SSC CHSL Previous Paper 44 (Held On: 23 March 2018 Shift 1) (Previous Year Paper)

The correct option is Flounder. 

Key Points

Reading the given sentence we find that: 

• The word flounder is correctly spelt in the given question.
• Flounder: To struggle to move or to obtain footing; thrash about wildly.
• Example: The poor horse was floundering in the mudb.

Therefore, the correct answer is flounder.

The correct answer is ACB.

Key Points

Reading the above question we find that: 

• The first fixed part ends with an adjective small.
• Therefore it should be followed by a noun.
• Out of all the given options, only A starts with a noun.
• In option 1 ABC we find that it ends with C which has a possessive pronoun 'my' in the end.
• Since a sentence cannot end with a possessive pronoun option 1 ABC can be eliminated.
• This leaves us with the final option starting with A i.e ACB.
• Therefore the correct answer is ACB.

The correct sentence will be: **I say a small prayer whenever I ring the doorbell to my next assignment.

The correct answer is Cleaned. 

Key Points

Reading the given sentence we find that: 

• The verb kept is used in the first part of the sentence.
• Therefore the sentence is in the simple past tense.
• Thus the tense of the other verbs must align with the tense of the sentence.
• For the verb clean, its simple past tense is cleaned.

Therefore the correct answer is Cleaned. 

The correct sentence will be: We kept aside our clothes, cleaned our hiking boots and made sure we had our thick woollen socks.

The correct answer is Were replaced. 

Key Points

Reading the sentence we find that: 

• The verb "replaced" shows the sentence is in the simple past tense.
• So, past tense should be used further as well. Therefore, option 4 is wrong.
• Also, there are two subjects- the steam engines and the old first-class coaches.
• That means, plural subject, so according to the sub-verb agreement, the plural verb should be used. Thus, option 1 is incorrect.
• The given sentence is in the passive voice form in the simple past tense.
• Thus, the helping verb "were" is used with V3, i.e. replaced. So, option 2 i.e. "were replaced" is the correct answer.

Therefore the correct answer is Were replaced.

The correct answer is Reminiscence

Key Points

Let's look at the meaning of the options given below:

• Antithetic -perfect for describing something that clashes with or cancels something else out.
• Disparate - essentially different in kind; not able to be compared; unlike; unalike.
• Conjecture - an opinion or conclusion formed on the basis of incomplete information.
• Reminiscence -a characteristic of one thing that is suggestive of another; a story told about a past event remembered by the narrator.

Clearly, option 4 i.e. Reminiscence gives the best substitute for given sentence.

The correct answer is Churlish. 

Key Points

Let's look at the meaning of the given options.  

• Affable -friendly, good-natured, or easy to talk to; cordial.
• Churlish - rude in a mean-spirited and surly way.
• Cordial - friendly, good and easy to talk to.
• Genteel - characterized by exaggerated or affected politeness, refinement, or respectability.

Thus from the the given meanings we can conclude that the correct answer is Churlish.

The correct answer is A person or thing that one is extremely pleased or relieved to see. 

Key Points

Let's look at the meaning of the given sentence. 

• A sight for sore eyes: A person or a thing that one is relieved to see.
• Example: The enigmatic professor's entry was a sight for the sore eyes.

Therefore the correct answer is A person or thing that one is extremely pleased or relieved to see.

The correct answer is A device not working properly or at all. 

Key Points

Let's look at the meaning of the given phrase: 

• Be out of order: Not working properly; not in the correct sequence.

Therefore from the given meaning, we find that the correct answer is A device not working properly or at all.

The correct answer is In.

Key Points

Reading the passage we find that: 

• The passage explains on morals of not taking harsh steps to end corruption.
• It also explains that money should not be given much priority.
• Now, the blank is followed by "order".
• So, the apt word should be in, that is in order.
• It means in the correct condition for operation or use.
• So, the context explains we cannot create harsh laws to end the operation of corruption.

Thus, the correct answer is In.

The correct answer is Natural. 

Key Points

Reading the given sentence we find that:

Here we need an adjective that can give more meaning to the noun society.

Let's look at the meaning of the given options. 

• Nature: Is a noun that means the phenomena of the physical world.
• Natural: An adjective that means existing in or derived from nature.
• Naturally: An adverb that means without special intervention.
• Naturism: Is a noun that means the style and theory of representation.

