DSSSB PRT Official Paper 14 Nov 2019 Shift 1 (Previous Year Paper)

Six boys J, K, L, M, N, and P are sitting around a circular table facing towards the centre. 

i) J is second to the left of P.

ii) N is the immediate neighbour of P and J. (This means N is sitting between P and J)

iii) K is second to the right of N.

iv) L is to the immediate to the left of M.

The arrangement will be:

Thus we can say L is third to the left of N.

Hence, the correct answer is "L".

Note: Two opposite faces are never seen together or adjacent to each other:

In Figure, I:- L and T are opposite faces but here they are seen together which is wrong. Thus this cube cannot be made.

In Figure II:- K and 7 are opposite faces but here they are seen together which is wrong. Thus this cube cannot be made.

In Figures III:- None of the opposite faces are seen together nor they are adjacent to each other.

Thus Figures III can be formed by folding the dice.

Hence, the correct answer is "Only III". 

Additional Information

• Dices are of two types :

1. Standard Dice
2. Non-Standard Dice.

• Dice has:-

1. faces = 6
2. sides = 12
3. corners = 8

• Two opposite faces never seen together.
• Adjacent faces are never opposite to each other.

The logic followed is:

Height of 8 boys B1, B2, B3, B4, B5, B6, B7, and B8 are compared.

i) Height of B4 is more than B6.

B4 > B6 equation i)

ii) Height of B8 is less than only 3 boys.

iii) Height of B2 is more than B1 but less than B8.

B8 > B2 > B1 equation ii)

iv)  If the height of B4 is less than B1

B1 > B4 equation iii)

v) B5 and B7 are taller than B8 but shorter than B3.

From the equation i) and iii) we can say,

B6 is the smallest of all. Thus we can conclude from the given statement i.e the height of B3 will be the least or maximum. As B6 is the smallest, it is only possible B3 is the maximum in height.

Thus the final arrangement is:

B3 > B5 = B7 > B8 > B2 > B1 > B4 > B6 

Hence, the correct answer is "Option 3".

As per the given information;

Clockwise Direction = 194° + 612° = 806° 

Anticlockwise Direction = 263° + 342° = 605° 

Difference = 806° - 605° = 201° (Clockwise)

Hence, the minute is in the North West direction initially.

The least possible Venn diagram for the given statements is as below:

Conclusions: 

1. Some red are pink → False (It is possible but not definite). 2. No red is blue → False (As some Blue are Red, then some Red are Blue will also be a definite conclusion).

Hence, the correct answer is "Neither conclusion I and II follows".

Additional Information

The least possible Venn diagram for the given statements is as below:

Conclusions: 

1. Some J are not M → True (As no M is J then some J are not M will also be a definite conclusion). 2. Some M are A → False (It is possible but not definite). 3.  No K is A → False (As some A is K then some K is A also a definite conclusion).

Hence, the correct answer is "Only conclusion I follows ".

Additional Information

The pattern followed is:

Hence, the correct answer is "JTCD".

Cricket is played with a bat. Football is another sports played with a ball.

The pattern followed is:

The given series is a Fibonacci series.

To complete the Fibonacci series 32 must be replaced by 34.

Thus the wrong term is 32. Instead of 32 there should be 34.

Hence, the correct answer is "Option 2".

According to the information given in the question, we can draw the following diagram.

Thus point J is in a Northeast direction from point P.

Mistake PointsHere in the question it is asked:

• In which direction is point J from point P means J direction w.rt to P which is Northeast
• Here in the question it is not asked In which direction is point P from point J.

Hence, the correct answer is "Northeast".

The logic follows here is:

The cluster follows the pattern of +3, +3 except for option (4) which follows the pattern of +4, +3.  

Option 1 → 

Option 2 → 

Option 3 → 

Option 4 → 

Thus we can see LPS doesn't follow the pattern of +3, +3.

Hence, the correct answer is "LPS".

The least possible Venn diagram for the given set of words is:

Hence, the correct answer is Option 3.

The pattern followed is:

Similarly,

Hence, the correct answer is "MIG : SDO".

The embedded part of this image is:

Hence, Option (3) is the correct answer.

