From Figure (4) to Answer Figure:

The triangle and rectangle interchange their positions and two lines are added.

Hence, the correct answer is "Option (1)".

The logic followed here is:

Logic: (First number × 9) - 7 = Second number

• 21, 182 → (21 × 9) - 7 = 189 - 7 = 182
• 14, 119 → (14 × 9) - 7 = 126 - 7 = 119

Similarly,

• 17, 146 → (17 × 9) - 7 = 153 - 7 = 146

Hence, '17, 146' is the correct answer.

P + Q × R - S ÷ T → P is mother of Q, Q is husband of R, R is sister of S, S is daughter of T.

By using the symbols in the table given below, we can draw the following family tree:

Clearly, Q is T's daughter's husband.

Hence, ‘Daughter's husband’ is the correct answer.

Given equation: 42 × 7 ÷ 13 - 87 + 12 = ?

If '+' and '-' are interchanged and '×' and '÷' are interchanged, then the equation becomes:

42 ÷ 7 × 13 + 87 - 12 = ?

⇒ 6 × 13 + 87 - 12 = ?

⇒ 78 + 87 - 12 = ?

⇒ 165 - 12 = ?

⇒ 153 = ? 

Hence, ‘153’ is the correct answer.

The logic followed here is:

Hence, '88' is the correct answer.

An ordinary year has 1 odd day and a leap year has 2 odd days. 

So, the day on the same date for an ordinary year will be 1 day ahead and the day on the same date for a leap year will be 2 days ahead for the next year.

Sheela celebrated her birthday on Wednesday, 10 April 2019.

Days on these dates will be:

10 April 2020 → Friday

10 April 2021 → Saturday

10 April 2022 → Sunday 

10 April 2023 → Monday

Clearly, it will be Monday on her birthday in 2023.

Hence, ‘Monday’ is the correct answer.

The logic followed here is:

Hence, '43' is the correct answer.

The logic followed here is:

Hence, 'LDQZ' is the correct answer.

The number of triangles in the given figure is shown below:

Hence, '6' is the correct answer.

The correct mirror image of the given figure when the mirror is placed at MN is shown below:

Hence, 'option 1' is the correct answer.

The least possible Venn diagram is:

Conclusions: 

(I) Some Yarns are Sheets. → Follows (As, Some Sheets are Drapes and All Drapes are Yarns which means some yarns are sheets)

(II) Some Sheets are Curtains. → Does not follow (As, there is no definite relation between parrots and birds. Hence, false)

Hence, 'Only conclusion (I) follows' is the correct answer.

P ÷ Q × R + S - T → P is wife of Q, Q is father of R, R is brother of S, S is mother of T

By using the symbols in the table given below, we can draw the following family tree:

P is maternal grandmother of T, i.e., P is T's mother's mother.

Hence, ‘Mother's Mother’ is the correct answer.

The least possible Venn diagram is:

Conclusions:

(I) Some classes are nails. → Does not follow (As, No nail is a classes, so Some classes are not nails)

(II) All tools are classes. → Does not follow (As, All classes are tools, so some tools are classes)

(III) Some nails are tools. → Follows (As, Some tools are nails, so Some nails are tools)

Hence, 'Only conclusion III follows' is the correct answer.

The logic followed here is:

Logic: First number - 107 = Second number

1. 444 ∶ 339 → 444 - 107 = 337 ≠ 339
2. 189 ∶ 82 → 189 - 107 = 82
3. 401 ∶ 294 → 401 - 107 = 294
4. 500 ∶ 393 → 500 - 107 = 393

Hence, '444 ∶ 339' is the correct answer.

The logic followed here is:

Hence, 'AYG' is the correct answer.

The code for each letter is shown below:

Here, the alphabet 'AINED' is common in both the word,

So, the remaining alphabet 'T' will be coded as the remaining number '9',

And, the remaining alphabet 'P' will be coded as the remaining number '3',

Clearly, '9' is the code for 'T' in the given code language.

