BSF Sub Inspector (SI) Mock Test - 7 - BSF SI/ASI MCQ

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
We have,
First number × second number = LCM × HCF

Given:

Efficiency of Amit = 2 × Efficiency of Ramit

Concept used:

Total work = Efficiency × Time period

Calculation:

The efficiency of Amit = 2

Efficiency of Ramit = 1

Total work = (2 + 1) × 28 = 3 × 28 = 84

Number of days Ramit takes to complete the whole work = 84/1 = 84

∴ The number of days in Ramit will complete the work is 84 days.

The logic followed is:
Top number = (sum of the bottom number)²
In fig 1:
225 = (8 + 7)²
225 = 15²
225 = 225
In fig 2:
49 = (3 + 4)²
49 = 7²
49 = 49
Similarly,
121 = (6 + ?)²
√121 = 6 + ?
11 = 6 + ?
? = 11 - 6
? = 5 
Hence, the correct answer is "5".

Hence, Option A is correct.

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see Z is good in English, Mathematics, and Science but poor in Social Studies.

Hence, the correct answer is "Z".

Let AB be the observation tower and h be its height.

Also, let the ship be at C when the angle of elevation is 30° and at D when the angle of elevation is 45°.

The time taken by the ship to travel from C to D is 10 minutes and we need to find out the time the ship will take to reach B from D.

∴ tan 30º = AB/CB = h / CB = 1/ √3

⇒ CB = √3 x h

∴ tan 45º = AB / DB = h / DB = 1

⇒ DB = h

⇒ CD = CB – DB = (√3h – h) = h(√3– 1)

Now, as h(√3 – 1) distance is covered in 10 minutes, a distance of h is covered in = 13.66 minutes = 13 minutes 40 seconds

Hence, Option C is correct.

Logic: Synonymous Relationship.

Here,
Dawn : Sunrise → Dawn and Sunrise are synonymous because they both refer to the early morning time when the sun begins to rise.

Similarly,
Easy : Simple → Easy and Simple are synonymous because they both refer to something that is not difficult.

India's Wholesale Price Index (WPI) recorded a three-month low of minus 0.52% in October, marking the seventh consecutive month of deflation and indicating a downward trend in WPI-based inflation.

Investment refers to the act of spending money with the expectation of generating future income or returns. In the context of the given options, investment can be made in various forms, such as factory building, machines, and equipment. Let's break down each option to understand how they contribute to investment:
1. Factory Building: Investing in factory buildings involves constructing or acquiring physical structures where production activities take place. This includes purchasing land, materials, and labor to establish a manufacturing facility.
2. Machines: Investment in machines refers to purchasing or leasing equipment that aids in the production process. Machines can range from simple tools to complex industrial machinery, depending on the nature of the business.
3. Equipment: Equipment investment involves acquiring necessary tools, devices, or instruments to support the production or operation of a business. This can include items such as computers, vehicles, furniture, or specialized machinery.
4. All the above: The answer option "D: all the above" indicates that investment encompasses spending on factory building, machines, and equipment. This means that investment is not limited to any single form but includes all these options.
In summary, investment involves spending on factory building, machines, and equipment. These investments are made with the expectation of generating future income or returns.

The Varuna naval exercise is a biennial exercise between the Indian Navy and the French Navy. The 21st edition of the exercise, Varuna-23, was held in the Arabian Sea in September 2023. Phase II of the exercise was held from September 6 to 9, 2023.

The Haryana Assembly passed a bill aimed at curbing illegal immigration, addressing concerns regarding the activities of unregistered travel agents. This legislative action reflects the state's efforts to tackle issues related to immigration and safeguard the interests of its residents.

i_c = (G + 1) ÷ (1 + e)
= i_c = (2.65 - 1) ÷ (1 + 0.65) = 1

Average permeability parallel to the plane of stratification depends mainly on the permeability of the most permeable layer and its value is close to the permeability of that layer.

(c) In 2D incompressible and steady flow, pressure gradient in direction of flow is zero:

Shrinkage can be reduced by using the maximum practical amount of aggregate in the mixture. The lowest water-to-cement ratio is important to avoid this type of shrinkage.

Hence the option D is correct.

The fluid whose pressure is being measured should have a mass density less than that of the manometric fluid, and the two fluids should not be able to mix readily – that is, they must be immiscible.

Hence the correct answer is option A.

Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water treatment. Ozone can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation, or final disinfection. Usually, it is recommended to use ozone for pre-oxidation before a sand filter or an active carbon filter (GAC). After ozonization, these filters can remove the remaining organic matter (important for final disinfection).

Hence the correct answer is option D.

Thus, the road stones used in the construction should be sound enough to withstand the weathering action. The property of aggregates to withstand the adverse actions of weather may be called soundness.

A retaining wall when moves away from the backfill, there is a stretching of the soil mass, and the active state of earth pressure exits

Generally, beams are placed in a transverse direction to the slab. In the direction parallel to the shorter span of the slab. Hence loading in the beam is transverse loading.

Bitumen emulsion is a liquid product in which bitumen is suspended in a finely divided condition in an aqueous medium and stabilized by suitable material.

The 'fix' of a plane table from three known points is good if the middle station is nearest.

Hence, the correct option is (A).

• Brickwork in foundation, plinth, arches, and superstructure are measured in cubic meters.

• While Brickwork for thin partition walls is measured in a square meter.

• Brick walls are measured in square meters if the thickness of the wall is half brick or as a partition wall.
