The correct answer is I only.

Key Points

• The relationship between the quantity of a commodity chosen by a consumer and the price of that commodity is called the demand curve.
• Demand curve is a graphic presentation of various quantities of a commodity that a consumer is willing to buy at different prices of the same commodity, while holding constant prices of other related commodities and income of the consumer.
• The downward sloping demand curve shows that at lower prices, the individual is willing to buy more of commodity.
• However at higher prices, the indivdual is willing to buy less of commodity x.
• Therefore, there is a negative relationship between price of a commodity and quantity demanded which is referred to as the Law of Demand.
• The law of diminishing marginal utility states that each successive unit of a commodity provides lower marginal utility.
• If a consumer's demand for a good moves in the same direction as the consumer's income, the consumer's demand for that good must be inversely related to the price of the good.
• It is called Law of demand.
• The law of demand is a fundamental principle in macroeconomics. It is used together with the law of supply to determine the efficient allocation of resources in an economy and find the optimal price and quantity of goods.
• The law of demand states that other factors being constant (cetris peribus), price and quantity demand of any good and service are inversely related to each other. When the price of a product increases, the demand for the same product will fall.

r → 10 : 13

V → 10³ : 13³ = 1000 : 2197

Increment in volume = (2197 - 1000)/1000 × 100%

⇒ 1197/1000 × 100% = 1197/10% = 119.7%

 

So, the volume of sphere will increase 119.7%.

Given:

P = Rs 2400 

T = 2 years

SI = Rs. 288 

Formula Used:

SI = PRT/100

Calculation:

SI = PRT/100

⇒ 288 = 2400 × R% × 2/100 

⇒ 288 = 2400 × R% × 2/100

⇒ R% = 288/*(24 × 2) = 6%

So, Annual rate of interest is 6%.

r²Given:

Radius of cylinder(R) = 2 × radius of cone(r)

Height of cylinder(H) = 5 × height of cone(h)

Formula Used:

Volume of cylinder = n × volume of cone

πR²H = n × 1/3πr²h

Calculation:

We know that,

πR2H = n × 1/3πr2h

According to question,

R = 2r

H = 5h

π × (2r)² × 5h = n × 1/3πr²h

n = 3 × (π × 4r² × 5h)/(πr²h)

⇒ 3 × 4 × 5 = 60

Given:

M is 25% more than N.

Concept Used:

If A is R% more than b,

Then B is [R/(100 + R) × 100]% less than A less than A.

Calculation:

N = [R/(100 + R) × 100]% 

⇒ [25/(100 + 25) × 100]% 

⇒ [25/125  × 100]% 

⇒ 1/5  × 100]%  = 20%

\(\therefore \mathbf{ N ;is ;20%; less ;than; M}.\)

Given:

 

• J1 = Average Selling Price (P, Q, R, S),
• J2 = The total difference between the price of the quantity and the selling price of all the 7 articles.

Formula Used:

Average = sum of all observation/total number of observations

Calculation:

J1 = (P + Q + R + S)/4 = (500 + 200 + 500 + 600)/4 = 1800/4 = 450

J2 = The total difference between the price of the quantity and the selling price of all the 7 articles

⇒ 100 + 200 + 300 + 400 + 200 + 300 + 100 = 1600

J2 - J1 = 1600 - 450 = 1150

 

So, the value of J2 - J1 = 1150.

Given:

• The number of car C1 sold by P is 160 percent of the number of cars C1 sold by Q.
• The average number of cars C3, C4 and C5 sold by R is 65.
• The sum of the number of all cars sold by Q is 380.

Formula Used:

Average = sum of all observations/total number of observations

Calculation:

1)The number of car C1 sold by P is 160 percent of the number of cars C1 sold by Q

Number of cars C1 sold by P = 40

Number of cars C1 sold by Q = 25

% of C1 cars sold by P with respect to Q = 40/25 × 100 = 160

So, case 1 is absolutely correct.

2)The average number of cars C3, C4 and C5 sold by R is 65

Average = sum of all observations/total number of observations

⇒ (C3 + C4 + C5)/3 = (45 + 70 + 80)/3 = 195/3 = 65

So, case 2 is also absolutely correct.

3. ​The sum of the number of all cars sold by Q is 380

The sum of the numbers of all cars sold by Q = 25 + 15 + 60 + 120 + 160 = 380​

So, case 3 is also correct.

Hence, all three cases are correct.