Hence, '9' is the correct answer.

42 A 7 B 13 C 87 D 12 = ?

After replacing the letters by their meaning, we get:

42 ÷ 7 × 13 + 87 - 12 = ?

⇒ 6 × 13 + 87 - 12 = ?

⇒ 78 + 87 - 12 = ?

⇒ 165 - 12 = ?

⇒ 153 = ?

Hence, ‘153’ is the correct answer.

An ordinary year has 1 odd day and a leap year has 2 odd days. 

So, the day on the same date for an ordinary year will be 1 day ahead and the day on the same date for a leap year will be 2 days ahead for the next year.

If 11 August 1918 is Sunday, then the day on these dates will be:

11 August 1919 → Monday

11 August 1920 → Wednesday

11 August 1921 → Thursday

11 August 1922 → Friday

11 August 1923 → Saturday

11 August 1924 → Monday

11 August 1925 → Tuesday

Number of days between 11 August 1925 to 4 December 1925 = (20 + 30 + 31 + 30 + 4) = 115

115 when divided by 7, leaves 3 as remainder.

Tuesday + 3 = Friday

Therefore, it will be Friday on 4 December 1925.

Hence, ‘Friday’ is the correct answer.

Alternate MethodGiven: 11 August 1918 is Sunday.

So, 11 August 1918 to 11 August 1925 = 7 Years (5 Ordinary and 2 leap Year)

In 7 years = (5 × 1) + (2 × 2) = 5 + 4 = 9 days.

And, from 11 August 1925 to 4 December 1925 = 20(Aug) + 30(Sept) + 31(Oct) + 30(Nov) + 4(Dec) = 115 days

Total days = 9 + 115 = 124 days → 124/7 = 17 week and 5 odd days.

So, 4 December 1925 = Sunday + 5 + Friday.

Hence. the correct answer is "Option 4".

The logic followed here is:

Hence, 'BGW' is the correct answer.

The logic followed here is:

Logic: (First number × 3) - 1 = Second number

1. 72 ∶ 215 → (72 × 3) - 1 = 216 - 1 = 215
2. 99 ∶ 296 → (99 × 3) - 1 = 297 - 1 = 296
3. 86 ∶ 252 → (86 × 3) - 1 = 258 - 1 = 257 ≠ 252
4. 115 ∶ 344 → (115 × 3) - 1 = 345 - 1 = 344

Hence, '86 ∶ 252' is the correct answer.

The logic followed here is:

Hence, '383' is the correct answer.

• They have also played together in doubles tournaments, but they did not win the title in Bangkok Open 2023.
• Divij Sharan:-
• He is another Indian tennis player who has won several doubles titles in his career, but he did not win the Men's Double title in Bangkok Open 2023.

The correct answer is low information monitoring costs.

Key Points

• Lack of access to credit for the poor:-
• It is a pervasive problem in many developing countries, and it can be attributed to various factors.
• One of the main reasons is the lack of a stable source of income, which makes it difficult for lenders to assess the creditworthiness of the borrower and increases the risk of default.
• Another reason is the absence of collateral with clear title, which makes it difficult for lenders to secure their loans and reduces their willingness to lend to poor borrowers.
• Lenders may also prefer dealing in large loans in small numbers to minimize administration costs, which can make it difficult for poor borrowers who need small loans to access credit.
• However, low information monitoring costs are not a reason for the lack of access to credit for the poor. In fact, low monitoring costs can make it easier for lenders to monitor the use of the loan and reduce the risk of default.

The correct answer is 1932.

Key Points

• Carl Anderson:-
• He was an American physicist who won the Nobel Prize in Physics in 1936 for his discovery of the positron.
• Anderson's discovery also led to the development of positron emission tomography (PET), which is now widely used in medical imaging.

