Firstly, check the absentees in the qualification given in options

(i) B.A.

⇒ Number of absentees = (20/100)(40000000) – (22/100)(35000000) = 8000000 – 7700000 = 300000

(ii) Others

⇒ Number of absentees = (16/100)(40000000) – (14/100)(35000000) = 6400000 – 4900000 = 1500000

(iii) B.Com

⇒ Number of absentees = (21/100)(40000000) – (22/100)(35000000) = 8400000 – 7700000 = 700000

(iv) Now, lets check M.B.B.S because there is a – 3% change in it

MBBS

⇒ Number of absentees = (17/100)(40000000) – (14/100)(35000000) = 6800000 – 4900000 = 1900000

Since, MBBS has more number of absentees than all the 3 above

∴ the correct option is 4)

Distance covered by A in 3 seconds = 30 × 3 = 90 m

Relative velocity of B w.r.t. A = (50 – 30) m/s = 20 m/s

Now, taking A to be at rest, B has to cover 90 m to catch A

⇒ Time taken by B to catch A = 90/20 = 4.5 seconds

⇒ Total distance covered by B = 4.5 × 50 = 225 m = total distance covered by A

⇒ Total distance covered by both A and B = 225 × 2 = 450 m

∴ the correct option is 2)

Let the work done by A in 1 day be p

And,

Let work done by B in 1 day be q

⇒ Total work = 10(p + q)………….(i)

Now, when A works twice his efficiency

⇒ Work done by A in 1day = 2p

And, when B works 1/3^rd less than his efficiency

⇒ Work done by B in 1 day = q/3

⇒ Total work = work done by both in the new scenario

⇒ 10(p + q) = 6(2p + q/3)…………..(ii)

⇒ 10p + 10q = 12p + 2q

⇒ 8q = 2p

⇒ p = 4q

⇒ Total work = 10(p + q) = 10(5q) = 50q = 50p/4

⇒ Days taken by B to complete the work = 50q/q = 50

⇒ Days taken by A to complete the work = (50p/4)/p = 25/2

∴ the correct option is 1)

We know that,

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

Using the given equation, we can conclude that.

⇒ (x + y + z)² = 3(xy + yz + zx)

Putting x = y = z = n [where n is any natural number]

We get,

⇒ (7x + 3y – 5z)/5x = (7 + 3 – 5) /5 = 1

∴ the correct option is 2)

⇒ sin3θ = 1/sec2θ

⇒ cos(π/2 – 3θ) = cos2θ

⇒ π/2 – 3θ = 2θ

⇒ π/2 = 5θ

⇒ θ = π/10

To find: [3tan²(5θ/2) – 1]

⇒ 3tan²(π/4) – 1

⇒ 3 × 1 – 1 = 2

∴ the correct option is 3)

Divisibility rule of 4 states that if the last 2 digits of the whole number is divisible by 4, then the entire number is divisible by 4

⇒ M can be 0, 2, 4, 6, 8

⇒ M = 0 is the only option correct

∴ the correct option is 1)

Shortcut Trick

CI - SI for 2 years = P(R/100)²

⇒ 200 = P(20/100)² = P(1/5)² = P(1/25)

⇒ P = 200 × 25 = 5000 Rs.

Now,

Effective rate for SI in 1 year = 20%

Since, Interest is compounded half-yearly,

So, r = 20/2 = 10%, t = 2 cycle in 1 year

Thus,

Effective rate for CI in 2 year = 10 + 10 + (10*10)/100 = 21%

Hence, difference of interest = 21 - 20 = 1%

i.e. Difference = 1% of 5000 = 50 Rs.

∴ The correct answer is option (1).

Alternate Method

Calculation:

⇒ CI – SI = Rs. 200

Let the principal be P

So, we have

⇒ P(1 + R/100n)^nt – P - (P × R × T)/100 = 200

⇒ P(1 + 20/100)² – P - (P × 20 × 2)/100 = 200

⇒ 1.44P – P – 0.4P = 200

⇒ 0.04P = 200

⇒ P = 200/0.04 = Rs. 5000

Now, the difference when compounded half yearly

⇒ [5000(1 + 20/200)² – 5000] – (5000 × 20 × 1)/100

⇒ [5000(1.1)² – 5000] – 1000

⇒ [5000(1.21) – 5000] – 1000

⇒ 6050 – 6000 = Rs. 50

∴ The correct answer is option (1).