Important Points

Thus from the given meanings, we find that:

• Only the word natural is an adjective and only it can be used with the noun society.
• Furthermore, the meaning of the word fits in contextually with the given sentence.

Therefore the correct answer is Natural.

The correct answer is Clear. 

Key Points

Reading the given sentence we find that:

• An adjective should be used in the blank to give more meaning to the noun definition.
• Out of all the given options, only clear is an adjective.

Therefore the correct answer is Clear. 

Additional Information

• Clearly is an adverb.
• Clarity is a noun that means to be coherent.
• Clarification: is a noun that is the art of making a statement or less confusing and more comprehensible.

The correct answer is Then.

Key Points

Reading the given sentence we find that:

• An adverb that means 'after that or next' should come here.
• Here we are talking about something that is coming after something.
• Therefore the correct adverb to be used here is Then.
• Then: An adverb which means after that; next; afterwards.

 Thus the correct answer is Then.

The correct answer is Satisfying. 

Key Points

Reading the given sentence we find that:

• The word deeply is an adverb and an adverb always modifies a verb or an adjective.
• In the given options we have a verb i.e Satisfy and an adjective i.e Satisfying.
• Reading the whole sentence we find that:
• There is no particular action is taking place in the given sentence.
• Instead, the sentence is talking about the qualities that money should have.
• Thus we need an adjective here instead of a verb.

Therefore the correct answer is Satisfying which is an adjective.

The correct answer is Possession. 

Key Points

Reading the given question we find that:

• Here, the word "possession" is correctly spelt.
• Possession: the state of having, owning, or controlling something.
• Example: She had taken possession of the house.

​Therefore, the correct answer is Possession.

Correct option - 3

Here, direct speech is given. So, we change it into indirect speech. The sentence in inverted commas is given in simple past tense. So, it changes into past perfect tense in indirect. Thus, option 3 is the correct answer.

Correct option - 2

Here, active voice is given. So, we change it into passive voice. The tense used is simple past tense. So, following pattern is used :-

Obj + was/were + V3 +by +Sub.

Thus, option 2 is the correct answer.

The correct answer is RQP.

Key Points

Reading the given question we find that:

• Clearly, the sentence does not end with a helping verb "do not" and a determiner "some", they give incomplete meaning.
• Keeping this in mind we can eliminate PRQ and PQR i.e option 1 and 2.
• QRP  i.e option 1 is incorrect because Q should be followed by the main verb, and not a noun.
• In the given question the word sensation is a noun.

Therefore the correct sequence will be RQP. 

The correct sentence is: All animals have sensation but some animals do not have memory.

The correct answer is Relaxed. 

Key Points

Let's look at the meaning of the given word and the correct option. 

• Drawn: Looking strained from illness, exhaustion, anxiety or pain.
• Relaxed: Free from tension and anxiety.

Thus from the given meanings, we find that the correct answer is Relaxed.

The correct answer is Execration. 

Key Points

Let's look at the meaning of the given option and the correct word. 

• Benison: A blessing**.**
• Execration: The act of cursing or denouncing someone.

Thus from the given meanings, it is clear that both the words express the opposite meaning. 

Therefore the correct answer is Execration. 

Additional Information

Let's look at the meaning of the other given options. 

• Amen: An utterance at the end of a prayer or hymn.
• Approval: The act of approving something.
• Blessing: A gift from the heavens.

The correct answer is Regretful. 

Key Points

Let's look at the meaning of the given word and the correct option. 

• Contrite: feeling or expressing remorse at the recognition that one has done wrong; regretful; penitent**.**
• Regretful: feeling or showing regret.

Thus from the given meanings, we find that both words express similar meanings.  

Therefore the correct answer is Regretful. 

Additional Information

Let's look at the meaning of the other given options. 

• Determined: Having reached a decision.
• Specific: Cleverly defined or identified.
• Devise: Plan or invent by careful thought.

The correct answer is Commonplace. 

Key Points

Let's look at the meaning of the given word and the correct option. 

• Banal: Common; predictable; conventional.
• Commonplace: Something that is conventional and common.

Thus from the given meanings, we find that both the words express similar meanings. 

Therefore the correct answer is Commonplace. 

Additional Information

Let's look at the meaning of the other given words. 

• Original: Present or existing from the beginning.
• Distinctive: Characteristic of one person or thing.
• Sharp: Having an edge or point that is able to cut.

