Practice Test: Civil Engineering (CE)- 13 - Question 1
Save

A monkey is trying to reach the top of a tree. He climbs 3 feet in a minute but slides down by 1.5 feet after each climb. If he reaches the top of the tree in 58 minutes, then the maximum possible height of the tree is ________ feets.

Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 1
You have to carefully observe the point that at the last minute, we DO NOT have to consider the sliding down of the monkey since the question states that the monkey reaches the top of the tree. Out of 58 minutes, the climb by the monkey in the 58th minute is 3 feet whereas for each of his earlier climbs, the monkey covers a net distance of 3 – 1.5 = 1.5 feet.

We can work out the maximum possible height of the tree as 1.5 x 57 + 3 = 85.5 + 3 = 88.5 feet

In the following question, a sentence has been given in Direct/Indirect Speech. Out of the four alternatives suggested, select the one which best expresses the same sentence in Indirect/Direct Speech.

My husband said to me, “Wait for me outside."

Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 2
This is an imperative sentence as there is instruction being given by the husband to his wife. Since the reported speech is not signifying the mode of behaviour here whether it was a request, a command or was it said in anger, we cannot use verbs related to such emotions. We'll simply convert "said to" into "told". In affirmative imperative sentences, we use "to" for connecting reporting and reported speech. The correct answer is option A as it follows the above rules correctly.

What of the following function(s) in an accurate description of the graph for the range(s) indicated?

A. y = 2x + 4 for -3 ≤ x ≤ -1

B. y = |x-1| for -1 ≤ x ≤ 2

C. y = ||x|-1| for -1 ≤ x ≤ 2

D. y = 1 for 2 ≤ x ≤ 3

Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 3
Put value and verify

(i) y = 2x+4 is true in -3 ≤ x ≤ -1

On putting x = -3, y = 2 and x = -2,y = 0 and x = -1, y = 2

(ii) y = |x-1| is also true (x = -1, y = 2), (x = 0 ,y = 1) and (x = 1, y = 0)

(iv) y = 1 in (2 ≤ x ≤ 3) always true

(i), (ii) and (iv) are true.

A rectangular room having dimensions 3.74 m x 5.78 m is required to be tiled using a minimum number of identical square tiles. The number of such tiles and area of each tile (in cm2) is given by
Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 4
In this question, we need to find the HCF of 374 and 578 which is 34. We can look at 374 = 34 x 11 and 578 = 34 x 17. This gives the number of square tiles required to cover the entire room is 11 x 17 = 187 and the area of each such tile is 342 = 1156 cm2.

In an examination, a candidate attempts all the questions since there is no negative marking and all the questions carry equal marks. Out of the first 30 questions that he attempts, he has marked correct options for 20 questions whereas out of the remaining questions, he is able to mark only one third question with correct option. His overall score in the examination is 50%.

The total number of questions in the paper are;

One-third of Ramesh’s marks in Arithmetic is equal to half his marks in English. If he gets 150 marks in the two subjects to gather, how many marks has he got in English?
Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 9

Let marks obtained by Ramesh in Arithmetic be ‘A’ and marks obtained in English be E.

As the information given,

1/3 A = E/2

à (A/3) – (E/2) = 0

à 2A – 3E= 0 ……….(i)

A + E = 150 …………(ii)

From equation (i) and (ii), E = 60

Hence, Ramesh got 60 marks in English.

In a test given by Prof Virus during the minors, Raju gets 32% marks and fails by 20 marks whereas Chatur gets 30 marks more than passing marks while scoring 42% marks. The marks required to get twice the passing marks are _______.
Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 10

The difference in percentage marks obtained by Raju and Chatur is 42 – 32 = 10% whereas the difference in their marks is 20 + 30 = 50 (Raju gets 20 marks less while Chatur gets 30 marks more than pass marks).

This gives us 1% = 5 marks and the passing marks as 20 + 32% = 180.

The required marks = 360 (twice the passing marks)

During the subsurface investigations for design of foundations, a standard penetration test was conducted at 4.5m below the ground surface. The record of number of blows is given below.

Q. Assuming the water table at ground level, soil as fine sand and correction factor for overburden as 1.0, the corrected ‘N’ value for the soil would be

Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 11
Standard penetration test – number of penetration for the first 15 cm is not counted and only the number of blows which causes further 30 cm of penetration is taken into account.

So, here N = 6 + 6 + 8 + 7 = 27

Now, here N > 15 and water table at ground level so dilatancy correction is applied.

Ncorrected = 15 + 1/2(N−15)

= 15 + 1/2(27 - 15) = 21

Deposit with flocculated structure is formed when
Detailed Solution for Practice Test: Civil Engineering (CE)- 13 - Question 15

  • The process by which individual particles of clay aggregate into coltlike masses or precipitate into small lumps. Flocculation occurs as a result of a chemical reaction between the clay particles and another substance, usually salt water.

  • In the case of flocculated structure, there will be edge to edge and edge to face contact between the particles. This type of formation is due to the net electrical forces between the adjacent particles at the time of deposition being attractive in nature.

  • The concentration of dissolved minerals in water leads to formation of flocculated structures with very high void ratio as in the case of marine deposits.
