Jammu & Kashmir SI Mock Test - 1 - Jammu & Kashmir SI MCQ

L - 2 = J, J + 7 = Q
P - 2 = N, N + 7 = U
U - 2 = S, S + 7 = Z
R - 2 = P, P + 7 = W
So, RPU is the odd one out.

(20 ÷ 5) - (24 + 6) x 9 = ?
After interchange of signs:
(20 + 5) x (24 ÷ 6) - 9 = ?
⇒ 25 x 4 - 9 = ?
⇒ 100 - 9 = ?
⇒ ? = 91
So, option (c) is the correct answer.

256 = (16)² : 16 + 1 =17
529 = (23)² : 23+1=24
1156 = (34)² : 34+1=35

So, option (c) is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.

LCM of the numbers = 840
HCF of the numbers = 840/(3*7*5) = 8
Sum of smaller and larger number = 8*(3 + 7) = 80

(a + b)³ = a³ + b³ + 3ab (a + b)
(X + 6Y)³ = X³ + 216Y³ + 3 * X * 6Y (X + 6Y)
9³ = X³ + 216Y³ + 3 * 3 * 6 (9)
729 = X³ + 216Y³ + 486
X³ + 216Y³ = 729 - 486 = 243

Average = (sum of observations)/(number of observations)
Then, sum of weights of all students + sum of weights of two teachers = sum of weights of students and two teachers
32 * 40 + 2 * average weight of two teachers = (32 + 2) * (40 + 1.5)
Average weight of two teachers = ( 1411 - 1280)/2 = 65.5 kg

Simple interest = sum * rate * time/100
2080 = 6500 * 2t * t/100
t² = 16
t = 4

Given that
Rajas had 258 Rupees
He bought 3 pens with each pen's cost being 6 rupees
Therefore, cost of 3 pens = 3 X 6
Cost of 3 pens =18
Cost of pencil = 2/3*6= 4
Cost of 8 pencils = 8 X 4 = 32
Amount of money left with Raja=258-18-32= Rs. 208

4√x = √35 + 3√35 = 4√35
⇒ x=35

Let the speed of the man and current be x km/hr and y km/hr respectively.
(3/4)/(15/60) = x - y
x - y = 3 ........ (i)
(3/4)/(10/60) = x + y
x + y = 9/2 ........ (ii)
On solving,
x = 15/4 km/h
y = 3/4 km/h
Required ratio = 15/4 : 3/4 = 5: 1

The subject of the Active Voice is changed into the object of the Passive voice. Also, the object of the Active Voice is changed into the subject of the Passive Voice.

The usage of a "to be" form of the verb ['be' here] is necessary while changing the voice of the sentence from Active to Passive.

In Passive Voice, the preposition "by" is used before the object. However, it is optional in some cases.

These types of questions contain Modal verbs. Some of the modal verbs are: Can, could, may, might, shall, should, will, would, must, and ought to.

The format of such a sentence in Active Voice is: Subject + Modal + V1 + Object.

Thus, in Passive voice, the format will be: Object of the active voice (Subjective case) + Modal + be + V3 + by + Subject of the active voice (Objective case).

For example:
You can do this. (Active Voice)
This can be done by you. (Passive Voice)
The options except (a) don't follow the correct grammatical format of the Passive Voice.
Hence, the correct answer is option (a).

Note:
V1 -> Base form/simple form of verb, V2 -> Past form of verb (-ed form or irregular verb), V3 -> Past participle form of verb (-ed, -d, -t, -en, or -n), V4 -> Continuous form of verb / Present participle form of verb (-ing form), V5 -> Third person singular (V1+ -es or -s).

A Preposition is a word placed before a noun or a pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition) and shows a relationship in space or time or a logical relationship between two or more people, places, or things in a sentence.

Examples
I. The teacher scolded the child for being late.
II. We're going to a party.

• The words in bold are called prepositions because they normally take position before (pre) a noun/pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition.
• The noun/pronoun which is used with a preposition is called its Object.

Among the given options, 'hear' fits in the blank appropriately because it correctly conveys the idea that the speaker is capable of perceiving the soothing sound of raindrops falling on the roof with their ears.
The complete sentence is: I can hear the soothing sound of raindrops falling on the roof.
Hence, (c) is the correct answer.
Hare - This is a noun referring to a type of animal, so it doesn't fit the context of the sentence.
Hair - This is also a noun, referring to the strands that grow on our heads or bodies.
Here - "Here" is an adverb indicating a location or presence, and it doesn't fit the context of perceiving a sound. All these options do not fit in the blank contextually.

According to grammar rule- If stress, emphasis, investigate, consider, accompany, pervade, discuss, tell, order, reach, attack, demand, control, resemble, ensure, join, etc., are used in active voice then no preposition should be used. So, no preposition should be used here. 'To' is used for approaching or reaching a particular condition. 'About' is used for showing concern/approximation. 'From' is used to expressing the point in time at which a particular process, event, or activity starts.

Hence, option (d) is the correct choice.

Determiners are words that make the reference of nouns more specific. 'A' specifies the quantity as 'one' but 'metal cans' is a plural noun. 'A little' and 'much' are used before uncountable nouns but 'metal cans' is a countable noun. 'The' is used before nouns that are specific in nature and here the cans are specifically metallic so it is the right choice.

Hence, option (b) is correct.

Mean = sum of observations/number of observations
Here, number of observations = 10
Mode = most frequently occurred term = 13
Case 1: When m = 13
Then, 11 = (6 + 13 + 2n + 1 + 19 + 11 + 5 + 13 + 13 + 9 + 11)/10
n = 4.5 (not possible)
Case 2: When 2n + 1 = 13 => n = 6
Then, 11 = (6 + 13 + 13 + 19 + 11 + 5 + 13 + m + 9 + 11)/10
m = 10
So, m + n = 10 + 6 = 16

Sides of the cubes are 'n' cm and 20 cm.
Length, breadth and height of cuboid are 35 cm, 25 cm and 13 cm respectively.
Area of cubes = area of cuboid
n³ + 20³ = 35*25*13
n³ + 8000 = 11375
n³ = 3375
n = 15

Let sides are 10x cm, 24x cm, and 26x cm, respectively.
Area = 480 cm²
⇒ 1/2 * 10x * 24x = 480
⇒ x² = 480 * 2/(240) = 4
⇒ x = 2

So, perimeter of the triangle = 2(10 + 24 + 26) = 120 cm

tan θ + 1/tan θ = 2
⇒ tan²θ - 2tanθ + 1 = 0
⇒ (tanθ-1)² = 0
⇒ tanθ=1
⇒ θ = π/4
Therefore cosθ = cosπ/4 = 1/√2

Microsoft PowerPoint is a presentation software that enables users to create engaging presentations that consist of individual pages, or slides, which may contain text, graphics, sound, movies, hyperlinks, and other objects.

Ransomware: 

It is a type of malware that targets user data. It either blocks the user from accessing their own data or threatens to publish the personal data online and demands ransom payment against the same.

• Some ransomware simply block the access to the data while others encrypt data making it very difficult to access.
• In May 2017, a ransomware WannaCry infected almost 200,000 computers across 150 countries.
• It worked by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It literally made its victims "cry" and hence the name.