The logic followed is:

Thus code for "is" can be either 7 or 4 but in option (7 is not mentioned.) This means we left with only 4.

Thus the code for "is" is 4.

Hence, the correct answer is "4".

Six persons: G, H, R, T, U, and V.

Six Cars: C1, C2, C3, C4, C5, and C6.

1) T likes C3.

2) V and G don’t like C1 and C2.

3) R likes either C6 or C2.

4) H doesn’t like C5.

5. U likes either C2 or C6.

As G and R do not like C1.

So, H likes C1 and G and V either likes C4 or C5

Possible cases are;

U likes either C2 or C6 and V likes either C4 or C5.

1. C2, C4

2) C2, C5

3. C6, C4

4. C6, C5

Hence, option (1) is the correct answer.

The logic followed is:

second number = (first number)² - 4

140 = 12² - 4

140 = 144 - 4

140 = 140

Similarly,

? = 29² - 4

? = 841 - 4

? = 837

Hence, the correct answer is "837".

The pattern followed is:

Hence, the correct answer is "PD17".

In each step bottom figure moved to top.

Step 1:

Step 2:

Step 3:

Step 4:

The correct figure is;

Hence, option (2) is the correct answer.

The logic followed here is:

Plastic who is table shows through the shaded area in the diagram below:

Plastic are table = 12 + 4 = 16

Given:

5 men can complete a work in 40 days

6 women can complete the same work in 30 days

Concept:

(Men₁ × Days₁ × Hours₁)/W₁ = (Men₂ × Days₂ × Hours₂)/W₂

Calculation:

Let be assume 20 men and 18 women can complete the work in X days

⇒ The efficiency of men = 1/(5 × 40) = 1/200

⇒ The efficiency of women = 1/(6 × 30) = 1/180

⇒ (20X/200) + (18X/180) = 1

⇒ X/10 + X/10 = 1

⇒ (X + X)/10 = 1

⇒ 2X = 10

⇒ X = 5

∴ The required result will be 5.

Given:

The total number of votes is 1600

The 15% of total votes are invalid

Concept:

Percentage of gain marks = {(The gain marks)/(The total number of marks)} × 100

Calculation:

⇒ The total number of votes = 1600

⇒ The total number of valid votes = (100 - 15)/100  × (1600) = (85/100) × 1600 = 16 × 85 = 1360

⇒ The candidate P reciecved the votes = (45/100) × 1360 = 612

⇒ The candidate R received the votes = (25/100) × 1360 = 340

⇒ The R received less than votes from P = 612 - 340 = 272

∴ The required result will be 272.

Given:

The total rupees is Rs. 240

Concept:

The total rupees = (Number of coins) × (The value of the coin)

Calculation:

Let be assume each number of the coin is x

⇒ 240 = x + 2x + 5x

⇒ 8x = 240

⇒ x = 240/8 = 30

⇒ The total number of coin = 3 × 30 = 90

∴ The required result will be 90.

√12 + √3, √11 + 2, √5 + √10 and 1 + √14

Concept:

If A is greater than B then A > B

Calculation:

⇒ √12 + √3 = 3.46 + 1.73 = 5.19

⇒ √11 + 2 = 3.31 + 2 = 5.31

⇒ √5 + √10 = 2.23 + 3.16 = 5.39

⇒ 1 + √14 = 1 + 3.74 = 4.74

⇒ (√5 + √10) > (√11 + 2) > (√12 + √3) > (1 + √14)

∴ The required result will be (√5 + √10).

⇒ If we will put the value of N then the given number will be divisible by 8

∴ The required result will be 4.

Given data :

ratio of total number of students appeared in year Y1 and Y3 = (3000 + 4200)

⇒ 7200

total number of students appeared in all the five years together = (3000 + 4000 + 4200 + 5000 + 6000)

⇒ 22200

according to the question:

Required ratio = 7200 : 22200

⇒ 36 : 111

Given:

The sum is 14000 and time is 9 year

The rate is 14%

Concept:

Simple interest = (Principle × Rate × Time)/100

Calculation:

⇒ The simple interest = (14000 × 14 × 9)/100 = 140 × 14 × 9 = 1960 × 9 = 17640

∴ The required result will be 17640.

