The Venn diagrams best represent the relationship between - Sports, Cricket, Football figures are shown below:

Both Cricket and Football are comes under the category of Sport but the Cricket and Football are different types of sports so they are separated here.

Hence, correct answer is Option 4.

The Venn diagrams best represent the relationship between - Year, Decade, Century figures are shown below:

1 Decade  = 10 Years so the year comes under the Decade.

1 Century = 10 Decade so the decade comes under the Century.

Hence, Correct answer Option 2.

The diagrammatic representation of the given information is as follows:

The distance between A and E are as follows:

Applying Pythagoras theorem:

AE² = (Vertical Distance between AE)² + (Horizontal Distance between AE)2 = 20² + 25²

AE² = 400 + 625 = 1025 = (25 × 41)

AE = 5√(41) km.

The shortest distance between A and E is 5√(41) km.

Hence, the correct answer is "5√(41)".

BODMAS RULE:

By decoding given information :

Given: 135 ! 3 & 45 $ 4 @ 167

After interchanging the symbol;

135 ÷ 3 - 45 × 4 + 167

Using BODMAS rule, 

= 45 - 45 × 4 + 167

= 45 - 180 + 167

= 45 + 167 - 180

= 212 - 180

= 32.

Hence, "32" is the correct answer

1. Given expression: 24 A 3 B 2 C 2 D 8 = 22

Letters interchanging with signs:

= 24 × 3 + 2 ÷ 2 - 8

= 24 × 3 + 1 - 8

= 72 + 1 - 8

= 73 - 8

= 65 ≠ RHS

2. Given expression: 24 A 3 B 2 C 2 D 8 = 22

Letters interchanging with signs:

= 24 × 3 - 2 ÷ 2 + 8

= 24 × 3 - 1 + 8

= 72 - 1 + 8

= 80 - 1

= 79 ≠ RHS

3. Given expression: 24 A 3 B 2 C 2 D 8 = 22

Letters interchanging with signs:

= 24 ÷ 3 × 2 - 2 + 8

= 8 × 2 - 2 + 8

= 16 - 2 + 8

= 24 - 2

= 22 = RHS

4. Given expression: 24 A 3 B 2 C 2 D 8 = 22

Letters interchanging with signs:

= 24 × 3 ÷ 2 + 2 - 8

= 24 × 1.5 + 2 - 8

= 36 + 2 - 8

= 38 - 8

= 30 ≠ RHS

Hence, the correct answer is " ÷, ×, -, +".

Position values of the letters according to the English alphabet series.

Here, In all options except option 4, 1^st and 2^nd elements are both prime numbers and the 3^rd element is the sum of them.

Option (1): BCE → B = 2, C = 3 and 2 + 3 = 5 ⇒ E

Option (2): EGL → E = 5, G = 7 and 5 + 7 = 12 ⇒ L

Option (3): GKR → G = 7, K = 11 and 7 + 11 = 18 ⇒ R

Option (4): JKU → J = 10, K = 11 and 10 + 11 = 21 ⇒ U

Here, in Option (4), J is not a prime number.

Hence, the correct answer is "JKU".

The given Figure-

The Number Common in the circle, triangle and trapezium = 5

Key Points

• The part C of the given sentence is erroneous because the word 'should' is not grammatically correct for this sentence.
• The given is a positive statement and a tag question is used in this sentence.
• The tag question should be negative as the given is a positive statement.
• Therefore, 'shouldn't' is the correct form.

• Hence, we need to replace 'went' with 'go' to make it grammatically correct.
• ​​Correct sentence: Suman could not go to picnic, because her mother was not well.