Additional Information

• Positron:-
• It is the antiparticle of an electron and has the same mass as that of an electron but carries a positive charge.
• The discovery of the positron provided evidence for the existence of antimatter, which was predicted by Paul Dirac in 1928.

The correct answer is Both A and B.

 Key Points

• Capital receipt:-
• It refers to the inflow of funds that are not generated from the regular operations of a business or organization.
• It can include sources such as sale of assets, borrowing, or capital contributions from shareholders or investors.
• Borrowings from World Bank to fund Project to Save Tigers - This is a capital receipt because it increases a liability (the amount borrowed needs to be repaid) and is intended for a capital project (funding a specific conservation project).
• Sale of 30% stake in a PSU to private companies is an example of capital receipt, as it is an inflow of funds from the sale of an asset.

The correct answer is Financial services could enable the poor to earn high rates of interest on deposits.

Key Points

• Micro-finance:-
• It refers to providing financial services to low-income individuals or groups who lack access to traditional banking services.
• It is aimed at enabling them to start or expand their small businesses, build assets, and improve their economic security.
• However, earning high rates of interest on deposits is not a key feature of micro-finance, as it is primarily focused on providing credit and savings services rather than investment opportunities.
• Micro-finance has been widely adopted as a development strategy to alleviate poverty and promote economic growth in many developing countries.

Given

A sphere is melted and moulded into a solid cylinder.

Formula Used:

volume of sphere = 4/3 × 22/7 × r³; 

Total surface area of sphere = 4 × 22/7 × r²; where r = radius of sphere 

Volume of cylinder = 22/7 × R² × h

Total surface area of cylinder = 2 × 22/7 × R(R + h); where R = radius of cylinder, h = height of cylinder

Calculation:

Let the number of cylinder formed be n.

Since the sphere is melted into a cylinder i.e. volume remains the same

⇒ 4/3 × 22/7 × 9³ = n × 22/7 × 3² × 2

⇒ n = 54 

The answer is 54.

Given:

 Δ ABC ~ ΔPQR

Concept used:

AAA (Angle-Angle-Angle) congruency rule: The two triangles are said to be congruent if any angles included between the sides of one triangle are equivalent to the corresponding angles between the sides of another triangle.

Calculations:

As we know,

The triangles is similar to each other,

Then the corresponding angles will also be equal.

∠A = ∠P, 

                ∠B = ∠Q and ∠C = ∠R

∠B = 180 - (80 + 10) = 90

∠B = ∠Q = 90º

The answer is 90º

Formula used

if a + b + c = 0, then a³ + b³ + c³ = 3abc

Calculation

$\frac{(1-m)^3+(m-n)^3+(n-1)^3}{12(1-m)(m-n)(n-1)}=$

$\frac{(1-m)^3+(m-n)^3+(n-1)^3}{4 \times 3(1-m)(m-n)(n-1)}=$

Since 1 - m + m - n + n - 1 = 0, 

⇒ $\frac{(1-m)^3+(m-n)^3+(n-1)^3}{4 \times 3(1-m)(m-n)(n-1)}$

⇒ $\frac{3(1-m)(m-n)(n-1)}{4 \times 3(1-m)(m-n)(n-1)}$

⇒ 1/4

The answer is 1/4.

Calculation

The monthly profit of P = 800

The monthly profit of U = 320

The ratio = 800: 320 = 5:2

The answer is 5:2

Given:

Payment per delivery: ₹90

Average daily earnings for 15 days: ₹540

Average earnings for the first 7 days: ₹519

Average earnings for the last 7 days: ₹546

Total working days: 15.

Formula used:

Average = sum of observation/total number of observation.

Calculations:

Total earnings for 15 days ⇒ ₹540 × 15 = ₹8100.

Total earnings for the first 7 days ⇒ ₹519 × 7 = ₹3633.

Total earnings for the last 7 days ⇒ ₹546 × 7 = ₹3822.

