The correct answer is Neurolema.

Key Points

• The axon, also known as a nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body.
• Also known as the neurilemma or the sheath of Schwann, neurolemma is the outermost layer of the axon.
• In the peripheral nervous system, Schwann cells create this neurolemma, which wraps around the nerve fiber, providing insulation, protection, and also aiding in the regeneration of damaged fibers.

Additional Information

• Synapse: A synapse is the junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
• Axoplasm: The axoplasm is the cytoplasm within the axon. It is contained within the axon's membrane, but it is not the outermost membrane itself. It's the 'content' inside the axon, not the 'container', which is the membrane.
• Dendrite: Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function. They are not a part of the axon's structure, so this answer is incorrect.

The logic followed here is:-

In a column: (First number × Third number) + Second number = Fourth number 

In column 1: ( 7 × 3 ) + 8 = 21 + 8 = 29

In column 2: ( 4 × 3 ) + 7 = 12 + 7 = 19

In column 3: ( 5 × a ) + 6 = 31 

5a + 6 = 31

5a = 31 - 6

5a = 25

a = 25/5

a = 5

Hence, the correct answer is Option 4: 5

Given Data:

The number to be multiplied is 392.

Concept/Formula Used:

A number is a perfect square if its prime factors all appear an even number of times.

Solution:

Prime factorize the given number 392:

⇒ 392 = 2^3 × 7^2

To get a perfect square, each number in the prime factorization should appear an even number of times. Here, the power of 2 is not even. To make it even, we need one more 2.

Therefore, the smallest positive integer that we need to multiply 392 by to get a perfect square is the missing 2.

Therefore, the smallest positive integer that when multiplied with 392 results in a perfect square is 2.

The correct answer is Isohyets.

Key Points

• The lines joining places with equal rainfall are called Isohyets.
• Isohyets are lines on a map connecting areas that receive equal amounts of rainfall or precipitation in a given period.
• They are an important tool in the fields of meteorology and hydrology, and they assist in understanding the distribution of rainfall across different geographic regions.

Additional InformationContour Lines: Contour lines are lines drawn on a map connecting points of equal elevation, and are used primarily in topographic maps to indicate valleys, mountains, and the steepness of slopes.

The correct answer is Brimstone.

Key Points

• Brimstone is an ancient name for sulphur, particularly used in biblical contexts.
• In its natural state, brimstone, or sulphur, is a bright yellow crystalline solid.
• The name 'brimstone' translates to 'burning stone' as it burns easily, producing a blue flame.
• When burned, brimstone emits a strong, unpleasant smell, similar to that of rotten eggs, caused by sulphur dioxide gas.
• Sulphur occurs in pure form near volcanoes and hot springs and also in various minerals such as gypsum and iron pyrite.
• Brimstone is used in a wide range of industries, including the production of fertilizers, chemicals, and in the vulcanization of rubber.
• Despite its many uses, sulphur (brimstone) can also be destructive, contributing to acid rain when combined with water in the atmosphere.

The correct answer is Cornwallis.

Key Points

• The Treaty of Seringapatam signed in 1792, it ended the Third Anglo-Mysore War.
• Its signatories included Lord Cornwallis on behalf of the British East India Company and Tipu Sultan, the ruler of Mysore.

Additional Information

• Consequences of the war:
• As per the treaty, Tipu had to cede half of his kingdom to the English.
• He paid Rs.3 Crore as war indemnity to the British.
• Tipu also had to surrender two of his sons as surety to the British till he paid his due.

Calculation: 

Start with the given number: ⇒ 14785

Subtract 358: ⇒ 14785 - 358 = 14427

Subtract 4158: ⇒ 14427 - 4158 = 10269

Finally, subtract 9514: ⇒ 10269 - 9514 = 755

⇒ 14785 - 358 - 4158 - 9514 equals 755.

Hence, the correct answer is "755".

The correct answer is Gautamiputra Satakarni.

Key Points

• The Satavahana dynasty ruled in central and southern India starting from around the 1^st Century BC.
• Among the Satavahana rulers, Gautamiputra Satakarni is considered the most eminent. His reign is generally dated to circa 106-130 CE.
• He is considered one of the greatest kings of the Satavahana Dynasty.
• His reign marked the high point of the dynasty’s power.
• He is known to have defeated the Western Kshatrapas and stopped their expansion.
• His reign is marked by prosperity, territorial expansion, and significant achievements in administration, maritime trade, and arts.

Additional Information

• Second Pulakeshin: Pulakeshin II was the most famous ruler of the Chalukya dynasty, not the Satavahana. He reigned in the Deccan area of India from 610 to 642 CE.

The count of triangles are as follows:

Thus there are 28 triangles in the figure.

Hence the correct answer is Option 2: 28

Given Data:

Selling price of the shirt when there is profit: Rs. 863

Selling price of the shirt when there is loss: Rs. 631

Concept/Formula Used:

In this type of problem, where the profit and loss are the same amount, the cost price of the item is the average of the two selling prices.

Solution:

Add the two selling prices: ⇒ Rs. 863 + Rs. 631 = Rs. 1494

Divide by 2 to find the average, which will present us with the cost price of the shirt:

⇒ Rs. 1494 ÷ 2 = Rs. 747

Hence, the cost price of the shirt is Rs. 747.