Given:

Diameter of cycle wheel = 4.2 cm

Speed = 23.1 kmph

Time = 90 minutes

Formula Used:

Speed = distance/Time

Circumference of circle = 2πr

Number of rounds = total distance covered by wheel/distance covered in a single round

Calculation:

Total distance covered by wheel = speed × time

⇒ 23.1 × 90/60 = 23.1 × 1.5 = 34.65 km

Distance covered in a single round = 2πr = 2 × 22/7 × 2.1

⇒ 13.2

Number of rounds = Total distance covered by wheel/distance covered in a single round = (34.65 × 1000 × 100 cm)/13.2 cm

⇒ 262500

So, 262500 revolutions will the wheel make during the journey.

Given:

Initial Profit = 20%

Reduce in CP and SP = Rs 20 

Final Profit = 30%

Formula Used:

Profit% = profit/CP × 100

Calculation:

Let Initial CP = Rs. x

Initial SP = x × 120/100 = Rs. 6x/5

Initial Profit = 6x/5 - x = x/5

Final CP = Rs (x - 20)

Final SP = 6x/5 - 20

Final profit = x/5 

Final Profit % = (x/5)/(x - 20) × 100%

⇒ 30% = x/5(x - 20) × 100%

⇒ 30 = x/(x - 20) × 20

⇒ 3/2 = x/(x - 20)

⇒ 3x - 60 = 2x

x = 60

So, Initial Cast Price is  Rs. 60

Given:

a = \(\sqrt {6 - \sqrt {11 } } \) 

b = \(\sqrt {6 +\sqrt {11 } } \) 

Formula Used:

(a - b)² = a² + b² - 2ab

Calculation:

a² = 6 - √11

b² = 6 + √11

⇒ 2ab = 2 × √(6 -√11) × √(6 + √11) = 2 × √(36 - 11) = 2 × √25 = 2 × 5 = 10

⇒ (b - a)2 = a2 + b2 - 2ab = 6 + √11 + 6 - √11 - 10 = 12 - 10 = 2

(b - a) = √2

So, \(√2\) is the correct answer.

Given:

Speed of bike = 39.6 kmph

Distance = 330 m =0.33 km

Formula Used:

Speed = distance/ time

Calculation:

Time = distance/ speed = 0.33/39.6 hours = 33/3960 hours = 1/120 hours = 1/120 × 60 × 60 seconds = 30 sec

∴ The bike take 30 sec to cover a distance of 330 metres.

Given:

\(\frac{6}{{5 + 4√ 3 }}\)

Solution:

\(\frac{6}{{5 + 4√ 3 }}\) = 6/(5 + 4√3) × (5 - 4√3)/(5 - 4√3) 

⇒ 6(5 - 4√3)/(25 - 16 × 3) = (30 - 24√3)/-23 = (24√3 - 30)/23

∴ \(\frac{6}{{5 + 4√ 3 }}\) = (24√3 - 30)/23

Given:

(24 ÷ 8 × 5) – (8 × 3 ÷ 2)

Concept Used:

We have to follow the BODMAS rule→

Calculation:

(24 ÷ 8 × 5) – (8 × 3 ÷ 2)

⇒ (3 × 5) - (8 × 3/2)

⇒ 15 - (4 × 3) = 15 - 12 = 3

So, (24 ÷ 8 × 5) – (8 × 3 ÷ 2) = 3 is correct answer.

Given:

Investment of Amar = 10000 Rs. for 2 months

Investment of Ritesh = 24000 Rs. for 6 months

Investment of Karan = 16000 Rs. for 8 months

Formula Used:

If any amount M is divided in a:b:c then,

I part = M × a/(a + b + c)

II part = M × b/(a + b + c)

III part = M × c/(a + b + c)

Calculation:

Ratio of share of Amar, Ritesh and Karan 

⇒ 10000 × 2 : 24000 × 6 : 16000 × 8

⇒ 10 : 12 × 6 : 8 × 8

⇒ 5 : 36 : 32

∴Combined share of Aman and Karan = 146000 × (32 + 5)/73 = 2000 × 37 = 74000

Shortcut Trick

If each number in a given set is multiplied by a certain constant, the new average is simply the old average multiplied by the same constant.

New Average = Old Average × Constant

New Average = 22 × 3 = 66

∴ The correct answer is 66.

Alternate Method

Given:

Average of 13 numbers = 22

Constant multiplier for each number = 3

Formula Used:

Average = Sum of all observations ÷ Total number of observations

Property of Averages

Original Average:

22

Each number × 3

New Average:

66 (i.e. 22 × 3)

Calculations:

⇒ Sum of the original 13 numbers = Average × Total numbers

⇒ Original Sum = 22 × 13 = 286

⇒ When each individual number is multiplied by 3, the total sum is also multiplied by 3.