Adding earnings of the first 7 days and last 7 days ⇒ ₹3633 + ₹3822 = ₹7455.

Subtracting this total from the overall total earnings for 15 days to find the 8th day's earnings: ₹8100 - ₹7455 = ₹645.

Hence, Rajender's earning on the 8th day of the fortnight was ₹645.

Given:

x2 + y2 + z2 = 628

xy + yz + zx = 24

Formula used:

(x + y + z)² = x2 + y2 + z2 + 2(xy + yz + zx)

Calculations:

(x + y + z)2 = x2 + y2 + z2 + 2(xy + yz + zx)

(x + y + z)2 = 628 + 2×24) = 628 + 48 = 676

((x + y + z)² = 676) ⇒ (x + y + z ) = 26

Hence, the value of ((x + y + z)) is 26

Calculation:

The number of Meteorology =  17% 

The number of  Astrophysics = 23%

⇒ (17/23)× 100 =73.91%

Hence, the correct option is (4).

Calculation:

⇒ $\frac{2secA}{sec^2 -1}$ = $\frac{2secA}{tan^2A}$ [sec²A - tan²A = 1]

⇒ (2 × cos²A) / (cosA × sin²A) [secA = 1/cosA, tanA = (sinA / cosA)]

⇒ 2 cosecA cotA [cosecA = 1/sinA, cotA = (cosA / sinA]

∴ The correct answer is 2 cosecA cotA.

Given : 

The speed of a boat in standing water = 9 km/h

The speed of the stream =1.5 km/h.

Distance = 105 km

Formula used :

Speed = Distance / Time

Concept used :

Now when the boat goes down the boat flows along with the water hence speed of the boat will be increased by the speed of the current.

Downstream speed = speed of still water + speed of the stream

Now when the boat goes down the boat flows against the water hence speed of the boat will be decreased by the speed of the current.

Upstream speed = speed of still water -  speed of the stream

Calculation : 

Downstream speed = 9 + 1.5 = 10.5 km/h

Upstream speed = 9 - 1.5 = 7.5 km/h

Total time = (105/10.5) + (105/7.5)

Total time = 10 + 14 hours = 24 hours

Hence, the correct option is (1).

Given: 

Principal (P) = ₹12,000

First-year interest rate (r1) = 5%

Second-year interest rate (r2) = 10% 

Calculation:

A1 = P(1 + r1)

A1 = 12000(1 + 0.05)

A1 = 12000 × 1.05 = ₹12,600

Second Year: For the second year, we use the amount at the end of the first year as the principal.

P2 = A1 (the amount from the first year becomes the principal for the second year)

A2 = P2(1 + r2)

A2 = 12600(1 + 0.1)

A2 = 12600 × 1.1 = ₹13,860

Compound Interest = A2 - P

Compound Interest = 13860 - 12000 = ₹1,860

Therefore, the compound interest Kalyan earned at the end of two years is ₹1,860.

Shortcut Trick

5% = 1/20

10 = 1/10

Amount after 2 year = 12000 × 21/20 × 11/10 = 13860

 Interest = 13860 - 12000 =  ₹1,860

Formula used:

SI = PRT/100

Calculation:

Let the Amount invested at 12% be Rs. 100x

And the Amount invested at 10% be Rs. 100y

⇒ 130 = (100x × 12 × 1)/100 + (100y × 10 × 1)/100

⇒ 12x + 10y = 130     ----(i)

Now, according to the question,

Amount invested at 12% = Rs. 100y

Amount invested at 10% = Rs. 100x

⇒ 134 = (100y × 12 × 1)/100 + (100x × 10 × 1)/100

⇒ 12y + 10x = 134      ----(ii)

On solving (i) and (ii), we get

⇒ 10(12x + 10y) = 10(130)

⇒ 12(10x + 12y) = 12(134)

⇒ 120x + 100y = 1300

⇒ 120x + 144y = 1608

Subtract the second equation from the first:

⇒ 120x + 100y - (120x + 144y) = 1300 - 1608

⇒ 120x + 100y - 120x - 144y = -308

⇒ -44y = -308

⇒ y = 7

Substitute the value of (y) into one of the original equations to find (x). 