• Main verb के साथ लगभग हमेशा Could not प्रयोग किया जा सकता है।
• Example: Sorry, I could not call you last week.
• इसलिए, हमें इसे व्याकरण की दृष्टि से सही बनाने के लिए went  को go से बदलना होगा।

The correct answer is option 1 i.e. error lies in 'If parents could be physically in the'

Key Points 

• In Option 1 the usage of 'could be' is wrong Instead use 'were'
• We can't use could, would, and Should in the subordinate clauses.
• Let's see an example for more clarity:
• If I had lunch with my favorite actress, I could ask for her autograph. ('had' in this sentence is used as past subjunctive mood)

The correct sentence is: If parents were physically in the same place as their children, they could simply carry on working as normal.

• So we need to use 'were' with the subject I instead of 'was'.
• Thus option 2 is the correct answer.

The correct sentence is**:** I wish, I were a king.

Additional Information 

• Let's understand the meaning of the subjunctive mood/subjunctive sentences:
• The subjunctive refers to words that describe doubtful situations—like wishes for things that aren’t real. Here the verb deals with hypothetical situations or with ideas that are contrary to real facts.
• Example: I wish I were older. (Here the speaker is actually not an older person.)

The correct answer is- 'of.'

Key Points

• The correct preposition to fill in the blank is 'of.'
• The preposition 'of' is used to *connect particular adjectives (*full) and verbs with nouns (excitement).
• Example: Sarita is fond of swimming.
• Hence option 4 is the correct answer.

The correct sentence will be: The stories in Arabian Nights are really full of excitement.

Additional Information

• Let's learn the use of other given options:
• With: used to say that people or things are in a place together or are doing something together; using something
• Example: He lives with his grandmother.
• For: having the purpose of
• Example**:** This pool is for the use of hotel guests only.
• By: used to show the person or thing that does something
• Example**:** The motorcycle was driven by a tiny bald man.

The correct answer is- 'Peaceful days' 

Key Points

• The most appropriate meaning of the given idiom 'Halcyon days​​​' is 'Peaceful days'.
• Let’s look at the meaning and example of the given phrasal verb:
• Halcyon days​​​- "a fortnight of calm weather during the winter solstice".(शीतकालीन संक्रांति के दौरान शांत मौसम का पखवाड़ा)
• E.g. They were the halcyon days of apprenticeships for huge numbers of our young people.
• ​​Thus from the explanation given above, we find that the 2nd option is the correct choice.

The correct answer is- 'Commercial.'

Key Points

• An adjective adds a description to a person, animal, place, or thing or tells the noun's number or quantity.
• Example: My younger brother is the most troublesome of the lot.
• Adjectives are formed by adding -y, -al, -ial, -ly, -ish, -ous, -some, -able, -full, -ic, -able, -less, -ing or -ive as a suffix to nouns or verbs.
• The adjective form of the noun commerce is formed by replacing '-e' with '-ial.'
• So commercial is the adjective form of the noun commerce.

<br>

Thus the correct answer is option 1.

Additional Information

Let's learn about the other given options:

• Commercialize - Verb
• Commercially - Adverb
• Commercialism - Noun

Given:

15% of 25% of 35% of 100 = ?

Concept Used:

x% of y = xy/100

Calculation:

We have 15% of 25% of 35% of 100 = ?

⇒ $\frac{15}{100} \times \frac{25}{100} \times \frac{35}{100} \times 100 = ?$

⇒ $\frac{13125}{10000} = ?$

⇒ 1.3125 = ?

∴ The required value of '?' is 1.3125

Shortcut Trick

Alligation Method 

 

From the above figure we can write 

1st Cat students : 2nd Cat. students = 0.6 : 0.4

∴ The required ratio is 3 : 2.

Alternate Method

Given:

The average weight of 1st category students = 15.2 

The average weight of 2nd category students = 14.2 

Formula Used: 

Average = Sum of observations/ Number of observations 

Sum of observations = Average × Number of observations 

Calculation:

Let the number of students of 1st and 2nd category be x and y respectively

Now, According to the formula used

Students in 1^st category = 15.2 × (x) = 15.2x    ----(i)

Students in 2^nd category = 14.2 × (x) = 14.2x     ----(ii)

Students of both category = 14.8 × (x + y)    ----(iii)

From (i), (ii) and (iii), we get 

15.2x + 14.2y = 14.8(x + y)

⇒ 15.2x - 14.8x = 14.8y - 14.2y

⇒ 0.4x = 0.6y 

⇒ x/y = 0.6/0.4

⇒ x : y = 3 : 2

∴ The correct answer is option 1.

