MPPGCL JE Civil Mock Test - 5 - Civil Engineering (CE) MCQ

Step 1: Determine Sunny's Work Rate

• Sunny's Completion Time: 15 days to complete the work.
• Sunny's Work Rate:
  • Sunny can complete 1 work in 15 days.
  • Therefore, Sunny's work rate is 1/15 work per day.

Step 2: Calculate Bobby's Work Rate

• Bobby's Efficiency: Bobby is 60% as efficient as Sunny.
• Convert Efficiency to Fraction:
  • 60% = 60/100 = 3/5.
• Bobby's Work Rate:
  • Bobby's rate = (3/5) * (1/15) = 3/75 = 1/25 work per day.

Step 3: Determine the Number of Days Bobby Takes to Complete the Work

• Total Work: 1 work.
• Bobby's Daily Contribution: 1/25 work per day.
• Number of Days Required:
  • Days = Total Work / Bobby's Work Rate = 1 / (1/25) = 25 days.

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

Hence, Option B is correct.

Product of two numbers = HCF × LCM
1280 = 8 × LCM
160 = LCM

Checking Statement I:

Since there is no information about Monika's rank. Therefore, Rahul's rank cannot be determined.

Clearly, Statement I alone is not sufficient to answer the question.

Checking Statement II:

Aditi's rank and Monika's rank is not given. Therefore, Rahul's rank cannot be determined.

Clearly, Statement II alone is not sufficient to answer the question.

Checking Both statement I and II:

Ranks are not known for any of them. Thus, Rahul's rank cannot be found.

Clearly, Both statements I and II  is not sufficient to answer the question.

Hence, Option D is correct.

The number of students who play both the games = (30 + 50 + 40)% – 100% = 20%
Hence, Option D is correct.

Tricalcium aluminate ((C₃A)) has lost resistance to sulfate attack.

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.

(→) It has a much smaller head loss

(→) Its coefficient of discharge ((C_d=0.98)) is more

(→) Its accuracy is quite good.

We know

(W=S⋅e/G)

Where W = Water content

G = Specific gravity

e = Void ratio

For maximum water content, degree of saturation is 100%, i.e. S = 1

Then = W_a = e/G

The pattern is as follows,
1984 is the reverse of 4891
Similarly, 2874 is the reverse of 4782.
Hence the required pair is 2874 : 4782.

Water logged area means where the irrigation of water is high. For construction in this area we use the cement mortar.
Cement mortar use to hold building materials such as brick or stone together. In this water to cement ratio is higher.

The length of the straight portion of a bar beyond the end of the hook curve should be at least four times the diameter.

Hence the option C is correct.

1. Tension failure in the plates

2. Shearing failure across one or more planes and shearing failure of the rivet

3. Bring failure between the plates and the rivets.

Hence the option D is correct.

The steel is directly exposed to weather and is not accessible for cleaning and repainting. The thickness shall be not less than 8 mm. These provisions do not apply to the web of Indian standard rolled steel joists and channels to packings.

Steelwork not Directly Exposed to Weather. The thickness of steel in main members not directly exposed to weather shall be not less than 6 mm.

The thickness of steel in secondary members not directly exposed to weather shall be not less than 4-5 mm.

Hence the option B is correct.

Difference in longitude

∴38^∘45′W=38.75^∘

∴ Time difference =38.75×4=155 minutes

∵ GMT will be at east

∴ time will be 155 minutes ahead.

∴8hr12 minutes 16sec+155 minutes =10hr47 minutes 16secAM

Hence the option B is correct.

Hence the correct answer is option C

Hence the correct answer is option A.

Hence the correct answer is option B.

(D = 0.64B/∆)

Hence the correct answer is option C.

Hence the correct answer is option B.

A concrete of medium workability is represented by a compaction factor of 0.92

A concrete of high workability is represented by a compaction factor of 0.95

Basically, steel piles are a big screw, made of galvanized steel with a helical flange that not only helps to insert the pile, but also helps secure it into the ground. By using a mini-excavator with special attachments, a drill can enter the ground while measuring the load-bearing capacity of the soil.

Hence, the correct option is (D)

Velocity distribution profile equation is written as:

It is a parabolic equation, So the velocity distribution is parabolic.
