore, the figures can be grouped into the classes 236, 179, 458.

Hence, the correct answer is “Option 1”.

Pattern followed here is,

Hence, the correct answer is “Option 4”.

BODMAS Table: 

Given equation: 70 − 2 ÷ 5 + 102 × 6 = ?

Now, replacing the symbols:

⇒ 70 ÷ 2 × 5 - 102 + 6 = ?

⇒ 70 ÷ 2 × 5 - 102 + 6 = ?

⇒ 35 × 5 - 102 + 6 = ?

⇒ 175 - 102 + 6 = ?

⇒ 175 - 102 + 6 = ?

⇒ 73 + 6 = ?

⇒ 79.

Hence, the correct answer is "Option 3".

BODMAS Table: 

Given equation: 6 $ 20 @ 12 # 7 % 1 = ?

Now, replacing the symbols:

⇒ 6 - 20 + 12 × 7 ÷ 1 = ?

⇒ 6 - 20 + 12 × 7 ÷ 1 = ?

⇒ 6 - 20 + 12 × 7 = ?

⇒ 6 - 20 + 84 = ?

⇒ 6 - 20 + 84 = ?

⇒ -14 + 84 = ?

⇒ 70.

Hence, the correct answer is "Option 3".

Triangles in the given figure,

21 + 21 + 21 + 21 = 84

Total Triangles = 84 + 13 = 97

Hence, the correct answer is “Option 3”.

Pattern followed here is,

Hence, the correct answer is “Option 1”.
