DSSSB AE Civil Tier 1 Mock Test - 1 - Civil Engineering (CE) MCQ

Option 2 is correct.

• Carbon monoxide (CO) is one of the most serious air pollutants, highly poisonous to living beings because of its ability to block the delivery of oxygen to the organs and tissues.
• It binds to haemoglobin to form carboxyhemoglobin, which is about 300 times more stable than the oxygen-haemoglobin complex.
• In blood, when the concentration of carboxyhemoglobin reaches about 3–4 per cent, the oxygen-carrying capacity of blood is greatly reduced.
• This oxygen deficiency results in headache, weak eyesight, nervousness and cardiovascular disorder.

• Statement-I is correct: The migration of Jains to South India during the great famine in Magadh played a crucial role in spreading Jainism in the region.
• Statement-II is correct: This migration and subsequent developments contributed to the establishment and prominence of the Digambara sect in South India. However, the Digambara sect's establishment was more directly related to doctrinal differences and practices, such as the practice of nudity, which became a point of contention.
• While Statement-II is related to the effects of the migration, it is not the direct explanation for the spread of Jainism as mentioned in Statement-I but rather a consequence of the split that occurred within Jainism following the migration and the return of some Jains to Magadh.

Statement 1 is incorrect because the Montagu-Chelmsford Reforms introduced dyarchy in provinces, which meant control was divided between elected Indian ministers and appointed British officials, not completely transferred to Indian hands. Statements 2 and 3 are correct as the Rowlatt Act did allow detention without trial to curb seditious activities, and the Jallianwala Bagh Massacre was indeed a direct result of the protests against the arrest of nationalist leaders Saifuddin Kitchlew and Dr. Satyapal.

The Matsya6000 is a manned submersible that is being developed by India's National Institute of Ocean Technology (NIOT). It is designed to reach a depth of 6,000 meters, which will make it one of the deepest-diving submersibles in the world. The Matsya6000 will be used to explore the deep ocean and study its resources, including minerals, marine life, and ecosystems.

To solve this problem, we need to evaluate the expression (100 - 99⁰) x 100. Let's break it down step by step:
Step 1: Evaluate 99⁰: Any number raised to the power of 0 is equal to 1. So, 99⁰ = 1.
Step 2: Substitute the value of 99⁰ into the expression: (100 - 1) x 100 = 99 x 100.
Step 3: Multiply 99 and 100: 99 x 100 = 9900.
Therefore, the value of the expression (100 - 99⁰) x 100 is 9900.
Hence, the correct answer is C: 9900.

We know that: 
LCM is the least common multiple of the given numbers whereas HCF is the highest common factor of those numbers.
Then, LCM is the multiplication of one common factor of the numbers and the other different factors of the numbers.
Write the LCM = 120 into factored form, that is
120 = 2 × 2 × 2 × 3 × 5
= 4(2 × 3 × 5)
⇒ 4 is the common factor of the numbers.
So, the HCF of three numbers is a multiple of 4.
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
Therefore, 35 is not the multiple of 4, then 35 cannot be their HCF.

Logic: The alphabet that comes first alphabetically, comes first in the dictionary.

So, the correct arrangement should be:

2. Subtle.

4. Sucres.

3. Sudoku.

1. Sugary.

5. Sullen.

Hence, the correct answer is "2, 4, 3, 1, 5".

Given:

Mohit got 30% marks and failed by 25 marks

Another student scored 38% and

He got 15 more marks than passing marks

Calculation:

According to the question

⇒ 30% + 25 = 38% – 15

⇒ (38% – 30%) = (15 + 25)

⇒ 8% = 40

⇒ 1% = 5 marks

Now,

5% = 25 marks 

Then,

The necessary pass percentage required = (30% + 5%)

⇒ 35%

∴ Required pass percentage is 35%

The most suitable idiom to replace the bold part of the sentence is "fell foul of."
The phrase "fell foul of" means to get into trouble or conflict with rules, laws, or expectations, which fits the context of Meghan breaking Wimbledon etiquette.

So, the sentence would be-Meghan isn't a stranger to breaking the rules after she recently fell foul of Wimbledon etiquette.

Hence the correct answer is option A.

As per IS 456 : : 2000, clause 25.1.1

Column or strut is a compression member, the effective length of which exceeds three times the least lateral dimension.

Quadrantal circle bearing = N 25^∘W

Whole circle bearing =360^∘−25^∘=335^∘

Hence, the correct option is (c).

For a column fixed at both ends, the effective length Leff=0.5LL_{eff} = 0.5LLeff​=0.5L, where LLL is the actual length of the column.

So, the effective slenderness ratio is:

Therefore, the correct answer is:

Option C: 0.5L/r

Where C = Dickens coefficient

A = Area of the basin in sq. km.

Hence the correct answer is option D.

• Crippling stress depends only upon the geometry and Young's Modulus of a column

• Crippling stress varies parabolically with its slenderness ratio

• Crippling stress varies parabolically hardening slenderness ratio

Calculation of Carpet Area:

• Length of the building = 17.3m


• Breadth of the building = 10.3m


• Thickness of walls = 0.3m (applicable to all sides)

 

Calculating the Inner Dimensions:

• Length of inner rectangle = Length of building - 2 * Thickness = 17.3m - 2 * 0.3m = 16.7m


• Breadth of inner rectangle = Breadth of building - 2 * Thickness = 10.3m - 2 * 0.3m = 9.7m

 

Calculating Carpet Area:

• Carpet Area = Length * Breadth = 16.7m * 9.7m = 162.19m²

Therefore, the carpet area of the building is 162.19 square meters, which is closest to option D: 170m².

(D_se = 6 - 3 = 3)
