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

Conclusions:

I. No L is T → True ( As No T is L means No L is T)

II. Some R are T → False (There is no direct relation between T and R)

Hence, Only conclusion I follow.

Additional Information

The mirror image of this image is:

Hence, option (1) is the correct answer.

Five articles: L, M, P, R, and T.

1. R is just above T and just below P.

2. No article is kept above P.

P > R > T > _ > _

3. L is fourth from the top.

P > R > T > L > _

So, the arrangement is;

P > R > T > L > M

Hence, there are two articles between M and R.

LOGIC: In a row;

(First Number + Second Number) × Third Number = Fourth Number

In Row 1:

(7 + 19) × 12

= 26 × 12

= 312

In Row 2:

(13 + 14) × 19

= 27 × 19

= 513

In Row 3:

(16 + 8) × 11

= 24 × 11

= 264

Hence, "264" is the correct answer.

Six students: H, L, M, R, T, and V.

1. Marks of R are more than only four students.

_ > R > _ > _ > _ > _

2. Marks of L are more than H and V both.

L > H/V

3. Marks of M are more than L but marks of M are not the highest.

M > L

So, possible arrangement is;

T > R > M > L > H/V > H/V

So, the Marks of M and H is not the same as given in the statement.

Hence, option (4) is the correct answer.

1. The sides of the first figure are extended to get the second figure.

• They are one of the most prevalent soil orders in the world.
• It is also called desert soil in some places.
• Following are the important features of arid soil
• ​Mostly, the arid soil is red and brown in color and sandy in texture and by nature, it is saline.
• Owing to the presence of a dry climate and high temperature, evaporation occurs at a faster rate.
• This soil lacks humus and moisture.
• Due to high calcium content, the bottom horizon of this soil is occupied by ‘Kankar’ which restricts the infiltration of water through the soil.
• The soils contain a considerable amount of soluble salts.
• Due to the dry climate and absence of vegetation, it also contains a very low percentage of organic matter.
• The soil is alkaline in nature as there is no rainfall to wash soluble salts.
• These soils are very infertile, but with proper fertilizers and irrigation, the drought-resistant and salt-tolerant dry crops such as barley, cotton, wheat, millets, maize, pulses, etc., can be grown.
• After proper irrigation, this soil becomes cultivable as has been in the case of western Rajasthan.
• Arid soils are most characterized by their water deficiencies, most arid soils contain sufficient amounts of water to support plant growth for no more than 90 consecutive days.
• Arid soils typically contain high levels of calcium carbonates, gypsum, as well as sodium.

Given:

The total number of employees working in a school is 3400

The peons and chef are 55% of the total employees

Concept:

The gain mark percentage = {(Total marks again)/(Total marks)} × 100

Calculation:

Let be assume number of teacher is T

⇒ The number of peons and chef = 3400 × (55/100) = 34 × 55 = 1870

⇒ The total number of teacher T = 3400 - 1870 = 1530

⇒ The teacher less percentage = {(1870 - 1530)/1870} × 100 = (340 × 100)/1870 = (0.1818) × 100 = 18.18%

∴ The required result will be 18.18%.

Given:

⇒ 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + N = 134

⇒ 120 + N = 134

⇒ N = 134 - 120 = 14

∴ The required result will be 14.

Given:

In a company 60% are female and 40% are male

Concept:

Percentage of gain mark = {(Gain marks)/(Total marks)} × 100

Calculation:

Let be assume the total number of employees in a company is 100x

⇒ The male in the company = 100x × (40/100) = 40x

⇒ The female in the company = 100x × (60/100) = 60x

⇒ The number of female from city R = 60x × (15/100) = 9x

⇒ The number of male from city R = 100x × (16/100) = 16x

⇒ The number of male who does not belongs to city R = 40x - 16x = 24x

⇒ The required percentage = (24x/9x) × 100 = (2.6̅ ) × 100 = 266.666%

∴ The required result will be 266.66%.