Given: 

Principle = Rs. 540 

Amount = Rs. 693 

Time = 20 month = 20/12 years

Formula Used:

S.I = PRT/100 

A = P + S.I

Where, S.I = Simple Interest, P = Principal

R = Rate, T = Time, A = Amount

Calculation: 

Form given formula 

S.I = A - P

⇒ S.I = 693 - 540 = 153 

Now, According to the formula used

$153 = \frac{540 \times \frac{20}{12}\times R}{100}$

⇒ $R = \frac {153 \times 100 \times 12}{540 \times 20}$

⇒ R = 17% 

∴ The required rate percent is 17%.

Given:

Amount at the end of 2 years = Rs 14,520 

Amount at the end of 3 years = Rs 15,972 

Formula Used:

In case of compound interest

A = P(1 + R/100)ⁿ

Where, A = Amount, P = Pruincipal

R = Rate percent, n = Time in years

Calculation:

According to the question 

14,520 = P(1 + R/100)²      ----(1)

15,972 = P(1 + R/100)³      ----(2)

On dividing (2) by (1), we get 

⇒ 15,972/14520 = 1 + (R/100) 

⇒ 1.1 = 1 + R/100 

⇒ R = 10% 

Put the value of R in equation (1)

14,520 = P(1 + 10/100)2 

⇒ P = (14520 × 10 × 10)/121

⇒ 12000 

∴ The required sum is Rs. 12000.

Given:

Amount (A) = Rs 1,94,481 

Time (n) = 2 years

Rate of Interest (R) = 10% 

Formula Used:

In case of compounded half yearly 

A = P(1 + R/200)²ⁿ

Calculation: 

According to the question

194481 = P(1 + 10/200)⁴

⇒ 194481 = P × (21/20) × (21/20) × (21/20) × (21/20) 

⇒ P = 194481 × (160000)/(9261 × 21) 

⇒ P = 1,60,000

∴ The value of the sum is 1,60,000.

Given: 

The ratio of Copper and Aluminium in original composition = 3 : 2

The ratio of Copper and Aluminium in the final composition = 2 : 3

Calculation: 

Let the amount of Copper in the original composition be 3x

Let the amount of Aluminium in the original composition be 2x

According to the question 

When 25 kgs of the alloy are taken out

The remaining amount of Copper = 3x - 25 × (3/5)

⇒ 3x - 15        ----(1)

The remaining amount of Aluminium = 2x - 25 × (2/5)

⇒ 2x - 10 

So, The amount of Aluminium in the new composition = 2x - 10 + 25

⇒ 2x + 15       ----(2)

Now, From (1) and (2) and according to the question

⇒ $\frac {3x - 15}{2x + 15} =\frac {2}{3}$

⇒ 9x - 45 = 4x + 30

⇒ 5x = 75

⇒ x = 15

Now, Original weight of alloy = 3x + 2x 

⇒ 5x = 5 × 15 = 75

∴ The original weight of alloy is 75 kgs.

Given 

The ratio of S.P of three articles = 40 : 37 : 46

The ratio of profit% = 5 : 4 : 7.