⇒ New Sum = Original Sum × 3

⇒ New Sum = 286 × 3 = 858

⇒ New Average = New Sum ÷ Total numbers

⇒ New Average = 858 ÷ 13 = 66

∴ The correct answer is 66.

Additional Information

Addition and Subtraction Property

If a constant value 'k' is added to or subtracted from each observation in a dataset, the new average becomes (Old Average + k) or (Old Average − k).

Multiplication and Division Property

If each observation is multiplied or divided by a non-zero constant 'k', the new average becomes (Old Average × k) or (Old Average ÷ k).

Combined Average

If group 1 has n₁ items with average A₁ and group 2 has n₂ items with average A₂, the Combined Average = (n₁A₁ + n₂A₂) ÷ (n₁ + n₂).

Given:

P + Q can complete a work in 10 days 

Q + R can complete same work in 15 days

P + Q + R can complete it in 7.5 days

Formula Used:

If A finish a work in D days then 

per day work of A = 1/D

Calculation:

Per day work of P + Q = 1/10

Per day work of Q + R = 1/15

Per day work of P + Q + R = 2/15

Per day work of P = (P + Q + R) - (Q + R) = 2/15 - 1/15 = 1/15

Per day work of R = (P + Q + R) - (P + Q) = 2/15 - 1/10 = (4 -3)/30 = 1/30

Per day work of P + R = 1/15 + 1/30 = 230 + /30 = 1/10

So, P and R can complete the same work in 10 days.

Given:

Given number is 5872Y.

Concept Used:

Key Points

• In the first part of the sentence, let's identify the subject.
• "Goods, services and skills" are not the subject here whereas, "The accelerated flow" is the subject, which is singular.
• Hence, 'is' the singular of the Present Tense of the verb 'be' is qualified to be used with this subject**.**

Thus, the error part of the sentence is option (4) part 1, i.e., "The accelerated flow of goods, services and skills are."

Key Points

• In the subject of the sentence 'Either' and 'or' have been used as determiner.
• The determiner indicates that only one of two persons, either Vimla or Kamla processes the cake.
• Hence, it has to be treated as singular subject.
• As the tense used is Present Indefinite, the verb(1^st) + s/es needs to be used.
• In all the options, option (4) 'bakes' only qualifies with the mentioned condition.

Thus, the appropriate word to be filled in the blank is option (4) 'bakes' and the sentence: -

Either Vimla or Kamla bakes the cake.

The correct answer is "To bribe".

Key Points

• Here, the idiom given in the question means “to bribe, to pay off corruptly."
• For example: “If you want to get out of the jail, grease warden's palm and the guards will let you escape.”

• Sorrow: Grief, sadness for a loss, affection, this word is some relevant with the situation but not qualified one.
• Awful: Bad, unpleasant, dreadful, terrible, word which is both relevant and qualified for the given situation.

Thus, the appropriate word for the blank space is 'Awful'.

• The para opens with a short description of songs. Which is "Songs are the most faithful of friends".
• The next part needs to be telling us more about friends and relate with the opening sentence, which is “Our friends may change over time.”
• The next sentence i.e. “but our songs are always patiently waiting to talk to us” completes the preceding part.
• The next sentence continues to explain songs as they are friends, "They are never cross, peevish, or unwilling to converse".

• with good grace- Gratefully, cordially, cheerfully

The correct answer is option (1) “PRSQ”

 Key Points

• The opening part contains adjective large which refers to next part "Square Mahogany box".
• The next part "Well polished and there was a" is in logical sequence as it mentions the condition of the box.
• The previous part ended up with 'there was a' which has to be followed by living/non-living object rather than a preposition. This object is the handle in 'Handle you have to wind'.
• Further, It will be followed by the only remaining part of the sentence.

Therefore, the correct order of the parts of sentence after rearrangement would be PRSQ: -

“It was a large square mahogany box, well-polished and there was a handle you have to wind to open the lids at the top.”

The correct answer is 'dislike for her has been increasing'.

 

Key Points

• The correct phrase should be 'dislike for her has been increasing' to indicate an ongoing increase in his dislike.

Therefore, the correct answer is- 'Option 2'.

 

Additional Information

• Option 1 'dislike with her has being increasing' is incorrect due to inappropriate preposition 'with' and incorrect usage of 'being'.
• Option 3 'No improvement' is not applicable as an improvement is needed in the given sentence.
• Option 4 'dislike to her has been increasing' is incorrect due its improper usage of preposition 'to'.
