1. Only three stores sold less books than U

2. S sold more books than R and P but less than U

3. P sold more books than R

    >   > U > S > P > R

4. T did not sell the highest number of books

Q > T > U > S > P > R

It is given that the store which sold the second-highest number of books sold 72 books. From above it is clear that store T sold the second-highest number of books. So, store Q sold the highest number of books.

By option, we can say store Q sold 89 books because 72 is the second highest.

1. Only three stores sold less books than U

2. S sold more books than R and P but less than U

3. P sold more books than R

    >   > U > S > P > R

4. T did not sell the highest number of books

Q > T > U > S > P > R

 Hence, P sold the second lowest number of books.

1. Only three stores sold less books than U

2. S sold more books than R and P but less than U

3. P sold more books than R

    >   > U > S > P > R

4. T did not sell the highest number of books

Q > T > U > S > P > R

Given; P + T = 125, and T = 72

P + 72 = 125

P = 125 - 72 = 53

Hence, store P sold 53 books.

The least possible Venn diagram is:

Conclusions:

I. Some Sweet are not Bitter → True (As, Only a few Sweet are Bitter is given which means Some Sweet are Bitter and Some Sweet are not Bitter).

II. Some Tasty are Bitter → True (As, Only a few Bitter are Tasty is given, which means Some Bitter are Tasty and Some Bitter are not Tasty, which also shows that Some Tasty are Bitter).

III. All Apple being Sweet is a possibility  → True (The possibility is true, as shown below).

Hence, All Conclusion follows.

The least possible Venn diagram is:

Conclusions:

I. Some Deserts being Winter is a possibility → False (As, Only Cold is Winter is given which means All Winter are Cold and Winter will not have any positive relationship with any element except with Cold, so Some Deserts being Winter is definitely false conclusion and possibility with definite conclusion is false).

II. Some Cold being Desert is a possibility → True (The possibility is true, as no direct relationship between the two is given).

III. All Warm being Cold is possibility → False (As, Only a few Warm are Cold is given, which means Some Warm are Cold and Some Warm are not Cold, so All Warm being part of Cold is definitely false conclusion and possibility with definite conclusion is false).

Hence, Only Conclusion II follows.

The least possible Venn diagram is:

Conclusions:

I. Some Clips are not Rubber → True (As, Only Hair band is Rubber is given which means All Rubber are Hair band and Rubber will not have any positive relationship with any other element except with Hairband, so Some Clips are not Rubber is True).

II. Some Rubber are not Eyeliner → True (Only Hair band is Rubber is given which means All Rubber are Hair band and Rubber will not have any positive relationship with any other element except with Hairband, and No Hairband is Eyeliner is given, so Some Rubber are not Eyeliner is true).

III. All Eyeliner being Hair band is a possibility → False (As, Hair band and Eyeliner both have relationship of No with each other, so the possibility is false).

Hence, Both Conclusion I and II follows.

The least possible Venn diagram is:

Conclusions:

I. All Red being Blue is a possibility → True (The possibility is true, as Only a few Blue are Red is given, which means Some Blue are Red and Some Blue are not Red, which also states that Some Red is Blue, but we don't know about the remaining portion of Red whether it is Blue or not, so this is possible).

II. Some Black is Blue → False (This is possible but not definite).

III. Some Pen which is Blue is not Red → False (This is possible but not definite).

Hence, Only Conclusion I follows.

Males are now being urged to calm down due to growing concerns that high-pressure living, fascinating though it may appear, is a silent killer and one of the reasons men have a lower life expectancy than women. Ironically, though, more and more career-driven women are swiftly picking up on some of the same "killing" behaviours, which explains why they have traditionally outlasted men in terms of "longevity" metrics.

Option II puts forth additional information, which may or may not be true. This renders it unsound as an assumption behind the passage.

Option IV again, though carries possibly relevant information, cannot be safely selected as an assumption.

Option III would be far- fetched one whereas option I which gives the clear assumption behind the passage.

So, option I is the right option.

According to the assertion, for-profit universities enroll a higher percentage of financially disadvantaged students than non-profit institutions. This conclusion is supported by the fact that a disproportionate amount of federal and state financial help is received by students attending for-profit universities. The claim makes an assumption that there is a correlation between the percentage of help received and the number of financially disadvantaged students enrolled. In doing so, it makes the assumption that the distribution of aid is disproportionate for no other reason.

