BSF Sub Inspector (SI) Mock Test - 5 - BSF SI/ASI MCQ

4’s multiples are:
12, 16, 20, 24, …
a = 12 and d = 4
2 is the remainder for 250 / 4.
250 – 2 = 248 which is divisible by 2.
12, 16…248
nth term, a(n) = 248
a(n) = a + (n − 1) x d
248 = 12 + (n-1) × 4
236 / 4 = n - 1
59 = n - 1
n = 60

The figure is as follows:

Assuming, the radius of circle be r.
Then,
AB = BC = CA = 2r
So, all the three sides are equal of the triangle.
△ABC is an equilateral triangle.
Hence, the required answer is equilateral triangleequilateral triangle.

x% of y% of 125 = 5% of 900

x × y = 3600
Hence, Option D is correct.

As we know that the angles are supplementary so sum of angles will be 180 degree.
Let us assume that the ratio factor is r.
According to question,
Angles are supplementary and have a ratio of 1:4.
r + 4r = 180
⇒ 5r = 180
⇒ r = 180/5
⇒ r = 36

Improvement in transport has helped in promotion of:

• Globalisation: Improved transport has facilitated the movement of goods, services, and people across borders, thereby promoting global trade and integration.


• Liberalisation: Better transportation infrastructure has supported the liberalization of markets, allowing for increased competition and the removal of trade barriers.


• Privatisation: The development of transportation systems has often been accompanied by privatization efforts, leading to increased efficiency and investment in transport services.


• None of these: None of the above options are correct. Improvement in transport has indeed played a significant role in promoting globalization, liberalization, and privatization.

Therefore, the correct answer is A: globalisation.

The word monsoon comes from the Arabic word mausim, which means weather. Owing to the yearly appearance of torrential rain, indicating a marked shift in weather, mausim gradually became monsoon.

Explanation: A globe is a three-dimensional representation of the Earth, and it does not represent the Earth on a flat surface. The other options are limitations of the globe. The distortion is seen in the regions around the poles; details are given in the form of symbols, and it is difficult to study the detailed part of the Earth on a globe due to its small size and scale.

• According to the data released by the Ministry of Commerce and Industry, the eight-core sector industries recorded a growth of 5.5% in February 2020.

• The area between the Tropic of Cancer and the Tropic of Capricorn is known as the Torrid Zone.
• The mid-day Sun is exactly overhead at least once a year on all the latitudes in this area; hence, this area receives maximum amount of heat.

The correct answer is '1577'.

Key Points

The WHO was established by constitution on 7 April 1948, which is celebrated as World Health Day.

In the higher hill ranges of northeastern India; for example, hilly areas of West Bengal and Uttaranchal, evergreen broadleaf trees such as oak and chestnut are predominant. Chir, deodar, pine, etc. are the important species of temperate forests.

Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.

Assertion: Tax on imports is an example of trade barriers.


Reason: Government can use it to increase or decrease foreign trade.
The given statement presents an assertion and a reason. Let's analyze each component separately and then evaluate their relationship.
Assertion: Tax on imports is an example of trade barriers.
- Trade barriers refer to any policy or measure implemented by the government to restrict or control the flow of goods and services across national borders.
- Tax on imports, also known as import duties or tariffs, is a common trade barrier used by governments to discourage the influx of foreign goods and protect domestic industries.
- By imposing taxes on imported goods, the government can make them more expensive compared to domestically produced goods, thereby promoting local industries and reducing foreign competition.
Reason: Government can use it to increase or decrease foreign trade.
- The government has the authority to manipulate the level of trade by adjusting the tax rates on imports.
- By increasing import taxes, the government can discourage imports and reduce foreign trade, thereby protecting domestic industries and promoting self-sufficiency.
- On the other hand, reducing import taxes can encourage imports and increase foreign trade, which may be beneficial for certain industries or to promote international relations.
Now let's evaluate the relationship between the assertion and the reason:
- The assertion states that tax on imports is an example of trade barriers, which is true.
- The reason provides a valid explanation for why tax on imports is a trade barrier, as it highlights the government's ability to influence foreign trade through the manipulation of import taxes.
Based on this analysis, we can conclude that both the assertion and the reason are true, and the reason is the correct explanation of the assertion. Therefore, option A is the correct answer.

A full circle is 360 degrees. The distance from the equator to either of the poles is one-fourth of the circumference of the Earth. Since a circle measures 360 degrees, one-fourth of that circle (representing the distance from the equator to either pole) would also measure ¼ of 360 degrees, which is 90 degrees.

Scrap value is the worth of a physical asset's individual components when the asset itself is deemed no longer usable. The individual components, known as scrap, are worth something if they can be put to other uses. Sometimes scrap materials can be used as-is and other times they must be processed before they can be reused. An item's scrap value—also called residual value, break-up value, or salvage value—is determined by the supply and demand for the materials it can be broken down into.

The purpose of lateral ties in short concrete columns is to avoid buckling of longitudinal bars.

Hence the option A is correct.

Warping stress is due to daily variation in temperature, whereas frictional stress is due to seasonal variation of temperature.

Hence the correct answer is option A.

speed V= 45 kmph

reaction time t = 0.8 sec

length of vehicles L = 5 m

space s = 0.278 Vt + L

= 0.278 x 45 x 0.8 + 5

= 10.008 + 5

= 15.008 m

theoretical capacity C = 1000V/S

= 2998.4

= 2998(say)

So theoretical capacity C = 2998 vehicles/hour/lane

Hence the correct answer is option B.

CBR is based on the strength parameters of subgrade soil.

Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm2 and a temperature of 100 to 130 degrees Celsius. Plywood is made up of three or more thin layers of wood. These layers are bonded together with an adhesive.

Drop panels are rectangular, just supported above the Capital. Capital is the enlarged shape to support the drop panel.

Sandstones are made of sand grains that have been cemented together. Like sandpaper, sandstones usually have a rough, granular texture.

Grain size - 0.06 - 2mm

Hardness - variable, soft to hard, depends on clast and cement composition.

Colour - variable through a grey, yellow, red to white reflecting the variation in mineral content and cement.

Hence, the correct option is (D)

Acc to IRC the max value of superelevation to be provided is 0.07.

The maximum superelevation for a roadway section depends on climatic conditions, type of terrain, and type of development. Roadways in rural areas are typically designed with a maximum superelevation rate of 8 percent.

Hence, the correct option is (A)

The degree of efflorescence is given as

(a) NIL – When there is no perceptible deposit of efflorescence.

(b) SLIGHT- Not more than 10% area of the brick covered with a thin deposit of salt.

(c) MODERATE- Covering up to 50% area of the brick.

(d) HEAVY- Covering 50% or more but unaccompanied by powdering or flaking the brick surface.

(e) SERIOUS- When there is a heavy deposit of salts accompanied by powdering and flaking of the exposed surfaces.

As per IS 800:2007, in a bolted joint to ensure that the effect of bending stress is less than the specified value in the code, the grip length, L_g [/ngtr?] 5d

where d = diameter of the bolt

To take care of additional bending stress developed in the connection,

5d < L_g <  8d

If  L_g > 8d then the section should be redesigned.