Correct option - 1

Here, a positive word should be used because "not" is already given. Thus, option 2 is incorrect. And, "anyone" is used for a question or to produce a negative meaning. But, the phrase is complete till the blank, after that another phrase starts. So, option 3 is eliminated. And, 'every' is determiner that is used to point out noun but now relative pronoun "who". So, option 4 is wrong. Thus, option 1 is the correct answer.

The correct answer is All. 

Key Points

Reading the above sentence we find that: 

• All is well is a general expression in the English Language which means everything is fine.
• Thus from the given expression, we can come to the conclusion that the correct answer here should be All.
• Using all gives proper contextual meaning to the sentence that everything is not fine with her.

​Thus, the correct answer is All.

The correct answer is 2.

Key Points

Reading the given sentence we find that: 

• The error lies in the second part of the sentence.
• 'Award at its bold efforts' is wrong as the preposition for is used with Awards.
• Awards are given for an achievement.
• Thus, the preposition for should be used here in place of at.
• Example:-
• We use for to talk about a purpose or a reason for something.
• I'm going for some breakfast.
• She was waiting at the corner.

Thus we can conclude that the error lies in part 2 of the sentence.

Correct option - 2

Here, action is done by the subject "I", not the "task". It is an action that has to be done. So, it is 'I' who goes to shopping. So, replace has with is. Thus, option 2 is the correct answer.

An Army of Soldiers is a collective noun.

Similarly, a Troupe of Artist is also a collective noun.

Hence, answer is ‘Troupe : Artist’.

The pattern/logic/rule followed here is:

354 - 3 = 351

Similarly,

478 - 3 = 475

Hence, answer is ‘475’.

The pattern/logic/rule followed here is:

P - 12 = D

T - 12 = H

Similarly,

S - 12 = G

Q - 12 = E

Z - 12 = N

Hence, answer is ‘GEN’.

The pattern followed here is (Game - type of game INDOOR/OUTDOOR)

‘Indoor - Chess’ does not follows the above pattern.

Hence, ‘Indoor - Chess’ is the odd one out.

Here the pattern of relation followed is (Number - Number + 7)

All except ‘23 - 28’ follows the above pattern of relation.

Hence, ‘23 -28’ is the odd one out

The pattern/logic/rule followed here is:

1) IQY → I + 8 = Q; Q + 8 = Y

2) CKT → C + 8 = K; K + 9 = T

3) EMU → E + 8 = M; M + 8 = U

4) HPX → H + 8 = P; P + 8 = X

Clearly, ‘CKT’ does not follows the same pattern/logic/rule as other three options.

Hence, ‘CKT’ is the odd one out.

Dictionary sequence is as follows:

5. Indirect
6. Induce
7. Indulge
8. Infect
9. Inferior

Hence, answer is ‘54312’.

The logic/rule followed here is:

23 + 5 = 28; 28 + 6 = 34; 34 + 7 = 41; 41 + 8 = 49; 49 + 9 = 58

Hence, answer is ‘58’.

The logic/rule followed here is:

A + 2 = C; C + 2 = E; E + 2 = G; G + 2 = I

F + 2 = H; H + 2 = J; J + 2 = L; L + 2 = N

M + 2 = O; O + 2 = Q; Q + 2 = S; S + 2 = U

G + 2 = I; I + 2 = K; K + 2 = M; M + 2 = O

1. Rahul is taller than Richa but not shorter than Mita.

Rahul > Richa and

Rahul > Mita

2. Mita and Mukesh are of same height.

Mita = Mukesh

3. Rahul is shorter than Raju.

Raju > Rahul

From 1, 2 and 3 - we get:

CASE 1: Raju > Rahul > Richa > Mita = Mukesh 

CASE 2: Raju > Rahul > Mita = Mukesh > Richa

In both the case Rahul is the second tallest person. 

Hence, Rahul is the second tallest person.

We have to checked each Option:

Option (1): Been (Can be formed using the letters of "Benevolent").

Option (2): Nevin (Cannot be formed using ‘Benevolent’ because there is no ‘I’ in it.)

Option (3): Lent (Can be formed using the letters of "Benevolent")

Option (4): Ben (Can be formed using the letters of "Benevolent")

Hence, the correct answer is "Nevin".

The logic/rule followed here is:

The alphabet is replaced by the alphabet which have same positional value in reverse alphabetical series.