Given:

The diameter of the wheel of a cycle is 21 cm or 0.21 m

The speed of cyclist is 72.6 km/h

The time taken by the cyclist to complete the journey is 150 minutes or 9000 seconds

Concept:

The circumference of the wheel = 2 × π × (The radius of the circle)

Distance = Speed × Time

Calculation:

⇒ The total distance covered by cyclists = 9000 × 72.6 × (5/18) = 500 × 72.6 × 5 = 2500 × 72.6 = 181500 m

⇒ The cyclist can cover the distance in one round of wheel = 2 × (22/7) × (The radius of the wheel)

⇒ 2 × (22/7) × (0.21/2) = 44 × (3/200) = 0.66 m

⇒ The total rounds taken by cyclist = 181500/0.66 = 275000

∴ The required result will be 275000.

Given:

Loss of Raman = 16.66%

Profit of Rajat = 50%

The selling price of both articles = Rs 1200

Formula Used:

Profit% = (SP - CP)/CP × 100

Loss% = (CP - SP)/CP × 100

where CP → Cost Price, SP → Selling Price

Calculations:

Cost Price of Raman be "A"

16.66% = (A - 1200)/1200 × 100 (Base will be 1200 Since Raman calculates profit/loss on selling price)

A = 1400

Cost Price of Rajat be "B"

50% = (1200 - B)/B × 100

B = 800

Required Percentage = (Cost price of Raman’s/cost price of Rajat’s article) × 100 

= (1400/800) × 100

= 175%

Given:

The first 14 positive odd number

Concept:

The sum of first n positive odd number = n × n = n²

The average = (The sum of all numbers)/(The total numbers)

Calculation:

⇒ The sum of first positive odd number = 14 × 14 = 196

⇒ The average of the numbers = 196/14 = 14

∴ The required result will be 14.

Given:

Two-digit numbers

Concept:

Calculation:

Let be assume the first term is 10 and the last term is 95 which is divisible by 5 and the common difference is 5 and the total term is n

⇒ The number two-digit numbers is divisible by 5 

⇒ 95 = 10 + (n - 1) × 5

⇒ n = 18, So 18 numbers of two-digit is divisible by 5

⇒ The total two-digit number = 90

⇒ The two-digit number which is not divisible by 5 = 90 - 18 = 72

∴ The required result will be 72.

Given:

The speed of man is 30 km/h and 3 km/h respectively

Concept:

Distance = Speed × Time

Calculation:

Let be assume the distance is D

⇒ D/30 + D/3 = 22

⇒ D + 10D = 30 × 22

⇒ 11D = 30 × 22

⇒ D = 30 × 2 = 60

Total distance = 60×2

⇒ 120

∴ The required result will be 120.

Given data :

⇒ 0.4235 × 100

⇒ 42.35 %

Shortcut Trick

Profit Ratio = (9 × 4) : (6 × 12) : (15 × 8)

Ratio (Rahul : Raman : Mohan) = 36 : 72 : 120 = 3 : 6 : 10

Total Ratio parts = 3 + 6 + 10 = 19

19 units → Rs 57,000

Mohan share (10 units) = (57,000 ÷ 19) × 10 = 30,000

∴ The correct answer is Rs 30000.

Alternate Method

Given:

Rahul investment = Rs 9,000 for 4 months

Raman investment = Rs 6,000 for 12 months

Mohan investment = Rs 15,000 for 8 months (12 − 4 = 8)

Total Profit = Rs 57,000

Formula Used:

Profit Share Ratio = (Capital₁ × Time₁) : (Capital₂ × Time₂) : (Capital₃ × Time₃)

Partnership Investment Distribution (Capital × Time)

9k × 4m Rahul

6k × 12m Raman

15k × 8m Mohan

Calculations:

⇒ Ratio of Profit = (9000 × 4) : (6000 × 12) : (15000 × 8)

⇒ Ratio of Profit = 36000 : 72000 : 120000

⇒ Dividing each term by 12000:

⇒ Ratio = 3 : 6 : 10

⇒ Total ratio parts = 3 + 6 + 10 = 19

⇒ 19 units = 57,000

⇒ 1 unit = 57000 ÷ 19 = 3,000

⇒ Mohan's share = 10 × 3,000 = 30,000

∴ The correct answer is Rs 30000.