A. Public vs. private non-profit institutions are different, but these distinctions are unimportant to the discussion.

B. This is the best option. A possible explanation for the unequal distribution of aid is that for-profit institutions used dishonest methods to secure superfluous financial help for their students. By claiming that this was not the case, this response option disproves the alternative explanation and draws attention to a crucial premise that underlies the assertion.

C. The actual proportion of students receiving financial help at for-profit as opposed to non-profit universities has no bearing on the claim.

D. The debate, which is entirely focused on variations in financial assistance distribution, does not address the relative educational quality of for-profit vs. non-profit universities.

E. It doesn't matter if students are successful in repaying their debts after graduation because the claim is still valid.

So, option B is the answer.

Nowadays, medicine cannot always cure us, but it can lessen the effectiveness of our symptoms and improve our condition. Traditional medicine is called Traditional for a Reason. It is old fashioned and outdated. It is not as effective as Modern Medicine. Some traditional treatments work well but modern medicine just takes these traditional treatments and makes them more effective. Modern medicine can have side effects, but if taken with regulation and not in overdose, modern medicine can be the most effective way to help yourself.

I. instead of comparing modern medicine with traditional medicine, it just talks about traditional medicine. So, this does not weaken the statement.

II. Instead of comparing modern medicine with traditional medicine it only talks of lawsuits against modern medicine manufacturers. Also, it is a lawsuit but side effects of modern medicines are not proved. So, this is not related.

III. This weakens the statement because it says that most modern medicines have harmful side effects whereas traditional medicines don’t.

IV. Profit does not mean modern medicine is not better than traditional medicine. So, this does not weaken the argument.

Hence, option III is the correct answer.

Let's have a look at all immediate courses of action given:

I - This course of action should immediately be followed as this rescue operation will help the flood victims.

II - This course of action should immediately be followed because food is an essential requirement for human beings for their survival and flood victims are unable to get it.

III - This course of action should is not appropriate to be immediately followed as money is not an immediate requirement of the flood victims.

Hence, the correct answer will be only (II) and (I).

Given:

People who like Pepsi in a society = Percentage (%) of total people in that society

Calculation:

Let the number of people who like Pepsi in societies A, B, C, D and E be a, b, c, d and e respectively.

Then, Number of people who like Pepsi in society A = 25% of total people

⇒ a = (25/100) × (a + 1,800 + 1,500)

⇒ 4a = a + 3,300

⇒ a = 1,100

Number of people who like Pepsi in society B = 30% of total people

⇒ b = (30/100) × (b + 2,000 + 800)

⇒ 10b = 3b + 8,400

⇒ b = 1,200

Number of people who like Pepsi in society C = 20% of total people

⇒ c = (20/100) × (c + 1,750 + 1,050)

⇒ 5c = c + 2,800

⇒ c = 700

Number of people who like Pepsi in society D = 45% of total people

⇒ d = (45/100) × (d + 2,200 + 1,100)

⇒ 20d = 9d + 29,700

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

Now, the total number of people who like Mirinda in all the societies together = 1,800 + 2,000 + 1,750 + 2,200 + 2,400

⇒ 10,150

and the total number of people who like Thums Up in all the societies together = 1,500 + 800 + 1,050 + 1,100 + 900

⇒ 5,350

Required difference = 10,150 - 5,350

⇒ 4,800

∴ The difference between the total number of people who like Mirinda in all the societies together and the total number of people who like Thums Up in all the societies together is 4,800.

Given:

People who like Pepsi in a society = Percentage (%) of total people in that society

Calculation:

Let the number of people who like Pepsi in societies A, B, C, D and E be a, b, c, d and e respectively.

⇒ a = 1,100

Number of people who like Pepsi in society B = 30% of total people

⇒ b = (30/100) × (b + 2,000 + 800)

⇒ 10b = 3b + 8,400

⇒ b = 1,200

Number of people who like Pepsi in society C = 20% of total people

⇒ c = (20/100) × (c + 1,750 + 1,050)

⇒ 5c = c + 2,800

⇒ c = 700

Number of people who like Pepsi in society D = 45% of total people

⇒ d = (45/100) × (d + 2,200 + 1,100)

⇒ 20d = 9d + 29,700

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

Total number of people who like Pepsi in the societies A, B and C together = 1,100 + 1,200 + 700

⇒ 3,000

and the total number of people who like Thums Up in the societies D and E together = 1,100 + 900

⇒ 2,000

Now, required ratio = 2,000 ∶ 3,000

⇒ 2 ∶ 3

∴ The ratio of the total number of people who like Thums Up in the societies D and E together to the total number of people who like Pepsi in the societies A, B and C together is 2 ∶ 3.