⇒ B.Tech's who have filled the form = (18/100) × (40000000) = 7200000

⇒ MBA’s who were present in the exam = (9/100) × (35000000) = 3150000

⇒ required difference = 7200000 – 3150000 = 4050000

∴ the correct option is 3)

Given:

Δ ABC ∼ Δ DEF

AB = 12 cm, DE = 8 cm

Concept used:

Two triangles are said to be similar to each other, if

(1) their corresponding sides are proportional.

(2) their corresponding angles are equal.

Calculation:

Here, Δ ABC and Δ DEF are similar triangles,

∴ ∠ A = ∠ D, ∠ B = ∠ E, ∠ C = ∠ F

and AB/DE = BC/EF = AC/DF

Then, Δ ABC ∼ Δ DEF

⇒ Perimeter of Δ ABC/Perimeter of Δ DEF = AB/DE

⇒ 12/8

⇒ 3/2

∴ The ratio of Perimeter of ΔABC : Perimeter of ΔDEF = 3:2

Given,

⇒ tanθ = cotθ

⇒ tanθ = 1/tanθ

⇒ tan²θ = 1

⇒ θ = 45°, -45°

Now, for θ = 45°

⇒ tan²⁶(45°) = (1)²⁶ = 1

⇒ cot¹⁰⁰(45°) = (1)¹⁰⁰ = 1

⇒ tan²⁶θ + cot¹⁰⁰θ = 1 + 1 = 2

Since the powers are even therefore we can ignore θ = -45°

∴ the correct option is 4)

Note - 

Please read the question carefully. Question is, 50% of others are from B.Arch.

B. Arch. students percentage = 14/2 = 50% of others = 7%

⇒ Number of B.Arch students who filled the form = (50/100)(16/100)(40000000) = 3200000

⇒ Number of B.Arch students who were present = (45/100)(14/100)(35000000) = 2205000

⇒ Number of B.Arch students who did not gave the exam = 3200000 – 2205000 = 995000

∴ the correct option is 1)

⇒ Let a = x – 3, b = 1/(x – 3)

Given,

⇒ a + b = 4

To find: a³ + b³

We know that (a + b)³ = a³ + b³ + 3ab(a + b)

⇒ 4³ = a³ + b³ + 3[(x – 3)/(x – 3)]4

⇒ 4³ = a³ + b³ + 3 × 4

⇒ 64 – 12 = a³ + b³

⇒ a³ + b³ = 52

So, (x – 3)³ + [1/(x – 3)]³ = 52

∴ the correct option is 3)

Trick:

If x + 1/x = k then the value of x³ + 1/x³ will always be equal to (k³ – 3k)

Here k = 4

(x - 3)³ + 1/(x - 3)³ = k³ – 3k = 4³ - 3 × 4 = 64 - 12 = 52

∴ Answer is 52

Let the side of triangle be ‘a’

Given,

⇒ π(R² + r²) = 770 cm²

Where, R = circumradius and r = in-radius

⇒ R² + r² = 245 cm²

For equilateral triangle,

⇒ R = a/√3

And,

⇒ r = R/2

⇒ a²/3 + a²/12 = 245

⇒ 5a²/12 = 245

⇒ a² = 588

⇒ a = 24.24

Now, area of an equilateral triangle with side a = √3a²/4

⇒ Required area = (588/4)√3 = 147√3

∴ the correct option is 2)

Let the price of one apple originally be ‘a’ paise

And,

Let the total number of apples be ‘b’

⇒ Total price of apples = ab

Rs 16 = 1600 paise

⇒ 1600 = ab (given) 

⇒ New price of one apple = a(1 + 33.33/100) = 1.3333a

After the increase in price,

⇒ Number of apples = b – 4

⇒ 1600 = 1.3333a × (b – 4)

⇒ 1600 = 1.3333a × [(1600/a) – 4]

⇒ 1600 = (4a/3) × [(1600 – 4a)/a]

⇒ 1200 = 1600 – 4a

⇒ 400 = 4a

⇒ a = 100

∴ the correct option is 1)

After an increase of 33.33% in the price of apples, a customer can purchase 4 apples less for Rs. 16. 