Additional Information

Capital and Time Relationship

Profit is directly proportional to both capital and time. If time is equal for all, profit ratio equals capital ratio.

Compound Partnership

When partners invest for different time periods, it is called a compound partnership. Use Profit₁ : Profit₂ = C₁T₁ : C₂T₂.

Investment Calculation

Capital = Profit ÷ Time. This is used to find the investment when profit and time ratios are given.

Given:

The present age of the father and his son is 110

The ratio of age of father and son 5 years ago is 7 : 3

Concept:

If the sum of the age of A and B is X then the age of A is (X - B) and age of B is (X - A)

Calculation:

Let be assume the present age of father is F and the present age of son is S

⇒ F + S = 110  ..... (1)

⇒ (F - 5)/(S - 5) = 7/3 ..... (2)

⇒ By equation (1) and (2)

⇒ (F - 5)/(110 - F - 5) = 7/3

⇒ F = 75 and S = 35

⇒ Ratio of the age of father and son after 20 year = (75 + 20)/(35 + 20) = 95/55 = 19/11

∴ The required result will be 19/11.

Given:

Area of rectangle = 3888 cm2

Ratio of length and breadth of a rectangle = 4 : 3

Concept Used:

Perimeter of Rectangle = Perimeter of Semicircle

Formulae Used:

Area of Rectangle = Length × Breadth

Area of Semicircle = π(Radius)²/2

Perimeter of Semicircle = (π + 2)Radius

Perimeter of Rectangle = 2(Length + Breadth)

Calculations:

Let the length of the rectangle be 4x and breadth be 3x

So, According to question

3888 = 4x × 3x = 12x²

x² = 3888/12 = 324

x = 18

Length = 72, breadth = 54

Perimeter of Rectangle = 2(72 + 54) = 252 cm

252 = (π + 2)Radius

Radius = 49

Area of Semicircle = π(49)2/2

Area of Semicircle = 3773 cm²

Given: 

Number of wathces repaired D1 = 18

Number of wathces repaired D3 = 27

Number of wathces repaired D4 = 30

Number of wathces repaired D5 = 32

Calculation:

According to the question,

E, D3 and D5 represent the total number of watches repaired in a day,

Then, total watches repaired by E = D3 + D5 = 27 + 32 = 59

Again,

F, D1 and D4 represent the total number of repairs in the day, 

Then, total watches repaired by F =  D1 + D4 = 18 + 30 = 48

Required Percentage = (59/48) × 100 = 122.91%

∴ E is 122.91% of F

Given:

Sides of the plot = 24 m, 10m, 15 m and 15 m

Angle between two sides = 90

Formulae used:

Pythagoras Theorem

 (Hypotenuse)2 = (Perpendicular)2 + (Base)2

Herons’ Formulae 

Area of Triangle = \( √ {s\left( {s - a} \right)\left( {s - b} \right)\left( {s - c} \right)} \)

Where "s" is semi perimeter = (a + b + c)/2

Calculation:

Cosidering ABCD as the plot,

AB = 24 m

AD = 10 m

BC = CD = 15 m

Area of plot = Area of ∆ABD + Area of ∆BCD

Area of ∆ABD = 24 × 10/2 = 120 m²

Area of ∆BCD will be calculated using Heron's formulae

s = (15 + 15 + 26)/2 = 28

Area of ∆BCD = \( √ {28\left( {28 - 15} \right)\left( {28 - 15} \right)\left( {28 - 26} \right)} \)

Area of ∆BCD = \( √ {28\left( {13} \right)\left( {13} \right)\left( {2} \right)} \) = 26√14 m²

Area of plot = (120 + 26√14) m2

Given:

\(A = \frac{5+6-7 \times 2 \div 5 + 8 \div10}{3}\)

\(B = \frac{8+5-6 + 8+ 3}{3}\)

Concept used:

Calculation:

Calculating

\(A = \frac{5+6-7 \times 2 \div 5 + 8 \div10}{3}\)