F → U

P → K

S → H

Hence, answer is ‘OZNKH’.

Given equation: 6 × 20 ÷ 5 - 20 + 4 = ?

On replacing the symbol:

6 - 20 + 5 × 20 ÷ 4 = ?

→ 6 - 20 + 5 × 5

→ 6 - 20 + 25

→ 31 - 20

→ 11

Hence, answer is ‘11’.

Given equation:

16 - 2 ÷ 40 + 4 × 18 = 40

After interchanging ‘÷ and -’ we get:

L.H.S of equation: 16 ÷ 2 - 40 + 4 × 18 = 40

→ 16 ÷ 2 - 40 + 4 × 18

→ 8 - 40 + 72

→ 80 - 40

→ 40 = R.H.S

Hence, answer is ‘÷ and -’.

The logic/rule followed here is:

1!9 = 20 → (1 + 9) × 2 = 20

9!5 = 28 → (9 + 5) × 2 = 28

5!5 = 20 → (5 + 5) × 2 = 20

7!3 → (7 + 3) × 2 = 20

Hence, answer is ‘20’.

Hence, answer is ‘RRPQPQPQ’.

Hence, the end position is 9 km to the East of the starting position.

Conclusion I: Some ropes are links → True (As, All chains are ropes and Some links are chains)

Conclusion II: All links are ropes → False

Hence, only conclusion I follows.

Hence, G represents Gymnasts who are both Athletes as well as Poets.

The logic/rule/relation followed here is:

Hence, answer is ‘BUN’.

The logic/rule/relation followed here is:

669 - 9 = 660;

660 - 9 = 651;

651 - 9 = 642;

642 - 9 = 633;

633 - 9 = 624

Hence, answer is ‘624’.

The logic/rule/relation followed here is:

1. (49, 45, 39) → 49 - 4 = 45; 45 - 6 = 39

2. (73, 68, 63) → 73 - 5 = 68; 68 - 5 = 63

3. (94, 89, 84) → 94 - 5 = 89; 89 - 5 = 84

4. (66, 61, 56) → 66 - 5 = 61; 61 - 5 = 56

Clearly, (49, 45, 39) does not follows the same pattern as others.

Hence, (49, 45, 39) is the odd one out.

Hence, answer is option ‘3’.

From the figure we can conclude:

1. The face of dice with star will be opposite to the side with circle and square.

2. The side with plus will be opposite the side with circle.

3. The side with four squares will be opposite to the side with five small circles.

Here in the figure above side with four squares and the side with five small circles are adjacent to each other.Hence, it cannot be made based on the unfolded cube in the question figure.

1) 67, 96, 31, 65 → V, O, L, T

2) 20, 89, 14, 59 → B, T, B, X

3) 43, 58, 31, 65 → C, Q, L, T

4) 30, 57, 30, 68 → C, X, C, Q

Hence, answer is ‘67, 96, 31, 65’.

Calculation:

Let the population of both places will be equal in x years

So, according to the question,

96000 - 800x = 68000 + 1200x

⇒ 2,000x = 28,000

∴ x = 14 years

Calculation:

Let the cost of one exam pad be x

And the cost of one pencil be y

According to question

⇒ 3x + 2y = 96      ----(1)

⇒ 4x + 3y = 134    ----(2)

Subtract equation (1) from equation (2) we get

⇒ x + y = 38

So, the total cost of an exam pad and a pencil is Rs. 38.

Given:

 x³ - y³ = 54, x - y = 18 & xy = 2

Calculation:

As we know, x³ - y³ = (x - y) (x² + y² + xy)

⇒ 54 = 18 × (x² + y² + 2)

⇒ 3 = x² + y² + 2

∴ x² + y² = 1

Shortcut Trick

If all 60 animals were penguins (2 feet), the total number of feet would be 60 × 2 = 120.

The extra feet given in the question = 160 − 120 = 40.

Each polar bear contributes an extra 2 feet (since 4 − 2 = 2).

Number of polar bears = Total extra feet ÷ Extra feet per bear = 40 ÷ 2 = 20.

∴ The correct answer is 20 polar bears.

Alternate Method

Given:

⇒ Total number of heads = 60

⇒ Total number of feet = 160

⇒ Feet per penguin = 2

⇒ Feet per polar bear = 4

Method 1: Alligation Approach

⇒ If all animals were penguins, total feet = 60 × 2 = 120.