Given:

The total amount is Rs. 9400

Concept:

If Ax = By = Cz then,

Ax = By = Cz = K     where K is a constant

Calculation:

Let be assume the share of A, B, and C is A, B and C respectively

⇒ 3A = 4B = 5C

⇒ Let be assume 3A = 4B = 5C = K, then 

⇒ A = K/3, B = K/4, and C = K/5

⇒ K/3 + K/4 + K/5 = 9400

⇒ K × (1/3 + 1/4 + 1/5) = 9400

⇒ K × (20 + 15 + 12)/60 = 9400

⇒ K × (47/60) = 9400

⇒ K = (9400 × 60)/47 = 60 × 200 = 12000

⇒ The share of B = K/4 = 12000/4 = 3000

∴ The required result will be 3000.

Given:

The initial speed of the bus is 20 km/hr

Concept:

The sum of the n^th term of arithmetic progression = (The number of term/2) × {2 × (First term) + (The number of terms - 1) × (Common difference)}

Calculation:

Let be assume the first term is 20 km/h and the common difference is 10 km/h and the sum of the terms is 200 km and number of term is N

⇒ 200 = (N/2) × {2 × (20) + (N - 1) × 10}

⇒ 200 = (N/2) × {40 + 10N - 10}

⇒ 200 = (N/2) × (30 + 10N)

⇒ 200 = 15N + 5N²

⇒ N² + 3N - 40 = 0

⇒ N = -8, 5

⇒ The we will take positive value of N = 5

∴ The required result will be 5.

Given:

Given:

Men lose Rs. 88,880 when diamond broke into three parts

Concept:

The price of a diamond ∝ (Weight)²

Calculation:

Let be assume the original weight of the diamond is 25 gram

⇒ The original price of diamond = K × (25)² = 625K

⇒ The diamond has broken into three-part in the ratio = 6 : 8 : 11

⇒ Therefore the weight of the three-part is 6g, 8g, and 11g respectively

⇒ The price of the broken part is 36K, 64K, and 121K respectively

⇒ According to question

⇒ 625K - (36K + 64K + 121K) = 88880

⇒ 625K - 221K = 88880

⇒ 404K = 88880

⇒ K = 88880/404 = 220

⇒ The original price of the diamond = 625K = 625 × 220 = 137,500

∴ The required result will be 137,500.

Calculation:

⇒ 5 + 4 + 7 + A = 16  + A       (Where only  A = 2, 8 is possible)

⇒ 16 + 2 = 18     which is divisible by 6

⇒ 16 + 8 = 24     which is divisible by 6

⇒ The value of A = 2 and 8

∴ The required result will be 2.

Given:

The side of the cube is 198 cm

The height of the circular cylinder is 56 cm

Concept:

The volume of circular cylinder = π × (Radius of the cylinder)² × (Height)

The volume of the cube = (Side)³

Calculation:

Let be assume the radius of the circular cylinder is R

⇒ The volume of cube = (198)³

⇒ The volume of circular cylinder = π × R² × 56

⇒ 2 × (198)³ = (22/7) × 56 × R²

⇒ R² = (2 × 198 × 198 × 198 × 7)/(22 × 56) = (9 × 198 × 198)/(4) 

⇒ R = √(9 × 99 × 99) = 3 × 99 = 297 cm

∴ The required result will be 297 cm.

Given:

⇒ 3/7 = 0.4285

⇒ 6/15 = 0.40

⇒ 9/23 = 0.3913

⇒ 12/31 = 0.3870

⇒ 3/7 > 6/15 > 9/23 > 12/31

∴ The required result will be 3/7.

Given:

The Rohit is 5 times as efficient as Ravi

Concept:

Work = Time × Efficiency

Calculation:

Let be assume the efficiency of Ravi is x and Rohit is 5x and when work is the same then the efficiency is the opposite of the time taken by them

⇒ Time taken by Ravi and Rohit is 5x and x respectively

⇒ 5x - x = 120

⇒ 4x = 120

⇒ x = 120/4 = 30

⇒ The Ravi alone can finish the work = 5x = 5 × 30 = 150 days

⇒ The Rohit can complete the work = x = 30 days

⇒ Both together can complete the work = (1/30 + 1/150) = (5 + 1)/150 = 6/150 = 1/25

⇒ Ravi and Rohit together can complete the work = 25 days

∴ The required result will be 25 days.