Given:

People who like Pepsi in a society = Percentage (%) of total people in that society

Formula used:

Average = (Sum of values)/(Number of values)

Calculation:

Let the number of people who like Pepsi in societies A, B, C, D and E be a, b, c, d and e respectively.

Then, Number of people who like Pepsi in society A = 25% of total people

⇒ b = 1,200

Number of people who like Pepsi in society C = 20% of total people

⇒ c = (20/100) × (c + 1,750 + 1,050)

⇒ 5c = c + 2,800

⇒ c = 700

Number of people who like Pepsi in society D = 45% of total people

⇒ d = (45/100) × (d + 2,200 + 1,100)

⇒ 20d = 9d + 29,700

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

Total number of people in society A = 1,100 + 1,800 + 1,500 = 4,400

Total number of people in society B = 1,200 + 2,000 + 800 = 4,000

Total number of people in society C = 700 + 1,750 + 1,050 = 3,500

Total number of people in society D = 2,700 + 2,200 + 1,100 = 6,000

and the total number of people in society E = 2,200 + 2,400 + 900 = 5,500

Now, total number of people in all the societies together = 4,400 + 4,000 + 3,500 + 6,000 + 5,500

⇒ 23,400

Required average = 23,400/5

⇒ 4,680

∴ The average number of people in all the societies together is 4,680.

Given:

People who like Pepsi in a society = Percentage (%) of total people in that society

Formula used:

Percentage = (Favourable value/Base value) × 100

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

Total number of people who like Pepsi in the societies A and B together = 1,100 + 1,200 = 2,300

and the total number of people who like Mirinda in the societies D and E together = 2,200 + 2,400 = 4,600

Now, required percent = (2,300/4,600) × 100

⇒ a = (25/100) × (a + 1,800 + 1,500)

⇒ 4a = a + 3,300

⇒ a = 1,100

Number of people who like Pepsi in society B = 30% of total people

⇒ b = (30/100) × (b + 2,000 + 800)

⇒ 10b = 3b + 8,400

⇒ b = 1,200

Number of people who like Pepsi in society C = 20% of total people

⇒ c = (20/100) × (c + 1,750 + 1,050)

⇒ 5c = c + 2,800

⇒ c = 700

Number of people who like Pepsi in society D = 45% of total people

⇒ d = (45/100) × (d + 2,200 + 1,100)

⇒ 20d = 9d + 29,700

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

Total number of people in society B = 1,200 + 2,000 + 800 = 4,000

and the total number of people in society D = 2,700 + 2,200 + 1,100 = 6,000

Now, required difference = 6,000 – 4,000 = 2,000

Required percent = (2,000/4,000) × 100

⇒ 50%

∴ The total number of people in society D is 50% more of the total number of people in society B.

Given:

People who like Pepsi in a society = Percentage (%) of total people in that society

Formula used:

Percentage = (Favourable value/Base value) × 100

Calculation:

Let the number of people who like Pepsi in societies A, B, C, D and E be a, b, c, d and e respectively.

Then, Number of people who like Pepsi in society A = 25% of total people

⇒ a = (25/100) × (a + 1,800 + 1,500)

⇒ 4a = a + 3,300

⇒ a = 1,100

Number of people who like Pepsi in society B = 30% of total people

⇒ b = (30/100) × (b + 2,000 + 800)

⇒ 10b = 3b + 8,400

⇒ b = 1,200

Number of people who like Pepsi in society C = 20% of total people

⇒ c = (20/100) × (c + 1,750 + 1,050)

⇒ 5c = c + 2,800

⇒ c = 700

Number of people who like Pepsi in society D = 45% of total people

⇒ d = (45/100) × (d + 2,200 + 1,100)

⇒ 20d = 9d + 29,700

⇒ d = 2,700

and number of people who like Pepsi in society E = 40% of total people

⇒ e = (40/100) × (e + 2,400 + 900)

⇒ 5e = 2e + 6,600

⇒ e = 2,200

So, the following table will be prepared:

The total number of people who like Pepsi in all the societies together = 1100 + 1200 + 700 + 2700 + 2200 

⇒ 7900

Given :

Marked price of article 'P' = 1260 Rs.

Discount given on article 'P' = 25%

Profit made on article 'P' = 5%

Overall profit made on both articles = 37.5%

Average selling price of both articles = 1443.75 Rs.

Calculation :

Selling price of article 'P' = 1260 × 75% = 945 Rs.

Cost price of article 'P' = 945/1.05 = 900 Rs.