⇒ If all animals were polar bears, total feet = 60 × 4 = 240.

⇒ The average total feet given is 160.

Penguins (2 feet) Polar Bears (4 feet)

120

240

160

80

40

Ratio → 80 : 40 = 2 : 1

⇒ The ratio of penguins to polar bears is 2 : 1.

⇒ Total ratio parts = 2 + 1 = 3.

⇒ Number of polar bears = (1 ÷ 3) × 60 = 20.

Method 2: Linear Equation

⇒ Let the number of penguins be P and polar bears be B.

⇒ Total heads: P + B = 60     ... (Equation 1)

⇒ Total feet: 2P + 4B = 160

⇒ Dividing by 2: P + 2B = 80     ... (Equation 2)

⇒ Subtracting (1) from (2): (P + 2B) − (P + B) = 80 − 60.

⇒ B = 20.

∴ The correct answer is 20 polar bears.

Additional Information

Heads and Legs Direct Formula

For mixtures of 2-legged and 4-legged animals, the exact number of 4-legged animals can be directly found using: (Total Legs ÷ 2) − Total Heads.

Alligation Cross Method

It is a quick ratio determination technique used when two discrete properties are mixed to produce a known overall average value. Subtract diagonally to find the base ratio components.

Linear Algebraic Elimination

Forming two basic simultaneous equations is a universal rule for standard replacement and count problems to ensure maximum accuracy if shortcuts are forgotten.

Calculation:

We know, two triangles are similar, if their corresponding angles are equal and their corresponding sides are in the same ratio or proportion.

Given, ∠A = ∠D = 80,

But, AB/AC ≠ DE/DF

So, we can say both triangles are not similar.

The SAS similarity criterion refers that If two sides of one triangle are respectively proportional to two corresponding sides of another, and if the included angles are equal, then the two triangles are similar

When two pairs of sides are proportional and one pair of angles are congruent, the angles are not the included angles. This is SSA, which is not a similarity criterion.

Calculation:

We know, the diameter is the largest chord of the circle

If diameter = 6,

So, radius (r) = 3

As we know, OP

 AB (tangent to the circle)

So, in right-angled △OPQ

⇒ OP = 3 (radius of the circle)

⇒ PQ = 4

By Pythagoras theorem

⇒ (OQ)² = (OP)² + (PQ)²

⇒ (OQ)² = 3² + 4²

∴ OQ = 5 cm

Calculation:

Let the income of the R be 100

Income of the Q = 100 × 150/100 = 150

Income of the R = 150 × 150/100 = 225

So, the Income of P is more than R’s income by = (225 - 100)/100 × 100

= 125%

∴ , the Income of P is more than R’s income by 125%

Calculation:

Let us add x to each of the four numbers to make the resulting numbers in proportion

(7 + x)/(17 + x) = (22 + x)/(47 + x)

⇒ (7 + x) (47 + x) = (22 + x)(17 + x) 

⇒ 329 + 7x + 47x + x² = 374 + 22x + 17x + x²

⇒ 15 x = 45

⇒ x = 3

Given:

a mixture of 15% spirit strength be mixed with that of 25% spirit strength to get a mixture of 21% spirit strength

Concept used:

Method of Alligation

Calculation:

Using allegation method

∴ required ratio = 4 : 6 = 2 : 3

Calculation:

The average of three numbers = 58

So, the sum of three numbers = 58 × 3 = 174

Let the third number be 4x

So, the first number = 3x

So, the second number = 4x - 24

According to the question

⇒ 3x + 4x - 24 + 4x = 174

⇒ 11x = 198

⇒ x = 18

So, the first number = 3 × 18 = 54

The second number = 4 × 18 - 24 = 48

∴ The difference between the first number and the second number = 54 - 48 = 6

Calculation:

Principal = 2500 & Amount = 8100

As we know, A = P (1 + r/100)²

⇒ (1 + r/100)² = 81/25

⇒ 1 + r/100 = 9/5

⇒ r = 80%

Amount after 4 years

A = 2500 (1 + 80/100)⁴

⇒ A = 2500 × 9/5 × 9/5 × 9/5 × 9/5

∴ A = 26244

Calculation:

SP of one helmet = 1232

SP of two helmets = 1232 × 2 = 2464

CP of first helmet = 1232 × 100/112 = 1100

CP of second helmet = 1232 × 100/88 = 1400

Total CP of two helmets = 1100 + 1400 = 2500

As we know, loss = CP - SP

∴ Loss = 2500 - 2464 = 36

Calculation:

Let the CP of the table be 100

MP of the table = 100 × 150/100

= 150

If no loss & no profit, then

Discount % = (150 - 100)/150 × 100

= 33.33%

∴ Discount % = 33.33%

Calculation:

To make the perfect square

⇒ 7 × 8 × 9 × 10

⇒ 7 × 2 × 2 × 2 × 3 × 3 × 2 × 5 = 5040

⇒ 5040 is not a perfect square and we know 5041 is a perfect square.