\(A = \frac{5+6-\frac{14}{5} + \frac{4}{5}}{3}\)

\(A = \frac{5+\frac{16}{5} + \frac{4}{5}}{3}\)

\(A = \frac{9}{3}\) = 3

and

\(B = \frac{8+5-6 + 8+ 3}{3}\)

\(B = \frac{8-1 + 8+ 3}{3}\)

\(B = \frac{7 + 8+ 3}{3}\)

\(B = \frac{18}{3}\) = 6

So,

A + B = 9

The correct answer is 'for finish the work ', i.e. the error lies in this part of the sentence.

Key Points

• The error lies in the incorrect usage of the preposition 'for'.
• 'for' needs to be replaced with 'to'.
• When there are two verbs in a sentence, the second verb is used with the preposition 'to'.
• Example: He wants to go home.
• Thus, the correct answer is option 3.

Therefore, the  correct sentence is: 'The editor gave him the deadline to finish the work.'

The correct answer is 'SQPR'.

Key Points

• Statement S will be the first in sequence as it is introducing the subject of the sentence i.e. 'Sunderban tigers'.
• Statement Q will follow Statement S as it connects the subject i.e. 'sunderban tigers' with its linking verb 'are'.
• Statement P will follow statement Q as it the problem that the 'sunderban tigers' are facing.
• Statement R will be the last part.

Therefore, the correct sequence is SQPR

• Sequence**:**
• S: sunderban tigers
• Q: are facing
• P: shortage of a
• R: natural fodder

The correct answer is 'had died'.

Key Points

• The error lies in the incorrect usage of the verb 'died'.
• 'Died' needs to be replaced with 'had died'.
• The given sentence is an example of the past perfect tense.
• Past perfect tense: The past perfect, also called the pluperfect, is a verb tense used to talk about actions that were completed before some point in the past because of this it is called past of past.
• Structure:
• Subject + had + the third form of verb.
• Example: Paul tried to hide the vase because he had broken it.
• Thus, from above we can conclude that the correct answer is option 4.

Therefore, the correct sentence is: 'The lady had died before she reached the hospital.'

The correct answer is 'Immoral'.

Key Points

• Immoral: applies to one who acts contrary to or does not obey or conform to standards of morality.
• Example: It’s immoral to be rich while people are starving and homeless.
• Thus, the correct answer is option 4.

Additional Information

• Let's explore the other options:

The correct answer is 'No error'.

Key Points

• There is no error in the given statement or we can say that this statement is grammatically and contextually correct.
• In the part, A of the sentence the usage of the verb 'is' is correct as the subject i.e. 'news' is a collective noun and collective nouns are generally treated as singular which means they take singular verb after them.
• 'Too good to be true': This clause is in the structure: too+ adjective+to-infinitive and is therefore correct.
• Thus, this question requires no improvement.

Additional Information

• Collective noun: A collective noun is a word or phrase that refers to a group of people or things as one entity.

The correctly spelt word is 'Conscience'.

Key Points

• Conscience: the part of your mind that tells you whether what you are doing is morally right or wrong.
• Example: Well, at least I can face them all with a clear conscience (=the knowledge that you have done nothing wrong).
• Thus, we can conclude the correct answer is option 3.
• Let's explore the correct spelling of other options:
• Height: the topmost point of anything
• Fiery: consisting of fire or burning strongly and brightly.
• Existence: The fact or state of living or having objective reality.

The correct answer is 'to'.

Key Points

• Date back to: It is an idiom which means to have been made in or to have come into being in (a certain time in the past).
• Example: They found jewelry dating back to the 1700s.
• Thus, 'to' will be used in the blank.

Therefore, the correct sentence is: 'The origin of ice-cream dates back to nearly half-a-century.'

The correct answer is 'Avoid'.

Key Points

• Let's explore the meaning of the marked word and the given word.
• Forgo: to not do or have something pleasant or enjoyable.
• Example: I had to forgo lunch.
• Avoid: to stay away from someone or something, or not use something.
• Example: Everyone seemed to be avoiding Nick.
• From above, we can refer that the correct answer is option 3.