Total selling price of both articles = 1443.75 × 2 = 2887.5 Rs.

Total cost price of both articles = 2887.5/1.375 = 2100 Rs.

Cost price of article 'Q' = 2100 - 900 = 1200 Rs.

Selling price of article 'Q' = 2887.5 - 945 =1942.5 Rs.

Profit% earned on article 'Q' = [(1942.5 - 1200)/1200] × 100 = 61.875%

Hence, the correct answer is 61.875%.

Speed of Vande Bharat express is 9 unit and speed of Tejas express train is 13 unit.

 Relative speed is when they going in the same direction = 13 unit - 9 unit = 4 unit.

 And relative speed is the same every moment it means speed is constant then the Time ratio is equal to the distance ratio.

 When Tejas express overtakes and crossed Vande Bharat express they travel distance, which is equal to the length of Tejas and the length of Vande Bharat.

 Distance = T + V 

 They take 185 seconds to overtake 

 When Sachin observe the Vande Bharat express then this distance is equal to length of Vande Bharat express. 

 Distance = V

 They take 90 seconds to cross 

 Time ratio is  185 : 90 ⇒ 37 : 18

 When speed is constant then the time ratio is equal to the distance ratio 

 Then  T+V : V = 37 : 18

    ⇒ T + V = 37 

    ⇒ T + 18 = 37

    ⇒ T = 37 -18 = 19

 The ratio of length of Train Vande Bharat and Tejas express is 18 : 19 respectively.

 Hence, 18 : 19 is the correct answer.

Given:

Ratio of Investment made by Anand, Binod and Chanchal in March = 3 ∶ 2 ∶ 5

Calculation:

39000 ∶ (2x - 8000) ∶ (3x + 14000) = 3 ∶ 2 ∶ 5

⇒ 39000/(2x - 8000) = 3/2

⇒ 2 × 39000 = 3 × (2x - 8000)

⇒ 78000 = 6x - 24000

⇒ 6x = 102000

⇒ x = 17000

Calculation:

Let the profit of Anand in January be x and in February be y.

Investment of Anand in January ∶ Investment of Binod in January = Profit of Anand in January ∶ Profit of Binod in January

⇒ 32000 ∶ 34000 = x ∶ 17000

⇒ 16 ∶ 17 = x ∶ 17000

⇒ x = 16000

∴ Profit of Anand in January = Rs. 16000

Investment of Anand in February ∶ Investment of Chanchal in February = Profit of Anand in February ∶ Profit of Chanchal in February

⇒ 39000 ∶ 60000 = y ∶ 12000

⇒ 13 ∶ 20 = y ∶ 12000

⇒ y = 7800

∴ Profit of Anand in February = Rs. 7800

∴ Required ratio = 16000 ∶ 7800

⇒ Required ratio = 80 ∶ 39

Given:

Ratio of Investment made by Anand, Binod and Chanchal in March = 3 ∶ 2 ∶ 5

Calculation:

39000 ∶ (2x - 8000) ∶ (3x + 14000) = 3 ∶ 2 ∶ 5

⇒ 39000/(2x - 8000) = 3/2

⇒ 2 × 39000 = 3 × (2x - 8000)

⇒ 78000 = 6x - 24000

⇒ 6x = 102000

⇒ x = 17000

Investment of Anand and Binod together = Rs. 41000

Investment of Chanchal = Rs. 20000

Anand invested for 10 days

Binod invested for 15 days

Anand's profit = Rs. 5000

Binod's profit = Rs. 13000

Chanchal's profit = Rs. 12000

Concept Used:

Ratio of investment corresponding to time = Ratio of their respective profits

Calculation:

Let the investment of Anand be x and investment of Binod be y.

Let Chanchal invested his amount for 'n' days.

(x × 10) ∶ (y × 15) ∶ (20000 × n) = 5000 ∶ 13000 ∶ 12000

⇒ 2x ∶ 3y ∶ 4000n = 5 ∶ 13 ∶ 12

⇒ 2x ∶ 3y = 5 ∶ 13

⇒ x ∶ y = 15 ∶ 26

∵ x + y = 41000

∴ x = (15/41) × 41000

⇒ x = 15000

y = 41000 - 15000

⇒ y = 26000

3y ∶ 4000n = 13 ∶ 12

⇒ (3 × 26000) ∶ 4000n = 13 ∶ 12

⇒ 39 ∶ 2n = 13 ∶ 12

⇒ 39/2n = 13/12

⇒ n = (39 × 12)/(2 × 13)

⇒ n = 18

∴ Chanchal invested his amount of Rs. 20000 for 18 days.