⇒ 12x + 10(7) = 130

⇒ 12x + 70 = 130

⇒ 12x = 60

⇒ x = 5

Therefore, (100x = 500) and (100y = 700).

∴ Amount invested at 12% simple interest = Rs. 500

Calculation :

Let the amount that Sunaina has = A

And the amount that Ranjan has = B

Then according to the question,

The sum of the amount = 23 

⇒ A + B = 23         -------(1)

And the difference of the amount = 7

⇒ A - B = 7           --------(2)

On solving equation(1) and equation(2)

A = 15 and B = 8

Now, A : B = 15 : 8

∴ The ratio of the amount that Sunaina and Ranjan have is 15 : 8.

Given:

The marked price of the article is 40% above the cost price

Discount of 7.5% on UPI payments

Concept Used:

Marked price (MP) = 100 × SP/(100 - d)

Where SP = Selling price, and d = discount percentage

Calculation:

Selling Price of the shirt = Rs. 1813

According to the formula,

Marked price (MP) of the shirt

⇒ 100 × 1813 / (100 - 7.5) = Rs. 1960

Now the MP of the shirt is 40% more than the cost price (CP)

So, CP = 100 × 1960 / (100 + 40) = Rs. 1400

Profit earned = (1813 - 1400) = Rs. 413

∴ Actual profit made on the shirt is Rs. 413

Given:

Marked price = Rs 560

Discount = 16%

Profit = 12%

Formula used:

MP / CP = [(100 + P%) /(100 - D%)]

%P = [(SP - CP) / CP] × 100

MP = marked price, CP = cost price, D =discount, P = profit, SP = selling price

Calculation:

⇒ 560 / CP = (112/84)

⇒ CP = (560 × 84) /112 = 420

If no discount on MP then MP will be SP

⇒ P = SP - CP = 560 - 420 = 140

⇒ %P = (140/420) × 100 = 33$\frac{1}{3}$%

∴ The correct answer is  33$\frac{1}{3}$%.

Given

Radius = 8 cm

Concept used

The radius is perpendicular to the Rchord and divides it into two equal halves.

Calculation

According to the question:

Let PQ divide RS at O.

RO = √(82 - 42)

RO = √48 = 4√3

RS = 2 × RO

RS = 2 × 4√3 = 8√3

The answer is 8√3 cm

Calculation

87 × 256 + 16 - 77 ÷ 1359

After changing the signs:

⇒ 87 + 256 ÷ 16 × 77 - 1359

⇒ 87 + 16 × 77 - 1359

⇒ 87 + 1232 - 1359

⇒ 1319 - 1359 = - 40

The answer is - 40.

Average = 423/30 = 14.1 years

The answer is 14.1 years

Given:

Two circles having a radius 40 cm and 30 cm

Length of transverse tangent = 10√15 cm

Formula used:

AB= √[(Distance between the centers of two circles)² - (Sum of radius)²]

Where, AB = length of transverse tangent

Calculation:

Let, (Distance between the centers of two circles = oo'

By using the formula,

10√15 = √[(oo')² - (40 + 30)²]

⇒ 10√15 = √[(oo')2 - (70)2]

On squaring both sides,

⇒ (10√15)² = (oo')2 - (70)2

⇒ 1500 = (oo')2 - 4900

⇒ 1500 + 4900= (oo')2 

⇒ 6400= (oo')2 

⇒ oo' = 80 cm

∴ The correct answer is 80 cm.