Given:

The cost price of 32 chairs of type A is Rs. 992

The cost price of 96 tables of type B is Rs. 3264

Concept:

Profit = Selling price - Cost price

Calculation:

⇒ The cost price of type A chair = 992/32 = 31

⇒ The cost price of type B table = 3264/96 = 34

⇒ The profit earned on the selling of type B table is 50% then selling price of each  type B table = 34 × (150/100) = 51

⇒ The sum of the selling price of type B a chair and a table = 132

⇒ The selling price of a type B chair = 132 - 51 = 81

⇒ The selling price of a type A chair and a type B chair is the same  

⇒ The profit earned on the selling of a type A chair = 81 - 31 = 50

⇒ The profit earned on selling 36 chairs of type A = 50 × 36 = 1800

∴ The required result will be 1800.

Given:

 \(A=\frac{31}{10}\times\frac{3}{10}+\frac{7}{5}\div20\)

\(B=\frac{16-6\times2+3}{23-3\times2}\)

Concept used:

Calculation:

Calculating values

\(A=\frac{31}{10}\times\frac{3}{10}+\frac{7}{5}\div20\)

\(A=\frac{31}{10}\times\frac{3}{10}+\frac{7}{5}\times\frac{1}{20}\)

\(A=\frac{93}{100}+\frac{7}{100} = \frac{100}{100} \)

A = 1

\(B=\frac{16-6\times2+3}{23-3\times2} \)

\(B=\frac{19-12}{23-6}\)

\(B=\frac{7}{17}\)

So now,

A + B = 1 +  \(\frac{7}{17}\)

A + B = 24/17

Given:

The average weight of class A of 24 students is 60 kg

The average weight of class B of 32 students is 75 kg

Concept:

Average = (The sum of all items)/(The total number of items)

Calculation:

⇒ The total weight of class A = 24 × 60 = 1440

⇒ The total weight of class B = 32 × 75 = 2400

⇒ The combine average weight of the class = {(24 × 60) + (32 × 75)}/(32 + 24) 

⇒ (1440 + 2400)/(56) = 3840/56 = 68.5714 kg

∴ The required result will be 68.57 kg.

Given:

The ratio of the cuboid of length, breadth, and height 8 : 5 : 3, respectively 

Total surface area = 3950 cm2

Formula used:

The volume of the cuboid = Length × breadth × height

The total surface area of cuboid (TSA) = 2(lb + bh + hl)

Where, l = length, b = breadth, h = height.

Calculation:

Let the length of cuboid be 8x cm

The breadth of the cuboid be 5x cm

The height of cuboid be 3x cm

According to the question,

The total surface area of cuboid = 2(8x × 5x + 5x × 3x + 8x × 3x)

⇒ 3950 = 2 × 79x2

⇒ x2 = 25

⇒ x = 5 cm

Now,

The length of cuboid = 8x cm = 8 × 5 = 40 cm

The breadth of the cuboid = 5x cm = 5 × 5 = 25 cm

The height of cuboid = 3x cm = 3 × 5 = 15 cm

Again, according to the question,

The volume of the cuboid = 40 × 25 × 15 = 15000 cm3

∴ The volume of the cuboid is 15000 cm3.

The correct answer is 'Bold'.

Key Points

• Let's explore the meaning of the given words and the marked words:
• Confidence: the quality of being certain of your abilities or of having trust in people, plans, or the future.
• Example: He has the confidence to walk into a room of strangers and immediately start a conversation.
• Bold: (of a person, action, or idea) showing an ability to take risks; confident and courageous.
• Example: You should be feeling confident and bold when you meet your bank manager.
• Therefore, the correct answer is option 2.

Additional Information

• Fine: good or good enough; healthy and well.
• Example: I felt terrible last night but I feel fine this morning.
• Loose: not firmly held or fastened in place.
• Example: There were some loose wires hanging out of the wall.
• Diffident: modest or shy because of a lack of self-confidence.
• Example:You shouldn't be so diffident about your achievements - you've done really well!

The correct answer is 'A cup of coffee.'