The cost price of third article = 480

Formula Used 

Profit = Selling Price - Cost Price 

Profit% = [(S.P - C.P)/C.P] × 100

Calculation 

Let the S.P. of three articles be 40x, 37x and 46x respectively 

The profit% of three articles be 5y%, 4y% and 7y%

Now, According to the question 

For 3^rd Article 

7y/100 = [46x - 480]/480

⇒ 336y = 460x - 4800      ----(i)

For 1st article 

5y/100 = (40x - C.P₁)/(C.P₁)

⇒ 0.05y + 1 = 40x/C.P₁

⇒ C.P1 = (40x)/(0.05y + 1)      ----(ii)

For 2nd article 

4y/100 = (37x - C.P2)/(C.P2)

⇒ 0.04y + 1 = 37x/C.P2

⇒ C.P2 = (37x)/(0.04y + 1)      ----(iii)

According to the question 

C.P1 = C.P2 

⇒ (40x)/(0.05y + 1) = (37x)/(0.04y + 1)

⇒ 1.6xy + 40x = 1.85xy + 37x

⇒ y = 12   ----(iv)

Form (i) and (iv), we get 

x = 19.2

So, Sum of cost price = 2 × [(40x)/(0.05y + 1)] + 480

⇒ 2 × 480 + 480

∴ The required sum is Rs. 1440.

Calculation:

Let the savings of 1st and 2nd person be 23x and 28x respectively

We know that, Expenditure = Salary - Saving 

Expenditure of 1st person = 12000 - 23x 

Expenditure of 2nd person = 12000 - 28x

So, According to the question 

$\frac {12000 \ - \ 23x}{12000 \ - \ 28x} = \frac {5}{4}$

⇒ 48000 - 92x = 60000 - 140x

⇒ 48x = 12000

⇒ x = 250

So, The expenditure of 2nd person = 12000 - 28x

⇒ 12000 - 28 × 250

⇒ 12000 - 7000 = 5000

∴ The expenditure of 2nd person is Rs. 5000.

 

Alternate Method 

Given: 

The salary of two persons is the same = Rs. 12000

The ratio of expenditure of 1^st and 2^nd person = 5 : 4

The ratio of the savings = 23 : 28

Formula used:

Salary = Expenditure + Saving 

Calculation: 

Let the expenditure of both persons be 5x and 4x respectively

Let the Saving be 23y and 28y 

According to the formula used

5x + 23y = 12000             ----(1) 

4x + 28y = 12000             ----(2) 

Multiply eq (1) by 4 and eq (2) by 5, we get

20x + 92y = 48000           ---(3)

20y + 140y = 60000         ---(4)

On subtracting equation (3) from (4), we get

⇒ 48y = 12000

⇒ y = Rs. 250

Put the value of y in equation (2), we get

4x + 28 × 250 = 12000 

⇒ 4x = 12000 - 7000 = Rs 5000 

∴ The correct answer is Rs 5000.

Given 

The ratio of first two numbers = 6 : 17

The ratio of 3rd and 4th = 27 : 59

Calculation 

Let the required number be x 

Now, According to the question 

(6 + x)/(17 + x) = (27 + x)/(59 + x)

⇒ (6 + x) (59 + x) = (27 + x) (17 + x)

⇒ 354 + 65x + x² = 459 + 44x + x²

⇒ 21x = 105 

⇒ x = 5 

∴ The correct answer is option 1.

Given: 

Length of train = 225 m 

Length of platform = 275 m 

Speed of train = 36 km/hr

Formula Used:

Time = Distance/Speed 

x km/hr = (x × 5/18) m/s 

Calculation: 

Speed of train = 36 km/hr

⇒ 36 × 5/18 = 10 m/s 

Total distance travelled by train = (Train + Platform) length

Totatl distance = 225 m + 275 m = 500 m

S0, Time taken by train to cross platform = 500/10

⇒ 50 sec.

∴ The correct answer is option 2.

Given 

Speed of swimmer in still water = 5 km/hr

Speed increased by 10% at the time of diving for the first 30 m.