So, 33.33% of Rs. 16 is the price of 4 apples

Now price of 4 apples after increment = 16 of 33.33% 

⇒ Price of 4 apples after increment = 16 × (1/3) 

⇒ Price of one apple after increment = (16/3) × (1/4) = 4/3 

Price of one apple before increament = 4/3 × 3/4 = Rs. 1 = 100 paise 

∴ Price of one apple before increament is 100 paise.

Given,18% of total people who have filled the forms are doing MBBS

⇒ Total number of MBBS students who have filled the form = (17/100)(40000000)

⇒ Total number of MBBS students from XYZ university who have filled the form = (18/100)(17/100)(40000000)

⇒ required value = 1224000

∴ the correct option is 2)

Let the total number of employees before inflation be 5a

And,

Let the average salary per employee be 7b

Total salary given by company = 5a × 7b = 35ab

Total number of employees after inflation = 3a

Average salary per employee after inflation = 8a

Total salary given by company now = 3a × 8b = 24ab

35ab – 24ab = 55000 (given)

⇒ ab = 55000/11 = 5000

Initial expenditure of company = 35ab = 35 × 5000 = 175000

∴ the correct option is 3)

We know that the diagonal of a parallelogram bisects each other

⇒ Centroids of ∆ABC and ∆ADC lie on BD

Also, the centroid divides the median in a ratio of 2:1

Let the point of intersection of both the diagonals be O

⇒ PO = 1/3(BO)…………(i)

⇒ OQ = 1/3(OD)…………..(ii)

Adding (i) and (ii)

⇒ PO + OQ = 1/3(BO + OD)

⇒ PQ = 1/3(BD)

⇒ PQ = 12 cm

∴ the correct option is 3)

Given,

⇒ x(2x + 3) = 90

⇒ 2x² + 3x – 90 = 0

⇒ 2x² – 12x + 15x – 90 = 0

⇒ 2x(x – 6) + 15(x – 6) = 0

⇒ (2x + 15)(x – 6) = 0

⇒ x = -15/2 (neglect, as it is given that x is positive)

⇒ x = 6

Also,

⇒ 7y^-1/2 + 2y^-1/2 = y^1/2 

⇒ 9y^-1/2 = y^1/2 

⇒ y = 9

⇒ required value = x² + y² = 6² + 9² = 117

∴ the correct option is 3)

Given,

⇒ x/y = 4/9

⇒ x = 4y/9

Substituting y = 9x/4 in the required value

⇒ [(7x² – 19xy + 11y²)/y² = 7(4y/9)² – 19 × (4y/9)y + 11y²]/y²

⇒ [7 × 16y²/81 – 19 × 4y²/9 + 11y²]/y²

Taking y² in common from the numerator

⇒ 112/81 – 684/81 + 891/81

⇒ 319/81

∴ the correct option is 3)

Connect line CF.

Then area of triangle DFC = 1/2 × DF × EC = 1/2 × 40 × 60

= 1200  cm2 = 1/2 × DC × GF

We know that the area of a triangle is half the area of a rectangle, which has the same base and altitude as those of the rectangle.

Since ΔDFC has the same base(DC) and altitude(GF) as ABCD.

⇒ Area of rectangle ABCD = 2 × area of triangle DFC

⇒ Area of rectangle ABCD = 2 × 1200

= 2400 cm2

Let the marked price be m

Applying first discount, we get

⇒ Selling price = m × [1 – (15/100)]

⇒ Selling price = 0.85m

Applying second discount, we get

⇒ New sellingprice = 0.85m × [1 – (35/100)]

⇒ New selling price = 0.85m × 0.65

⇒ New selling price = 0.5525m

⇒ Net discount = m – new selling price = m – 0.5525m = 0.4475m

⇒ Net discount% = [0.4475m/m] × 100 = 44.75

∴ the correct option is 1

Shortcut TrickFormula Used: 

Effective discount when two discounts are offered,

⇒ a + b - (a × b)/100

Calculation:

⇒ 15 + 35 - (15 × 35)/100

⇒ 50 - 5.25

⇒ 44.75

Given,

⇒ a + b = 5

⇒ b + c = 7.5

⇒ c + a = 8.5

Adding all the 3 equations, we get

⇒ 2(a + b + c) = 5 + 7.5 + 8.5

⇒ a + b + c = 21/2 = 10.5

Now,

⇒ Average = (a + b + c)/3 = 10.5/3 = 3.5

Let the original length of side of a square be ‘a’

⇒ Area of original square = a²

⇒ Area of the new square = a²(1 + 69/100)

⇒ Area of the new square = 1.69a²

⇒ Length of side of new square = √(1.69a²)

⇒ Length of side of new square = 1.3a

Since, % increase in the length of side is k

⇒ k = [(1.3a – a)/a] × 100

⇒ k = 30%

∴ the correct option is 1)

Given,

Side of an equilateral triangle (a) = 12 cm

⇒ In-radius(r) = (1/2) × a × cot(π/3)

⇒ r = (1/2) × 12 × (1/√3) = 6/√3 = 2√3 cm

Now,

⇒ Circumradius(R) = a³/4rs

Where s = semi perimeter

⇒ Semi perimeter, s = 3a/2 = 36/2 = 18 cm

⇒ R = 12³/[4 × (6/√3) × 18]

⇒ R = 1728√3/432 = 4√3 cm

Required value = R – r = 4√3 – 2√3 = 2√3 cm

∴ the correct option is 3)

Given:

sin( – π/3) + cos( – π/6)

Formula used:

sin(-θ) = -sinθ, cos(-θ) = cosθ 

Calculation:

⇒ sin(–π/3) = - sin(π/3) = –√3/2

⇒ cos(–π/6) = cos(π/6) = √3/2

So, required value = (–√3/2) + √3/2 = 0

∴ The correct option is 1.

Correct Answer: of  

‘approve of’ means ‘give consent or assent to something’. Therefore, it fits the context of the sentence in not giving consent to the plan of travelling to Uttarakhand.

The correct answer is option 3.

Key Points

• Since the sentence is talking about '...popular today...' and the second part of the sentence also talks about people comparing with their past pattern of not having organic pulses, the word have doesn't agree with lived
• We have to compare two ways of life in the past and present
• The phrase "have ever lived" implies that the action of living without organic pulses is still continuing in the present time, which is not correct.
• The sentence refers to the past, so the correct phrase should be "how they ever lived without them." This phrase implies that people managed to live without organic pulses in the past, without implying that they still do not use them in the present.

Thus the correct sentence is: Organic pulses are so popular today that many people wonder how they ever lived without them.

Correct Answer: No improvement  

The sentence is correct as it follows all the rules of tenses and maintains the structure properly. The action of playing cricket was done when he saw Ankit, i.e., they were going on simultaneously.

Correct Answer: QRPS

The first sentence must be Sentence Q, which introduces the crude mineral oils. It is followed by its definition, which is Sentence R. Also, it is clear that Sentence P must be followed by Sentence S, as P uses the word ‘carbon’ first. Therefore, the correct sequence is QRPS.

Correct Answer: To outshine

• These two words are opposite because clandestine implies secrecy, concealment, and keeping things hidden, while open implies transparency, accessibility, and the absence of secrecy.
• Clandestine activities are intentionally kept hidden or private, whereas open activities are visible, accessible, and known to others.

Therefore, the correct answer is: Open.

Additional Information

Jiffy is an informal term for a short period of time. ‘In a jiffy’ means to ‘do something very quickly’.

An example sentence is: ‘He promised to do the tasks assigned to him in a jiffy’.

The correct answer is The teacher asked the student if he had brought his lunch.

Key Points

• The given sentence is in Direct Speech. As per the question we have to change it into Indirect Speech.
• The process of transformation as follows: 
• The given question is an example of an Interrogative sentence.
• 'Said to' will be changed into 'asked'.
• 'If' conjunction will be added to represent whether something is true or not
• An interrogative statement is converted into an assertive statement. Thus, the helping verb will be placed after the subject.
• 'You' will be changed into 'he'. (Second person->third person)