From statement I:

Let speed of Avi be x m/sec and Sia be b m/sec

Distance travel by sia in 10sec = b/10

Difference between distance travel by Avi and Sia is 100 meters. 

this statement is not sufficient to answer the question. 

From statement II:

Avi takes 100 sec to finish the race. 

Speed of Avi to finish 500 m race = 500/100 = 5 m/sec

Time taken by Sia to complete the race 110 sec.

Speed of Sia to complete the 500m race = 400/110 = 3.63 m/sec 

Hence statement II is sufficient to answer the question.

let the total work = 60 units

efficiency of P+Q+S = 60/12 = 5

Statement I: P and Q together can complete the work in 15 days.

efficiency of P+Q = 60/15 = 4

efficiency of S = 5-4 = 1

S starts working alone for the first 6 days and then, left the work.

Total work completed by S alone = 6*1 = 6 units

Remaining work = (60-6)/R = 54/R

So, the data in statement I alone is not sufficient to answer the question.

Statement II: R and S together can complete the work in 10 days.

efficiency of R+S = 60/10 = 6

So, the data in statement II alone is not sufficient to answer the question.

Combining both statements I and II together: If S = 1

Then, the efficiency of R = 6-1=5

time taken by R to complete the remaining work = 54/5 = 10.8 days

Hence, the correct answer is the data in both statements I and II together are necessary to answer the question.

Statement I: Mr. Yash invested Rs. ‘P’ in a scheme offering R% p.a. Simple interest and Interest earned by him after 4 years is Rs.1600.

Therefore, (P×R×4)/100 = 1600

Or, P×R = 40000 ...(a)

Here we have two variables, so the equation can't be solved.

So, statement I alone is not sufficient to answer the question.

Statement II: Mr. Yash invested Rs. ‘P’ in a scheme offering R% p.a. Simple interest and Interest earned by him after 5 years is Rs.2000.

Therefore, (P×R×5)/100 = 2000

Or, P×R = 40000 ...(b)

Here we have two variables, so the equation can't be solved.

So, statement II alone is not sufficient to answer the question.

Combining statement (I) and (II): we notice that both the equations (a) and (b) are identical. Therefore, the value of P and R can't be determined.

The correct is the data given in both statements I and II together are not sufficient to answer the question.

Given:

From statement I,

The total marks obtained by Raj in Hindi, Mathematics and Physics = 270 

The total marks obtained by Raj in Hindi and Mathematics = 195

From statement II,

The ratio between the marks obtained by Raj in Hindi and Physics = 6 : 5

Calculation:

From statement I and II together,

Marks in Physics = (Total marks in Hindi, Mathematics and Physics) - (Total marks in Hindi and Mathematics)

⇒ 270 - 195

⇒ 75

Let the marks obtained by Raj in Hindi and Physics be 6x and 5x respectively.

Then, 5x = 75

⇒ x = 15

Marks in Hindi = 6 × 15

⇒ 90

Marks in Mathematics = 195 - (Marks in Hindi)

⇒ 195 - 90

⇒ 105

Required ratio = 105/75

⇒ 7/5

⇒ 7 : 5

Hence the ratio between the marks obtained by Raj in mathematics and physics = 7 : 5

∴ Both statement I and statement II together is needed to answer the question.

Statement I:

Given:

Added quantity of water = 12 l

Ratio of alcohol and water after addition of water = 8 : 3

Calculation:

Let x be the initial quantity of water

Equating the quantity of water

{(x + 12)/(120 + 12)} = 3/(8 + 3)

⇒ (x + 12)/132 = 3/11

⇒ (x + 12)/12 = 3

⇒ x + 12 = 36

⇒ x = 36 – 12 = 24

Quantity of water in 120 liters mixture is 24 l

Quantity of alcohol in 120 liters mixture is 120 – 24 = 96 l

∴ Statement I alone is sufficient to answer the question.

Statement II:

Given:

Quantity of mixture replaced with alcohol = 20 l

The ratio of alcohol and water after replacement = 5 : 1

Calculation:

Let the quantity of alcohol be x

⇒ Quantity of alcohol after replacement = (x/120) × 100 = 5x/6

⇒ Quantity of water after replacement = 100 – (5x/6)

Equating with given ratio

{(5x/6) + 20}/{100 – (5x/6)} = 5/1

⇒ {(5x/6) + 20} = 500 – (25x/6)

⇒ (30x/6) = 480

⇒ x = 480/5 = 96

Quantity of alcohol in 120 liters mixture is 120 – 24 = 96 l

The quantity of water in 120 liters mixture is 24 l

∴ Statement II alone is sufficient to answer the question.