Total distance of the journey = 50 + 50 = 100 m

Formula Used 

x km/hr = x × 5/18 m/s 

Time = Distance/Speed 

Calculation 

Speed of swimmer for the first 30 m = 5 + 10% of 5

⇒ 5.5 km/hr 

5 km/hr = 5 × 5/18 = (25/18) m/s 

5.5 km/hr = 5.5 × 5/18 = (27.5/18) m/s 

Time taken to cover first 30 m = (30)/(27.5 ÷ 18) 

⇒ 30 × 18/27.5 = 19.63 sec

Time taken to cover 70 m = 70/(25 ÷ 18) 

⇒ 70 × 18/25 = 50.4 sec

Total time = 50.4 + 19.63 = 70.03 second 

∴ The correct answer is option 3.

Given

Two person A and B are at a distance = 100m

Formula Used 

Speed = Distance/Time 

Calculation 

When B covers 20 m so A also cover 20 m 

Now distance b/w them = 100 - 40 = 60 m 

Now B turns left and move 10 m but A moves straight 10 m 

Now B turns right and moves 10 m but A moves straight 10 m 

So, Distance b/w them = 60 - 10 - 20 = 30 m 

Now B turns right and moves 10 m towards the same path of A and A also cover 10 m straight 

So, Remaining Distance b/w them = 30 - 10 = 20 m 

∴ The correct answer is option 2.

Given:

A boat takes 1 hr 30 min to cover a certain distance in upstream

The boat takes 1 hr time to cover the same distance in downstream

Speed of boat in still water = 7.5 km/hr 

Formula Used:

Speed of upstream = speed of the boat in still water - speed of the stream 

Speed of downstream = speed of the boat in still water + speed of the stream 

Calculation: 

Let the speed of stream be x 

According to the question

Distance travelled in upstream = Distance travelled in downstram

(7.5 - x) × 1.5 = (7.5 + x) × 1

⇒ 7.5 × 1.5 - 1.5x = 7.5 + x

⇒ 7.5 × 1.5 - 7.5 = x + 1.5x

⇒ 7.5 (1.5 - 1) = 2.5x

⇒ x = 3.75/2.5 = 1.5 km/hr 

∴ The correct answer is option 4.

Given 

Speed of boy along 1st edge = 2 m/s 

Speed of boy along 2nd edge = 3 m/s 

Speed of boy along 3rd edge = 4 m/s 

Speed of boy along 4th edge = 6 m/s 

Formula used 

Average Speed = Total Distance/Total time 

Time = Distance/Speed 

Calculation 

LCM of (2, 3, 4, 6) = 12 

Let length of each edge of square field be 12

Average speed = (12 × 4)/[(12/2) + (12/3) + (12/4) + (12/6)] 

⇒ 48/(6 + 4 + 3 + 2) = 16/5 m/s = $3\frac{1}{5} \ m/s$

∴ The correct answer is option 1.

Given:

Time taken by A = 12 days

Time taken by B = 16 days

Time taken by C = 24 days

B and C worked together = 4 days

Formula used:

Work = Efficiency × Time

Calculation:

LCM of 12, 16 and 24 is 48

Efficiency of A = (48/12) = 4 units/day

Efficiency of B = (48/16) = 3 units/day

Efficiency of C = (48/24) = 2 units/day

Time taken by B and C together for 4 days = [4 × (3 + 2)]

⇒ (4 × 5) = 20 units

The remaining work = (48 – 20) = 28 units

Now,

Time taken by B and A to complete the remaining work = [28/(3 + 4)]

⇒ 28/7 days

⇒ 4 days

∴ The required time is 4 days

Given 

A man can do work = 4 days 

A woman can do work = 12 days 

A boy can do work = 60 days 

Formula Used 

Work = Efficiency × Time 

Calculation 

LCM of (4, 12 and 60) = 60 

Let total work be 60 unit

Efficiency of Man = 60/4 = 15 unit/day

Efficiency of Woman = 60/12 = 5 unit/day

Efficiency of Boy = 60/60 = 1 unit/day

Work done by 2 Men and 5 Women in 1 day = 2 × 15 + 5 × 5

⇒ 55 units

Remaining work = 5 units 

Since, One day work of 1 boy = 1 unit 

One day work on 5 boys = 5 units

So, the required number of boys os 5.  

