ESE (CE) Paper I Mock Test - 1 - Civil Engineering (CE) MCQ

Given:

The compound interest on a sum for 2 years = 832 

The simple interest on same sum for 2 years = 800 

So, the difference between compound interest and simple interest = Rs 832 - 800 = 32 

Diff. in C.I. \& S.l. for 2 years = Rs 32

Simple Interest for 1 year = Rs 400.

Simple interest on Rs 100 for 1 year = Rs 32.

Hence, diff. in C.I. and S.I. for 3^rd year = S.I. on Rs. 832 = Rs
= Rs 66.56 
Total difference = Rs (32 + 66.56) = Rs 98.56 
So, The difference between the compound interest and the simple interest for 3 years will be Rs 98.56.

Appraisal cost should be minimum to get optimum level of quality of production.

Cost of Quality is the cost of those activities which an organization has incurred in order to maintain the quality over and above the minimum cost required to complete the production. It is broadly classified into two divisions:

• Cost of Conformance: The cost incurred while providing the products or services of required standards is called the cost of conformance. It includes the cost of prevention and the cost of the appraisal.
• Cost of Non-Conformance: It is also called the cost of failure and it takes place due to the products not operating as per the required specifications and standards. It includes the cost of internal failure and the cost of external failure.

Appraisal costs: Costs that are incurred to identify defective products before they are shipped to customers. These are also called 'Inspection Costs'. Ex- Final product testing and inspection cost, QC cost.

Hence the correct option is (C).

Radioactive radiation:

• Radiation is the energy or particles that are released during radioactive decay. The radioactivity of a material refers to the rate at which it emits radiation. Nuclear explosions cause radioactive radiation.
• The three most common types of radiation are alpha particles, beta particles, and gamma rays.

Tsunami:

• A tsunami is an ocean wave or series of waves caused by a sudden disturbance of the ocean floor that displaces a large amount of water.
• Tsunamis are caused generally by earthquakes, less commonly by submarine landslides, infrequently by submarine volcanic eruptions and very rarely by large meteorite impacts in the ocean.

Acid rain:

• When the quantity of acids in the raining water is more than the average, then such rain is called 'Acid rain'. It is a a major environmental issue.
• It refers to the ways in which acid from the atmosphere is deposited on the earth’s surface.
• Oxides of nitrogen and sulphur which are acidic in nature can be blown by the wind along with solid particles in the atmosphere and finally settle down either on the ground as dry deposition or in water, fog, and snow as wet deposition.

Meteorology:

• It is the scientific study of the atmosphere that focuses on weather processes and forecasting.
• Air movements influence the fate of air pollutants. So, any study of air pollution should include a study of the local weather patterns (meteorology).
• If the air is calm and pollutants cannot disperse, then the concentration of these pollutants will build up.

Material science is the branch of engineering which deals with the study of structure, properties and applications of materials. A wide variety of materials are used in applications where resistance to mechanical loading is necessary. These are collectively called engineering materials and can be broadly classified as metals and alloys, polymers, ceramics and glasses, and composites. Properties of materials are greatly influenced by the structure of materials. Material properties are dependent on their micro-structure and response to force fields and surface interaction.

A Pareto chart is a bar graph. In quality control, Pareto charts are useful to find the defects to prioritize in order to observe the greatest overall improvement. It often represents the most common sources of defects, the highest occurring type of defect, or the most frequent reasons for customer complaints. It is one of the 7 tools of Quality Management. It is a statistical technique in decision making for selection of limited tasks which have significant overall impact. It is a series of bars whose height reflects the frequency or impact of problems. The bars are arranged in descending order of heights, from left to right. An example of the pareto chart representing various type of defects in production is given below:

Hence the correct option is (B).

Given:

A can complete a piece of task in = 10 hours

B and C together can complete in = 12 hours

A and C together can complete it in = 6 hours.

Formula:

Total work = Efficiency x Time Taken

Calculation:

Total work = 60 unit (LCM of 10, 12, 6)

Efficiency of A  = 60/10 = 6 units/day

Efficiency of C  = (60/6) - 6 = 4 units/day

Efficiency of B = (60/12) - 4 = 1 units/day

∴  B alone can complete the whole work in = 60/1 = 60 hours.

In the mixture, let the quantity of milk = 3a litres and the quantity of water = a litres

In 20 litres another mixture, the quantity of milk  = (20 x 2)/5 = 8 litres

The quantity of water  = (20 x 2)/ 5 = 12 litres

The quantity of milk = 3a + 8 litres

The quantity of water = a + 12 litres

Total quantity of mixture = 4a + 20 litres

Therefore, according to the question,

⇒ 33.75% of (4a + 20) - a + 12

⇒ 1.35a - a  = 12 - 6.75 = 5.25

⇒ 0.35a = 5.25 

⇒ a = 15 

Total quantity of mixture = 4a + 20 = 80 litres

The attitude loyalty is concerned with the attitudes, emotions, and a sense of personal identity. It includes willingness to meet moral duties, with attachment, conviction, and trust with employer. The attitude loyalty is more a virtue than an obligation. This type of loyalty is all right when the organizations work for productivity or development of community.

The Taguchi method of quality control is an approach to engineering that emphasizes the roles of research and development (R&D), and product design and development in reducing the occurrence of defects and failures in manufactured goods. This method, developed by Japanese engineer and statistician Genichi Taguchi, considers design to be more important than the manufacturing process in quality control and aims to eliminate variances in production before they can occur.

Quality management tool that provides a visual connective process to help teams focus on the needs of the customers throughout the total development cycle of a product or process. It provides the means for translating customer needs into appropriate technical requirements for each stage of a product/process-development life-cycle. It helps to develop more customer-oriented, higher-quality products.

The process of managing the quality of services delivered to a customer according to his expectations is called Service Quality Management. It basically assesses how well a service has been given, so as to improve its quality in the future, identify problems and correct them to increase customer satisfaction.

Hence the correct option is (D).

Given,

X,Y be two poisson distributed independent random variables,

Now,

We know that,

The correlation coefficient is given by,

⇒ Cov (X,Y) = E(CY) - E(X)E(Y)

Where, Cov (X,Y) covariance of X and Y; σ =  standard deviation; E= expectation,

So,

E(X) = λ, Var(X) = λ,σ_x = √λ
E(Y) λ, Var(Y) = λ, σ_y = √λ
E(XY) = E(X)E(Y), since independent variables.

Now,

Z = X  + Y 

⇒ E(Z) = E(X) + E(Y) = 2λ
∵ Var(Z) = Var(X) + Var(Y) = 2λ
⇒σ_z= √2λ
Now,
Cov(X, Z) = E(XZ) – E(X)E(Z)
⇒ Cov(X, Z) = E(X² + XY) - E(X)E(Z)
⇒ Cov(X, Z) = E(X²) + E(XY) - E(X)E(Z)
⇒ Cov(X, Z) = Var(X) + [E(X)]² + E(XY) - E(X)E(Z)
⇒ Cov(X, Z) = λ + λ² +λ² -λ x 2λ
⇒ Cov(X, Z) = λ

Antivirus software, or anti-virus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware.

Cost of conformance is the price paid for prevention of poor quality (to avoid failure in product or services) and cost of non-conformance which is the of losses incurred due to failure of product or service because of poor quality. Thus, Total Quality Cost will depend on how much an organisation is spending to prevent poor quality and how much cost it is incurring because of failures due to poor quality. Mathematically,

Total Quality Cost = Cost of Conformance (COC)+Cost of non Conformance (CONC).

Hence the correct option is (B).

Volume of unit cell  = a³

In FCC unit cell,

R = √2a/4