∴ Either statement I alone or statement II alone is sufficient to answer the question.

Given:

CP of Redmi Note 10 pro = Rs. 18000

Concept used:

Profit% = Profit = {(SP - CP)CP} × 100

Calculation:

MP = 18000 × 13/10

⇒ Rs. 23400

According to the question,

Price after discount = 23400 × 85/100

⇒ Rs. 19890

SP = Rs 19890

Given:

CP of Redmi Note 10 pro = Rs. 18000

Concept used:

Profit% = Profit = {(SP - CP)CP} × 100

Calculation:

MP = 18000 × 13/10

⇒ Rs. 23400

According to the question,

Price after discount = 23400 × 17/20

⇒ Rs. 19890

SP = 19890 – 1000

⇒ Rs.18890

Profit % = {(18890 – 18000)/18000} × 100

⇒ 89/18

⇒ 4.944%≈ 4.9% 

∴ The profit percentage of the Mi store is 4.9%

Given:

CP of Redmi Note 10 pro = Rs. 18000

CP of Poco M3 = Rs. 24999

Concept used:

Profit = {(SP - CP)CP} × 100

Calculation:

MP of Poco M3 = Rs. 18000 × 200%

⇒ 36000

According to the question,

36000 – x = 24999 + x

⇒ 2x = 11001

⇒ x = 5500.5

⇒ Profit = Rs. 5500.5

Profit % = 5500.5/24999 × 100

⇒ 22.0028% ≈ 22%

∴ Profit percentage on selling is 22%

Given:

Marked up % = 20%

Discount % = 15%

Concept used:

Profit/loss = + MP% – Discount% + {(MP% × Discount%)/100}

Calculation:

As we know about successive increase or decrease

• 20% – 15% + {20 × (-15)}100

⇒ + 5% - 3%

⇒ + 2%

∴ Required profit % is 2%

Given:

CP of Mi 10 lite NE = 25000

Concept used:

MP = CP × Marked up %

Calculation:

Marked price of Redmi Note 10 pro = 18000 × 13/10

⇒ 23400

Marked price of Mi 10 lite NE = 25000 × 6/5 × 4/3

⇒ 30000 × 4/3

⇒ 40000

Ratio = 23400 : 40000

⇒ 117 : 200

∴ Required ratio between marked price of Redmi Note 10 pro and marked price of Mi 10 lite NE is 117 : 200

Given:

MP = Rs. 26666

Profit = 20%

Discount = 10%

Concept used:

SP = CP × profit %

SP = MP × Discount %

Calculation:

According to the question,

CP = 26666 × 9/10 × 5/6

⇒ 26666 × 3/4

⇒ 19999..5 

⇒ CP = Rs. 20000

∴ The cost price Redmi Note 10 pro Max is Rs. 20000

The area of the path = (22/7) * (21² – 14²)

= > (22/7) * (21 + 14) (21 – 14)

= > (22/7) * 35 * 7 

= > 770 sq m

Hence the area of the path is 770 sq m.

Perimeter of circle = 2 * (22/7) * r = 1320 / 10 

r = 132 * (7/22) * (1/2) = 21 m

Perimeter of equilateral triangle = 3a = 540 / 12 = > a = 45 / 3 = 15 m 

Perimeter of equilateral triangle = 3a = 540 / 12 = > a = 45 / 3 = 15 m 

Perimeter of square = 768 / 8 = 96 = > 4a = 96 = > a = 24 m

Perimeter of rectangle = 500 / 5 = 100 = > 2 * (l + b) = 100 

= > l + b = 50 m 

Area of rectangle = 576 sq m

= > lb = 576

= > l * (50 – l) = 576

= > 50l – l² = 576

= > l² – 50l + 576 = 0

= > (l - 32) (l - 18) = 0

= > l = 32, 18

If l = 32,

then b = 18

If l = 18,

then b = 32

The length of the rectangle is always greater than the breadth.

So, l = 32 m, b = 18 m

The length of the rectangle (l) = 32 m

Hence the length of the rectangle is 32 m.

In an election survey 83(1/3) % total voters took part in survey 

⇒ 83(1/3) % = 250 / 300 = 5 / 6

It means the total number of voters is 6 units and the voters, who participated in the survey is 5 units 

For easy calculation we let 6 unit = 180 and 5 unit = 150 

Total number of people, who participated in the survey is 150

50% of people, who participated in the survey voted for candidate D

⇒ 150 × 50% = 75

10% are uncertain 

 ⇒ 150 × 10% = 15

Rest people voted for candidate E

⇒ 150 - (75 + 15) 

⇒ 150 - 90 = 60

Those who do not participate in the survey they voted for D and E in a ratio 2 :1 respectively.