∴ The correct answer is option 4.

Given 

Original Number of Soldier = 200

Number of Soldier after 27 days = 200 - 120 = 80 

Formula Used 

(M₁ × D₁ × E₁)/W₁ = (M₂ × D₂ × E₂)/W₂

Calculation 

Let the required number of days be D

According to the question 

The remaining food was for 200 soldiers for 4 days 

And this food will be consumed by the remaining 80 soldiers 

So, According to the formula used

200 × 4 = 80 × D

⇒ D = 10 days 

∴ The correct answer is 10 days.

Given

Average time = 2 minutes 10 second

number of athletes = 7

Formula used

Average = Sum of all observation/Number of observation

1 minute = 60 seconds

Calculation

Total time taken by 7 athletes = 7 × (2 minutes and 10 seconds)

⇒ 7 × 130 seconds

⇒ 910 seconds

⇒ 15 minutes 10 seconds

Average time taken by other athletes = (15 minutes 10 seconds - 1 minute 40 seconds)/6

⇒ (13 minutes 30 seconds)/6

⇒ 2 minutes 15 seconds 

since (13 minutes = 12 minutes + 1 minute)

⇒ 12 minutes are divided by 6 = 2 minutes

⇒ 1minutes = 60 seconds

⇒ total 60 + 30 seconds

⇒ 90 seconds 

when 90 is divided by 6 = 15 

so, average time is 2 minutes 15 seconds

∴ Average time is 2 minutes 15 seconds

Shortcut Trick Given:-

Average time of all 7 players (a) = 2 min 10 sec = 130 sec

Average time of n players (b) = 1 min 40 sec = 100 sec

Average of remaining players(c) = ?

Formula used :-

Number of remaining player = $\large{\frac{n(a -b)}{(c -a)}}$ 

Calculation:-

According to question-

⇒ 6 = [1 × (130 - 100)]/(c - 130)

⇒ 6c - 780 = 30

⇒ 6c = 810

⇒ c = 135 = 2 min 15 sec

∴ Average time of remaining players is 2 min 15 sec.

Given:

An inlet pipe takes 8 hrs to fill the tank 

An outlet pipe takes 6 hrs to drain the tank

Formula Used:

Total capacity of tank (Work) = Efficiency × Time 

Calculation:

Let the number of inlet pipes be x 

So, the number of outlet pipes = (8 - x)

Capacity of tank = LCM of (8, 6) = 24 litres

Efficiency of an inlet pipe = 24/8 = 3 litres/hr

Efficiency of x inlet pipe = 3x litres/hr

Efficiency of an outlet pipe = 24/6 = -4 litres/hr

Efficiency of (8 - x) outlet pipe = -4(8 - x) litres/hr

According to the question in 6 hours tank will be empty 

So, (3x × 6) + [-4(8 - x) × 6] = -24      

⇒ 18x - 192 + 24x = -24   

⇒ 42x = 168 

⇒ x = 4

∴ The total number of inlet pipes are 4.

Given:

An article is marked above the cost price = 50%

The profit earned by the shopkeeper = 8%

Two successive discounts are 10% and 20%

Formula Used: 

Total discount = - d1 - d2 + (d1d2/100)

Selling Price = Cost Price(1 + Profit%/100)

Marked Price = Cost Price (1 + Marked%/100)

Calculation: 

Let the cost price of an article be 100x 

Marked Price of an article = 100x + 50% of 100x = 150x 

Total discount = -10 - 20 + (10 × 20)/100 

⇒ -28%

⇒ Selling Price of an article = 150x - 28% of 150

⇒ 108x 

⇒ Profit = 108x - 100x = 8x 

Now, 8x = 8 

⇒ x = 1

So, The cost price of the article = 100 × 1

⇒ Rs 100

∴ The correct answer is Rs. 100.