Key Points

• Cup of Joe: It is an idiomatic phrase that means a cup of coffee.
• Example: I can't even function in the morning until I've had my first cup of joe.
• Thus, from above we can say that the correct answer is option 2.

The correct answer is 'over'.

Key Points

• Blow over: It is a phrasal verb which means to pass by or to end.
• Example: We hope that this crisis will soon blow over.
• Thus, 'over' will be used in the blank.

Therefore, the correct answer is 'The cloud of misfortunes was blown over.' 

Additional Information

• Phrasal verb: A phrasal verb is a combination of words (a verb + a preposition or verb + adverb) that when used together, usually take on a different meaning to that of the original verb.  
• Blow out: to disappoint someone by not meeting them or not doing something that you had arranged to do together.
• Example: She was supposed to go to that party with me, but she blew me out.
• Blow away: to surprise or please someone very much.
• Example: The ending will blow you away.
• Blow off: to treat something or someone as if that thing or person were not important.
• Example: Just blow off his comments, he's only joking.

The correct answer is 'at'.

Key Points

• The error lies in the incorrect usage of prepositions.
• 'For' needs to be replaced with 'at'.
• For: As a preposition, it is used to say who is intended to get or use something, or where something is intended to be used.
• Example: I’ve got a present for you.
• At: As a preposition, it is used to say exactly when something happens.
• Example: The film starts at 8 o'clock.

Therefore, the correct answer is: 'The party starts at 8:00 pm.' 

Additional Information

• Preposition: in grammar, a word that is used before a noun, a noun phrase, or a pronoun, connecting it to another word.

The correct answer is 'QSRP'.

Key Points

• Statement Q will be the first in sequence as it is introducing the subject of the sentence i.e. ' steady cycling'.
• Statement S will follow Statement Q as it connects the noun with its verb 'burns' which is singular since the subject i.e. 'cycling' is also singular and will take a singular verb.
• Statement R will follow statement S as it states how many calories can a person burn with the help of cycling.
• Statement P will be the last part.

Therefore, the correct sequence is QSRP

• Sequence:
• Q : steady cycling
• S : burns approximately
• R : 300 calories
• P : per hour

The correct answer is 'cheerful persons', i.e. the error lies in this part of the sentence.

Key Points

• The error lies in the incorrect usage of noun.
• 'Persons' needs to be replaced with 'person'.
• The article used in the sentence i.e.'a' is used before a singular noun which gives a general idea.
• Thus, the usage of the plural noun 'persons' is incorrect here.

Therefore the correct sentence is: 'It is a pleasure to meet a cheerful person.' 

Additional Information

• Article: Articles are words that define a noun as specific or unspecific.
• The definite article is the word the. It limits the meaning of a noun to one particular thing.
• Example: Please give me the red hammer, the blue one is too small.
• The indefinite article indicates that a noun refers to a general idea rather than a particular thing. The indefinite article takes two forms. It’s the word a when it precedes a word that begins with a consonant. It’s the word an when it precedes a word that begins with a vowel.
• Example: 
• Please hand me a book; any book will do.
• Please hand me an autobiography; any autobiography will do.

The correct answer is 'Presently'.

Key Points

• Presently: at the present time; now.
• Example: He is presently staying with us.
• Since the context of the sentence is expressing that right now, she is busy studying for her exams.
• Thus, the correct answer is 'option 1'.

Therefore, the correct sentence is: 'Presently, she is busy studying for her exams.'

Confusion Points

• There can be confusion between the usage of 'At present' and 'presently'.
• At Present: It refers to the events or activities that are taking place 'right now' or 'in the present moment'.
• Example: I am eating at present.
• Presently: It refers to the events or activities that are taking place right now and will continue happening in the immediate future.
• Example: John is presently away on the business.
• Since studying for exam is a process that is happening right now and will continue happening in the immediate future, therefore, we will use 'presently' in place of 'at the present'.
• Thus, the correct answer is option 1.

The correct answer is 'Considering Everything.'

Key Points

• All in all: It is an idiomatic phrase that means used to show that you are considering every part of a situation.
• Example: All in all, it had been one of the most miserable days of Henry’s life.
• Thus, from above we can say that the correct answer is option 1.

The correct answer is 'Influence'.

Key Points