People who do not participate in the survey are 180 - 150 = 30

Then, the vote of 30 people divided in a ratio 2 : 1

⇒ 3 units = 30

⇒ 1 unit = 10

Vote for Candidate D = 20

Vote for Candidate E = 10

Uncertain number of people are 15 

They voted for D and E in a ratio 1 : 4 respectively

⇒ 5 units = 15

⇒ 1 unit = 3

Vote for Candidate D is 3

Vote for Candidate E is 4 units = 4 × 3 = 12

Total votes received by D is (75 + 20 + 3) = 98

Total votes received by E is (60 + 10 + 12) = 82

Here D win by 98 - 82 unit = 16 units 

16 units = 640

1 unit = 40

So, the total number of voters in the election is 180 × 40 = 7200

Hence, 7200 is the correct answer.

Given:

Black balls + Yellow balls = 9

Probability of selecting two red balls = 1/7 = Probability of selecting two black balls 

Concept used:

A combination is the choice of r things from a set of n things without replacement and where order does not matter and is given by 

⇒  ⁿC_r = n!/{r! × (n - r)!}

Probability of an event = number of favourable outcomes/total possible outcomes

Calculation:

Let the number of red and black balls be x and y respectively

Then, probability of selecting two red balls = (^xC₂)/(^{(9 + x)}C₂) = 1/7

⇒ x × (x - 1)/(9 + x)(8 + x) = 1/7

⇒ 7x² - 7x = x² + 17x + 72

⇒ 6x² - 24x - 72 = 0 

⇒ x = 6 

∴ Number of red balls = 6

Total number of balls  = 9 + 6 = 15

Now, the probability of selecting two black balls from the bag = (^yC₂)/(¹⁵C₂) = (1/7) × 100/250

⇒ y(y - 1)/(15 × 14) = (1/7) × (2/5)

⇒ y = 4

∴ The number of black ball = 4

∴ The number of yellow coloured ball = 15 - 6 - 4 = 5 balls.

Given:

Number of students who like only Brown color =  25% less than the number of students who like only White color

Number of students who like Blue color but not White color = 2 ×  Number of students who like only Brown color

Number of students who like only like only Blue color = (5/4) × Number of students who like both Brown and Blue colors but not White color

Sum of number of students who like both White and Brown colors and both White and Blue colors is 1,500

Number of students who like both White and Brown colors but not Blue color : Number of students who like both White and Blue colors but not Brown color is 3 : 1

Number of students who like all the three colors = (1/4) × Number of students who like both Brown and Blue colors but not White color

Calculation: 

Number of students who like only Brown color =  25% less than the number of students who like only White color.

⇒ [(100 – 25)/100] × 1,200

⇒ (75/100) × 1,200

⇒ 900

Number of students who like Blue color but not White = 2 × 900

⇒ 1,800

Let the number of students who like both Brown and Blue colors but not White color be 4x.

Then, the number of students who like only Blue color = (5/4) × 4x = 5x

So, 5x + 4x = 1,800

⇒ 9x = 1,800

⇒ x = 200

Number of students who like both Brown and Blue colors but not White color = 4 × 200 = 800

and the number of students who like only Blue color = 5 × 200 = 1,000

Number of students who like all the three colors = (1/4) × 800

⇒ 200

Let the number of students who like both White and Brown colors but not Blue color and the number of students who like both White and Blue colors but not Brown color be 3y and y respectively.

Then, (3y + 200) + (y + 200) = 1,500

⇒ 4y + 400 = 1,500

⇒ 4y = 1,100

⇒ y = 275

Number of students who like both White and Brown colors but not Blue color = 3 × 275 = 825

Now, the following venn diagram will be prepared:

Total number of students who like Brown color = 825 + 200 + 800 + 900

⇒ 2,725

So, the number of girls who like Brown color = (48/100) × 2,725

⇒ 1,308

∴ The number of girls who like Brown color is 1,308.

