KVS Librarian Exam Tier 1 Mock Test - 5 Free Online Test 2026

The pattern followed here is:

83 + 4 = 87                  (i.e., 2² = 4)

87 + 9 = 96                  (i.e., 3² = 9)

96 + 16 = 112 ≠ 114    (i.e., 4² = 16)

112 + 25 = 137             (i.e., 5² = 25)

In place of 114, there should be 112.

Hence, 114 is the wrong term in the given series.

1. Filariasis
3. Film
2. Filterable
4. Filtration
Hence, answer is 1324.

The least possible Venn diagram for the given statement is as follows,

Conclusions:
I. Some pens are tables → it’s possible but not definite hence, it is false.
II. Some chairs are pens → definitely true.
Clearly, only conclusion II follows.

The pattern of series is:

Thus, instead of ‘K’ it should be ‘L’.

Given elements: Delhi, Goa, State
Here, Goa is a state and Delhi is a UT.

Hence, the answer is option 1.

Net Profit = Total Revenue – Total Expense = Rs. 43296 – Rs. 9899 = Rs. 33397

Let, the profit share of Q is Rs. x.
→ P’s profit share = Rs. 2x/3
→ R’s profit share = Rs. x/2

Thus we have,
Net Profit = P’s profit share + Q’s profit share + R’s profit share
33397 = 2x/3 + x + x/2
33397 = (4x + 6x + 3x)/6
33397 = 13x/6
x = (33397 × 6)/13
= 15414
R’s share = 15414/2 = 7707
Hence, Rs. 7707 is the correct answer.

Total sales of company Y from 2011 to 2015,
⇒ 75 + 110 + 75 + 115 + 80
⇒ 455 lacs
∴ average sales of company Y from 2011 to 2015,
⇒ 455/5
⇒ 91 lacs

Given,
Speeds of a boat along the current and against the current are 28 km/hr and 16 km/hr respectively.
Speed downstream = 28 km/hr
Speed upstream = 16 km/hr
Speed of the current = 1/2 × (speed downstream - speed upstream)
Speed of the current = 1/2 × (28 - 16) = 12/2 = 6
∴ Speed of the current is 6 km/hr.

Time taken by Rajan and Geeta to complete the work = 6 days

As we know, work is directly proportional to time, w/t = constant

Time taken by Ramesh to complete work = 15 days

According to the question,
1/15 + 1/x = 1/6

Where x = time taken by Geeta to complete the same work,
⇒ 1/x = 1/6 – 1/15
⇒ x = 10 days

For finding the efficiency of Rajan,
1/10 + 1/y = 1/9

Where, y = time taken by Rajan alone to complete the same work,
⇒ 1/y = 1/9 – 1/10
⇒ 1/y = 1/90
∴ y = work efficiency of Rajan = 90 days

For successive discount,
Successive discount = (-a) + (-b) + (-a)(-b)/100
Here, a = 30%, b = 30%
∴ Successive discount offered = (-30) + (-30) + (900/100) = -60 + 9 = -51%

⇒ (3a)² + (1/a)² = 43
As we know, (x + y)² = x² +  y² + 2xy

As we know, (x + y)³ = x³ + y³ + 3xy(x + y)

Let x litre of first mixture and y litre of the second mixture are mixed.
Quantity of milk in x litre of first mixture = 5x/6
Quantity of milk in y litre of second mixture = 3y/10
Total quantity of the resultant mixture = (x + y)
Quantity of milk in (x + y) litre of the resultant mixture = (x + y) /2
5x/6 + 3y/10 = (x + y) /2
⇒ (25x + 9y) /30 = (x + y) /2
⇒ 25x + 9y = 15 × (x + y)
⇒ 25x + 9y = 15x + 15y
⇒ 10x = 6y
⇒ x/y = 3/5
∴ required ratio = 3 : 5

Alternative method :
Concentration of spirit in the first mixture = 5/6
Concentration of spirit in the second mixture = 3/10
Concentration of spirit in the resultant mixture = 1/2
By rule of allegation,

∴ Required ratio = (1/5) : (1/3) = 3 : 5

The Hypertext Transfer Protocol (HTTP) is an application layer protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access,

The World Wide Web, commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hyperlinks, and are accessible over the Internet.

The error lies in part 2 of the sentence as the preposition 'with' cannot be used with the verb 'impart' and it must be eliminated. 'Impart' means 'convey something.' It should read as: ' They also impart him  priceless knowledge about..' 

The underlined part is incorrect here. The verb 'found' in the past tense is correct as the sentence is constructed in the simple past tense. Thus, Option 3 is the correct answer.

The error lies in part 2.
The sentence uses the noun 'nobody', which takes a singular verb. So, the verb must be 'knows' and not 'know'.
Therefore, the correct answer is option 2.

There are no grammatical errors in the given sentence. Therefore, the correct answer is option 4.

The sentence has no error in it and has been structured correctly. Option 4 is thus the correct answer.
