Gate Mock Test Civil Engineering (CE)- 4 - Question 7

Three pipes A, B and C are attached to a tank. A and B can fill it in 20 and 30 minutes, respectively, while C can empty it in 15 minutes. If A, B and C are kept open successively for 1 minute each, how soon will the tank be filled if pipe A is opened first?

Detailed Solution for Gate Mock Test Civil Engineering (CE)- 4 - Question 7
The part of tank filled by Pipe A in 1 minute = 1/20

The part of tank filled by Pipe B in 1 minute = 1/30

The part of tank emptied by Pipe C in 1 minute = 1/15

So, totally in 3 minute (because open for 1 minute each) = 1/20 + 1/30 - 1/15 = 1/60

Consider 55/60 can be filled in 3 × 55 = 165 minute, remaining part is 1/12.

A can fill 1/20 in 1 minute.

So, capacity left is, (1/12) - (1/20) = 1/30

B can fill the remaining 1/30 in 1 minute.

So, total time taken = ((3 × 55) + 1 + 1) = 167 minute

it will take 167 minutes to fill the tank.

Gate Mock Test Civil Engineering (CE)- 4 - Question 8

Directions: Figure (A) below shows an unfolded cubical dice. This unfolded figure is followed by four different figures of dice. You have to select the figure which is identical to figure (A).

Detailed Solution for Gate Mock Test Civil Engineering (CE)- 4 - Question 8
As per figure (A), we get that @ is opposite to *, % is opposite to # and $ is opposite to =. The characters which are in the adjacent faces cannot be opposite to each other.

From this, it is clear that only figure (c) is possible.

So, option (3) is the correct answer.

Gate Mock Test Civil Engineering (CE)- 4 - Question 9

Gate Mock Test Civil Engineering (CE)- 4 - Question 10

Directions: This problem consists of a question followed by two statements numbered I and II given below it. Read the statements carefully and decide which of them is/are sufficient/necessary to answer the question.

S is to the north of P and T is to the east of S. What is the exact distance between P and T?

I. Distance between S and T is double the distance between S and P.

II. Distance between S and T is 4 cm.

Detailed Solution for Gate Mock Test Civil Engineering (CE)- 4 - Question 10
From I alone, we can use Pythagoras theorem to find the answer, however, as no distance is mentioned, therefore I alone isn't sufficient.

From II alone, we can't figure out the distance between P and T as distance between S and P isn't given.

From I and II together, we can easily find the required distance.

Distance = cm

Gate Mock Test Civil Engineering (CE)- 4 - Question 12

Instruction: [This is a multiple-select question, one or more than one option can be correct]

After conducting a slump cone test on the work site for two different batches of concrete 'X' and 'Y', the following results were obtained:

1) 'X' batch shows zero slump

2) 'Y' batch shows collapsed slump

For the above results, the correct option is/are

Detailed Solution for Gate Mock Test Civil Engineering (CE)- 4 - Question 12
Options (B), (C), and (D) are correct. As 'X' batch shows zero slump that means there was no significant fall in the concrete and it stays in the position of the mould which is the indication of a very low water-cement ratio, which results in dry mixes. This type of concrete is generally used for road construction. Y' batch shows collapsed slump means the concrete breaks and spreads in all directions and is an indication that the water-cement ratio is too high, i.e. concrete mix is too wet or it is a very highly workable mix. 'X' and 'Y' both are not suitable from a quality and durability perspective because 'X' will result in poor compaction and honeycombing issues later and 'Y' will result in a very low-strength concrete which is highly prone to segregation and bleeding.

Gate Mock Test Civil Engineering (CE)- 4 - Question 28

The degree of static indeterminacy of the following beam is :

Detailed Solution for Gate Mock Test Civil Engineering (CE)- 4 - Question 28
The number of support reactions = 2 (A is pin support) + 1 (C is a roller support) + 3 (D is a fixed support)

r = 2 + 1 + 3 = 6 ⟹ r = 2 + 1 + 3 = 6

Number of equilibrium equations = 3 (global equilibrium) + 1 (due to internal hinge)

e = 3 + 1 = 4 ⟹ e = 3 + 1 = 4

Degree of static indeterminacy, SI = r − e = 6 − 4 = 2SI = r − e = 6 − 4 = 2

Note: The number of additional equilibrium equations obtained due to presence of hinge = n - 1 (where n = number of members connected to the hinge). Here, n = 2; hence number of additional equilibrium equations = (2 - 1) = 1