Given:

Number of students who like only Brown color =  25% less than the number of students who like only White color

Number of students who like Blue color but not White color = 2 ×  Number of students who like only Brown color

Number of students who like only like only Blue color = (5/4) × Number of students who like both Brown and Blue colors but not White color

Sum of number of students who like both White and Brown colors and both White and Blue colors is 1,500

Number of students who like both White and Brown colors but not Blue color : Number of students who like both White and Blue colors but not Brown color is 3 : 1

Number of students who like all the three colors = (1/4) × Number of students who like both Brown and Blue colors but not White color

Calculation: 

Number of students who like only Brown color =  25% less than the number of students who like only White color.

⇒ [(100 – 25)/100] × 1,200

⇒ (75/100) × 1,200

⇒ 900

Number of students who like Blue color but not White = 2 × 900

⇒ 1,800

Let the number of students who like both Brown and Blue colors but not White color be 4x.

Then, the number of students who like only Blue color = (5/4) × 4x = 5x

So, 5x + 4x = 1,800

⇒ 9x = 1,800

⇒ x = 200

Number of students who like both Brown and Blue colors but not White color = 4 × 200 = 800

and the number of students who like only Blue color = 5 × 200 = 1,000

Number of students who like all the three colors = (1/4) × 800

⇒ 200

Let the number of students who like both White and Brown colors but not Blue color and the number of students who like both White and Blue colors but not Brown color be 3y and y respectively.

Then, (3y + 200) + (y + 200) = 1,500

⇒ 4y + 400 = 1,500

⇒ 4y = 1,100

⇒ y = 275

Number of students who like both White and Brown colors but not Blue color = 3 × 275 = 825

Now, the following venn diagram will be prepared:

Total number of students who like only one color = 1,200 + 900 + 1,000

⇒ 3,100 students

and the total number of people who like only 2 colors = 275 + 825 + 800

⇒ 1,900 students

So, required difference = 3,100 – 1,900

⇒ 1,200

∴ The difference between the total number of students who like only one color and the total number of students who like only two colors is 1,200.

Given:

Number of students who like only Brown color =  25% less than the number of students who like only White color

Number of students who like Blue color but not White color = 2 ×  Number of students who like only Brown color

Number of students who like only like only Blue color = (5/4) × Number of students who like both Brown and Blue colors but not White color

Sum of number of students who like both White and Brown colors and both White and Blue colors is 1,500

Number of students who like both White and Brown colors but not Blue color : Number of students who like both White and Blue colors but not Brown color is 3 : 1

Number of students who like all the three colors = (1/4) × Number of students who like both Brown and Blue colors but not White color

Formula used:

Percentage = (Favourable value/Base value) × 100

Calculation: 

Number of students who like only Brown color =  25% less than the number of students who like only White color.

⇒ [(100 – 25)/100] × 1,200

⇒ (75/100) × 1,200

⇒ 900

Number of students who like Blue color but not White = 2 × 900

⇒ 1,800

Let the number of students who like both Brown and Blue colors but not White color be 4x.

Then, the number of students who like only Blue color = (5/4) × 4x = 5x

So, 5x + 4x = 1,800

⇒ 9x = 1,800

⇒ x = 200

Number of students who like both Brown and Blue colors but not White color = 4 × 200 = 800

and the number of students who like only Blue color = 5 × 200 = 1,000

Number of students who like all the three colors = (1/4) × 800

⇒ 200

Let the number of students who like both White and Brown colors but not Blue color and the number of students who like both White and Blue colors but not Brown color be 3y and y respectively.

⇒ 4y + 400 = 1,500

⇒ 4y = 1,100

⇒ y = 275

Number of students who like both White and Brown colors but not Blue color = 3 × 275 = 825

Now, the following venn diagram will be prepared:

Required percent = (825/1,200) × 100

⇒ 68.75%

∴ The number of students who like both White and Brown colors but not Blue color is 68.75% of the number of students who like only White color.

So, 5x + 4x = 1,800

⇒ 9x = 1,800

⇒ x = 200

Number of students who like both Brown and Blue colors but not White color = 4 × 200 = 800

and the number of students who like only Blue color = 5 × 200 = 1,000

Number of students who like all the three colors = (1/4) × 800

⇒ 200

Let the number of students who like both White and Brown colors but not Blue color and the number of students who like both White and Blue colors but not Brown color be 3y and y respectively.

Then, (3y + 200) + (y + 200) = 1,500

⇒ 4y + 400 = 1,500

⇒ 4y = 1,100

⇒ y = 275

Number of students who like both White and Brown colors but not Blue color = 3 × 275 = 825

Now, the following venn diagram will be prepared:

The total number of students in the school = 1,200 + 825 + 900 + 275 + 200 + 800 + 1,000

⇒ 5,200 students.

∴ The total number of students in the school is 5,200.