Formula used

Cos² A = 1 - Sin² A

Calculation

$\frac{\cos ^2 A}{(1+\sin A)}$

⇒ (1 - Sin2 A)/(1 + SinA)

⇒ (1 - SinA)(1 + SinA)/(1 + SinA)

⇒ 1 - SinA

The answer is 1 - SinA

Given:

$x+\frac{1}{x}=-1$

Calculation:

⇒ $x+\frac{1}{x}=-1$

Multiplying both sides by x we get,

⇒ x² + 1 = -x

⇒ x2 + x + 1 = 0

Multiplying both sides by (x - 1) we get,

⇒ (x - 1)(x2 + x + 1) = 0

⇒ x³ + x² + x - x2 -x -1 = 0

⇒ x3 -1 = 0

⇒ x3 = 1   ---- eq (1)

Now,  $x^{15}+\frac{1}{x^{15}}$ = $(x^{3})^5+\frac{1}{(x^{3})^5}$

Putting x³ = 1 from eq (1) we get,

⇒ 1⁵ + (1/1⁵) = 1 + 1 = 2

∴ The correct answer is Option 2).

Given:

Initial ratio of two numbers: 1 ∶ 2

After adding 7 to both numbers, new ratio: 3 ∶ 5

Solution:

⇒ Let the smaller number be (x) and the larger be (2x) (according to the initial ratio 1 ∶ 2).

⇒ After adding 7 to both, the numbers change to (x + 7) and (2x + 7) respectively.

⇒ The new ratio is given to be 3 ∶ 5, thus $\frac{x + 7}{2x + 7} = \frac{3}{5}$

⇒  5(x + 7) = 3(2x + 7)

⇒ (5x + 35 = 6x + 21

⇒ (35 - 21 = 6x - 5x).

⇒ 14 = x 

⇒ The greater number is thus (2x = 2 × 14 = 28).

Hence, the greater number is 28.

Formula used

Successive discount = x + y - xy/100

Total discount on article = (Article get free)/(Total articles) × 100

Calculation

Scheme I. Two successive discounts of 12% each.

So, effective discount for scheme I is = 12 + 12 - (12 × 12)/100

= 24 - 1.44 = 22.56%

Scheme III. Buy 5 get 1 free

So, effective discount for scheme II is = (Article get free)/(Total articles) × 100

= 1/(5 + 1) × 100 = 16.67%

Scheme iv. Buy 6 get 2

So, effective discount for scheme III is = (Article get free)/(Total articles) × 100

= 2/(6 + 2) × 100 = 25%

So, the answer is Scheme (iii).

The answer is (option 2).

Formula used

sin 30 = 1/2

Calculation

sin2 30 + sin2 40 + sin2 45 + sin2 55 + sin2 35 + sin2 45 + sin2 50 + sin2 60

⇒ (1/2)² + sin² (90 - 50) + 2sin²45  + sin2 (90 - 35) + sin2 35 + sin2 50 + (√3/2)²

⇒ 1/4 + cos2 50 + 2(1/√2)² + cos2 35 + sin2 35 + 1 + sin2 50 + 3/4

⇒ 1/4 + 3/4 + 2(1/2) + cos2 50 + sin2 50 + cos2 35 + sin2 35 

⇒ 1 + 1 + 1 + 1 = 4

 Key Points

• The given sentence is in Simple Future Tense and in Passive Voice.
• The rule for changing a Simple Future Tense from Active voice to Passive voice or Passive to Active Voice:
• To convert a sentence from passive voice to active voice, we need to identify the subject (who is performing the action) and make it the subject of the sentence.
• Structure: 
• Object + will + be + V3 + by Subject (Passive Voice)
• Subject + will + V1 + object (Active Voice)
• Example: 
• A song will be sung by Esha.​ (Passive Voice)
• Esha will sing a song. (Active Voice)
• In active voice, the subject (other details) performs the action (giving) on the object (concerned teacher).
• In this case, the subject is "concerned teacher" and the object is "other details."
• The correct answer is Option 2.
  

Correct sentence: The concerned teacher will give the other details.