∴  we add 1 in 5040 to make the perfect square.

Calculation:As we know, t₁ × d₁ = t₂ × d₂

So, t₁ = 9 hr, d₁ = 16 days, & d₂ = 24 days

⇒ 9 × 16 = t₂ × 24

∴ t₂ = 6 hr

Given:

speed of first train (S₁) = speed of second train (S₂)

Length of first train = Length of second train = 80 m

Time = 16 sec

Calculation:

If opposite direction, then

Total speed = S₁ + S₂

As we know, speed = distance/time

Total speed = (80 + 80)/16 m/sec

⇒ S₁ + S₂ = 10

⇒ 2S₁ = 10

⇒ S₁ = 5 m /sec

⇒ S₁ = 5 × 18/5 = 18 km/hr

∴  speed of the train is 18 km/hr

Football game is the favourite of most people surveyed (600).

Calculation:

Total number of people who have responded to the survey

⇒ 300 + 600 + 100 + 500 + 300 + 400 + 200

⇒ 2400

Total number of people who have responded to the survey = 2400

We know, total sector 2400 represents = 360°

So, Baseball sector 300 represents = 360°/2400 × 300 = 45°

We know total respondent = 2400

Respondents who say their favourite game is cricket and Hockey = 300 + 500 = 800

∴ Required percentage = 800/2400 × 100 = 33.33%

Calculation:

We know, perimeter of the rectangle = 2 × (Length + Breadth)

Area of the rectangle = Length × Breadth

Given, perimeter of the rectangle = 52 & Breadth = 12

⇒ 2 × (Length + Breadth) = 52

⇒ Length + 12 = 26

⇒ Length = 14

∴ Area of the rectangle = 12 × 14 = 168 cm²

Calculation:

We know, the perimeter of a semicircle = πr + 2r

Given, radius = 7 cm

So, perimeter of a semicircle = 22/7 × 7 + 2 × 7

= 36 cm

∴ The perimeter of a semicircle is 36 cm.

Given:

the curved surface area of the cylinder = 660 cm²

Height of cylinder = 10 cm

Calculation:

We know, the curved surface area of a cylinder = 2πrh

So, 2πrh = 660

⇒ 2 × 22/7 × r × 10 = 660

⇒ r = 21/2

So, diameter of cylinder = 2 × 21/2

= 21 cm

∴ The diameter of the cylinder is 21 cm.

Calculation:

(tan30^o + √3/2) = 1/√3 + √3/2

= (2 + 3)/2√3

= 5/2√3

Given:

 ∠Y = 90°, sec X = 17/8

Calculation:

Sec x = hypotenuse/base = XZ/XY

= 17/8

If XY = 0.8

⇒ 8 unit = 0.8

⇒ 1 unit = 0.1

⇒ (XZ) = 17 unit = 1.7

∴  the length of XZ is 1.7 cm

The correct answer is 0.1.

Key Points

• The mass of the ejected body and the mass of the recoiling body are related to one another by the law of conservation of momentum which is obtained from Newton’s laws of motion.
• According to the law of conservation of momentum, for every action, there is an equal and opposite reaction. Recoiling velocity is an example of this law. From the law, it can be said that
• m₁ v₁ = - m₂ v₂
• m1 and v1 are the mass and velocity of the bullet
• m2 and v2 are the mass and velocity of the gun
• Here m₁= 10g = 0.01 kg, v₁ = 20 m/s and m₂ = 2 kg,

⇒ m₁ v₁ = - m₂ v₂

⇒ 0.01 x 20 = - 2 x v₂

⇒ v₂ = 0.2 / 2 = 0.1 m/s

Note: Recoil velocity will always be negative as the gun will always move in the opposite direction of the fired bullet.

• The statement is from Newton’s Second Law of Motion which states that the rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force.
